Esterfication Lab Procedure

Submitted by benjaminburk on Tue, 04/10/2018 - 10:37

.97 mL of propionic acid and 1.19 mL of 3- methyl- 1- butanol were added to a 5 mL round bottom flask. 4 drops of sulfuric acid were then added to the flask and the contents were thoroughly mixed. Boiling chips were added to the flask and the flask was attached to the distillation head and placed a 45 degree angle on the sand bath. The flask was brought to a slight flask for 15 minutes. After 15 minutes the contents of the side arm were gently poured back into the flask, being sure that no water was returned. This process was repeated two more times, after which the mixture was allowed to cool. 1 mL of water was added to the mixture and mixed thoroughly, the aqueous layer was removed and placed in the waste beaker. 1 mL of sodium bicarbonate was then added and mixed in thoroughly before removing the aqueous layer again. This process was repeated once more. Then 1 mL of saturated aqueous sodium chloride was added, mixed and the aqueous layer was removed one final time. A dozen anhydrous CaCl2 spheres were added to the mixture and the mixture was allowed to “dry” for 10 minutes. The remaining liquid after the 10 minutes was removed via pipet and put into a dry tarred vial. The weight, smell, percent yield and IR graph were all obtained and recorded for the remaining liquid.

Cellulose PP

Photosynthesis is an essential reaction in order to sustain life. The products of the essential reaction include oxygen and glucose. Besides the obvious benefits in the production of glucose and oxygen these products prove to have many important functions within the cell. The glucose produced from the reaction is converted into storable starch. This starch can then enter the plasma membrane where it interacts with the cellulose synthesis complex. The product of this interaction is cellulose, the most prominent and strongest component of the cell wall. Considering that cellulose is the most prominent component of the cell wall and is present in the majority of plants in the world many scientists consider it one of the most abundant organic compound on earth. Cellulose is also a large source of fiber in the average humans diet.

Cyclohexane synthesis procedure

Submitted by benjaminburk on Sun, 04/08/2018 - 18:49

2 grams of cyclohexanol was added to a 250ml round-bottomed flask. .5ml of phosphoric was then added to the flask as well. A distillation of the mixture was then performed with the first drop occurring at 60 degrees Celsius and the plateau occurring at approximately 68 degrees Celsius. Lower layer of the remaining liquid was removed for waste. A washing procedure was followed with 1 ml of water, then 1 ml of NaOH and finally 1 ml of brine. After each washing sequence the lower layer of the liquid was removed and added to the waste beaker. The remaining liquid was then transferred to a new vial and CaCl2 was then added and contents were left to dry for approximately 7 minutes. The liquid in the beaker was then removed and placed in a new tarred test tube. The remaining liquid was then weighed and a final weight and percent recovery was recorded. Finally a potassium permanganate, bromine dichloromethane, IR and gas chromatography test were performed on the liquid to test for purity and contents.

Trimyrisistin Discussion section

Submitted by benjaminburk on Sun, 04/08/2018 - 15:02

 Trymyristin was isolated from nutmeg and the remaining product was hydrolyzed in an attempt to synthesize Myristic acid. The preparation process described in the procedure, the filtration process and recrystallization process were all followed successfully. The Trymyristin was synthesized with a 30.9% percent yield after one round of recrystallization and with a 38.5% percent yield after the second round. The Myristic acid was synthesized with a 40.32% percent yield. The compound synthesized at all stage of the experiment can be concluded to be the desired product and very pure because of the small range in the melting point observed. Although the Trymyristin that was recrystallized once has a wider range of melting I believe it is still pure and the wide range is due to human error within the procedure of melting the product.

Procedure for Trymyristin Isolation

1 gram of nutmeg was added to a round bottom Erlenmeyer flask and then 3 mL of TBME was added to the flask as well. The distillation process was then followed proceeded by a micro scale filtration that occurred pipet-full by pipet-full. 2 mL of TBME was then added again to the nutmeg and the filtration method was repeated. A light air stream was then run over the crude product and after a 5 minute drying period the weight was obtained. 12 mL of acetone was then added to the flask the solid was dissolved via a recrystallization process. The dissolved solution was cooled at room temperature and in an ice bath, the vacuum filtration method was then followed and the crystals were allowed to dry. A final weight and MP was then obtained. Following the filtration .072g of Trymyristin was then transferred to a round bottom flask. 2 mL of 6 M NaOH, 2 mL of 95% Ethanol and boiling chips were added to the flask. The solution was then refluxed for approximately 45 minutes. The remaining Trymyristin was then recrystallized and filtered a second time. The MP and final weight of the Trymyristin was recorded. After 45 minutes the refluxed solution was cooled at room temperature and transferred to a 50 mL beaker containing 8 mL of water. 2 mL of concentrated HCl was then added to the solution. The beaker was then cooled on ice while being stirred. The solid was collected via vacuum filtration and was allowed to dry overnight before obtaining a final weight and MP.

Laughter For Medicine

Submitted by benjaminburk on Wed, 04/04/2018 - 10:35

In honor of a belated April fools day the Journal of Ethics published a short research article describing the extensive benefits of laughter. Laughter is good for the soul is a common saying throughout culture, but this article identifies the numerous benefits that laughter has on the physical health of patients. Laughter is a common therapy utilized at mnumerous hospitals and clinics around the country. The University of New Mexico Hospital actually has a "humor room" for patients. Physiologists have concluded through various studies that laughter helps with ventilation and clearing mucous. These benefits show that laughter can be an effective treatment for patients that suffer from chronic obstructive lung diseae. Laughter also increase perfusion by increasing overall circulation within the circulatory system. 

Persuasive dog write up Revised

Submitted by benjaminburk on Mon, 04/02/2018 - 20:38

The breed of dog that should be saved is the Belgian Malinois. The Belgian Malinois is a highly intelligent breed that can be trained to perform an assortment of tasks efficiently making it an ideal companion. It also has an extremely low number of chronic health problems like many other breeds face, making it a very easy dog to care for as well. Being a dog owner myself I have learned what it takes to care for a dog, meaning I understand the importance of an obedient and healthy dog and by saving this breed we are giving the human race the ability to experience exactly what it's like to have a lifelong companion that is willing to do anything to protect them.

Now you may assume that the dog I own is in fact a Belgian Malinois, but that is incorrect. The dog a I own is a cavapoo and after extensive research the choice, although not easy,  was clear, there was no better breed to save than the Belgian Malinois. If you want to provide the human race with an intelligent, reliable, healthy and loyal companion than side with me and save the Belgian Malinois.

PCOS PP

Submitted by benjaminburk on Sun, 04/01/2018 - 23:10

Polycystic ovary syndrome (PCOS) is a common metabolic and endocrine disorder in premenoausal women. Recent studies have produced evidence that PCOS is a disorder with strong environmental and epigenetic influences, including diet and other lifestyle factors. PCOS frequently appears in assocaition with metabolic disorders, cardiovascular risks, insulin resistance and obesity. This disorder does not require complicated treatments or extensive changes to ones life styles, but have found that the disorder requires appropiate therapies that address hyperandrogenism, a consequence of metabolic disorders. 

REvised Research Desugn Draft

The experiment we want to run is comparison of physical attributes between the campus pond and the nearby puffers pond. The physical attributes that would be tested would be temperature, pH, turbidity, plankton diversity, emergent vegetation, submerged vegetation, water velocity and direction and general biodiversity of surroundings. Each group will be given a physical attribute and will be expected to test both bodies of water for the specific attribute. The temperature will be tested by approaching the shore and inserting a the thermometer into the water for 1 minute and recording the resulting temperature after the minute. pH will be tested by inserting a pH strip into the water and approximating the pH based on the color that appeared. Turbidity will be tested using a homemade secchi disk, which will be constructed by attaching a rock covered in tin foil to a piece of string of approximately 3 feet. This homemade disc will then be lowered into the water and the length of rope submerged will recorded. Plankton biodiversity will tested using a plankton net and then by taking a 1 mL sample and counting the amount of organisms present in the sample. Emergent and submerged vegetation will be recorded as present and not present. Water velocity and direction will found by a bottle of water filled up halfway and recording the time it takes to travel a set distance. General biodiversity will be recorded through descriptions of the vegetation and wildlife seen around the bodies of water. Once the groups have recorded the results the groups will not the similarities and differences of the findings between the two bodies of water. The groups are then expected to brainstorm reasons as to why the similarities and differences are present.
