The synthesis of acetaminophen: Experiment and Theory by Lorena Tribe on Prezi

synthesis of acetaminophen lab report

The outer solution was stirred at 37 ' C and a 3 mL of sample was removed at selected intervals. The literature melting point of acetaminophen is 169. It must be typed or written with blue or black ink. What could happen if room temperature solvent was used? The dried crystals were weighed and observed, and a small amount was set aside in order to determine the melting point. If 20 mL of water were added for every 1g of crude product then crystallization would occur in less quantity or not occur at all. Final Conclusion and error analysis To do Lab Report for Single and Double Replacement reactions : This is a formal lab report.

It is possible that we lapsed in our efforts to maintain this temperature, allowing other, unknown reactions to take place, contaminating our sample. When dissolution occurs following the addition of acetic acid a clearer mixture can be observed. When cooling, the solution should remain undisturbed. Words: 287 - Pages: 2. Citrus tissue culture: stimulation of fruit explants cultures with orange juice. Conclusions The purpose of the experiment was to identify the melting temperature of pure acetaminophen after undergoing synthesis. Acetaminophen is created when the amine group of p-aminophenol is acetylated by acetic anhydride.

Non-metals can be either solids or gases; they are neither ductile nor malleable. During the recrystallization the impure sample could have been extracted resulting in a low yield. The degree of substitution is lower than 2%. Make sure that you include the following: 1. The solution was again poured into a Büchner funnel and the crystals were dried for 5 minutes. The crystallization process is slow however crystal solids can be seen during precipitation. And the students will be divided into 4 groups with those 4 different predators.

The procedure stated in Chem 2120 experiment 6 Williamson Ether Synthesis of Phenacetin laboratory manual was followed without any major changes. The Merck Index said that the melting point varies from 169°C -170°C. Next we plugged in our numbers and found the molarity of the acid. The only difficulty encountered was that the percent yield was low due to careless errors in the laboratory. Nonmetals Poor in conducting heat and electricity generally as insulators, only at room temperature.

The purification of resulting polymer was conducted according to the method described above. If the solid is dissolved below the boiling point of the solution, too much solvent will be needed, resulting in a poor yield. It presents evidence on how some of the most financially complex companies and financial advisors estimated capital costs and focuses on the gaps found between theory and application. Step 8 Filter paper was placed into the center of the Buchner funnel so that all of the holes were covered. The standard acetaminophen sample spot had a retention factor value of 0.

This may have resulted in an incomplete reaction forcing the yield to significantly decrease. In order to obtain optimal results, a minimum of near-boiling solvent should be used for the recrystallization, and a minimum of ice cold solvent should be used for the rinse. Poly vinylalcohol -co-poly vinylchloroacetate — drug hydrolysis in presence of crown ether. Polyethylene glycol with chloroacetate endgroup—drug hydrolysis. Metal are ductile, and malleable.
