The Consulting Chemists Institute has been asked to analyze the drug preparation of Aspirin to find out what percentages of aspirin‚ sucrose‚ and drug preparation. The purpose of this experiment was to determine the unknown component of panacetin. Panacetin contains aspirin‚ sucrose‚ and an unknown component. Dichloromate reacts with Panacetin to produce the sucrose as an insoluble solid. Aspirin is removed from the solution by reacting with sodium bicarbonate. The aqueous layer reacts with hydrochloric

Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast in 2 steps: first sucrose (a disaccharide whose

Also pure acetanilide is achieved. here are five major steps in the recrystallization process: dissolving the solute in the solvent‚ performing a gravity filtration‚ if necessary‚ obtaining crystals of the solute‚ collecting the solute crystals by vacuum filtration‚ and‚ finally‚ drying the resulting crystals giving us the pure sample of the compound

acetanilide behind. Experimental: For the separation of sucrose‚ we weighed out 3.048g of Panacetin onto a filter‚ and 50 mL of dichloromethane in a graduated cylinder. Then we transferred both the panacetin and dichloromethane into an Erlenmeyer flask and stirred it until the panacetin was dissolved. We let it dry by gravity and set it aside to dry. The filter paper weighed about 1.320g and sucrose weighed out at 1.028g. Sucrose also ended up on the outside rim of the filter paper. We then

pharmaceutical preparation of Panacetin‚ by using it ’s solubility along with other organic molecules. We know that Panacetin is made up of sucrose‚ aspirin and some other unknown substance. We know the substance has to be Phenacetin or Acetanilide. To help solidify our reasoning‚ we need a % recovery of 8-12% sucrose‚ 35-45% aspirin and 45-55% unknown. Sucrose for example is insoluble in dichloromethane‚ while aspirin is soluble in CH2Cl2‚ but not in H2O. The organic compound sodium hydroxide will

by making use of their solubilities and acid-base properties. Panacetin contains aspirin‚ sucrose and an unknown component that may be either acetanilide or phenacetin. Of the three components‚ only sucrose is insoluble in the organic solvent dichloromethane (CH2Cl2 or methylene chloride). The insoluble sucrose can be filtered out if Panacetin is dissolved completely in dichloromethane by gravity filtration or centrifugation leaving the soluble aspirin‚ acetanilide and phenacetin in the solution

Fermentation of Carbohydrates: Ethanol from Sucrose Objective: To demonstrate a fermentation process‚ isolate the ethanol produced by fractional distillation‚ determine the composition of the ethanol solution recovered‚ and make stoichiometric and yield calculations. Procedures: Fermentation Weigh out 20.0 g of sucrose and place it into a 250-mL Erlenmeyer flask. Add 100 mL of water and gently shake until all the sucrose has dissolved. To this solution add 0.60 g of dipotassium hydrogen phosphate

“Panacetin” Extraction and Evaporation & Identifying a Constituent of “Panacetin” Recrystallization& Melting-Point Measurement Organic Chemistry Lab Introduction: Panacetin purportedly includes sucrose‚ aspirin‚ and acetaminophen. However‚ the accuracy of Panacetin’s contents has been called into question by the Association for Safe Pharmaceuticals. Therefore‚ the lab must discover the accuracy of the ingredients listed on Panacetin’s label.
