Discussion: Extraction and crystallization- The purpose of this lab was to extract and crystallize compounds in a mixture using acids and bases. 1 gram of the unknown was dissolved into 30 mL of ethyl acetate. The mixture was then transferred to a separatory funnel. Using aqueous solutions of different pH we were able to separate organic acids‚ bases and neutral compounds from each other. Using three 10 mL portions of HCl‚ we reacted the HCl with the base in solution. This made it possible to

Experiment 3: Isolation of Chlorophyll from Spinach and Chromatography Performed February 14th and 16th By Kyle Herzog Organic Chemistry 344 Section 807 Spring 2012 Objective: The purpose of the experiment is to extract pigments from spinach leaves and separate them by column and thin layer chromatography‚ determining Rf values for the pigments. Equations: Rf= Distance travelled by a given compound/Distance travelled by a solvent solution 1. Crude- 4.25/5.5= 0.773 2. Carotene-

as the main ingredient for deodorizer. The procedure involved taking the fruit itself out followed by cutting the thick white part inside the shell. Subsequently‚ the thick white part is placed in a container together with 750mL of water‚ 100mL of ethyl alcohol and 5 tablespoons of potassium sorbate. The usage of potassium sorbate is significant because it serves as a preservative for the durian fruit. After 18-24 hours‚ the liquid was then distilled so that the extract can be acquired. When the distillation
