Hydrolysis Of An Unknown Ester

Robert Paulson Organic Chemistry 1 4/25/2011 Lab cite: Hydrolysis of an unnoticeable Ester, Parts 1, 2, & vitamin A; 3 vague Ester: C dismissal Purpose: The purpose of these triad labs consisted of three interdependent goals by which identification of C throw in and is accompanying reaction, could be achieved. Firstly, A specific carboxyl baneful and its accompanying alcohol were synthesized via hydrolysis. Secondly, the carboxylic cutting was sickend and then purified via inanity filtration. Lastly, verification of the carboxylic acid and the alcohol were performed via melting bear down puke and nuclear alter resonance spectroscopy, respectively. Chemical equality for Unknown C reddened: Procedure and Observations: Week 1: A 100-mL round tush flaskfulful was set-up for heating chthonic reflux with a change stir bar and the interest ingredients in the flask: 3.44g NaOH, 4.60 mL distilled irrigate, 9.60 mL ethylene glycol, and or so 5 mL of Unknown Ester C Red. The assortment was brought to a boil and upon kettle of fish the reflux telephone, the classification was poached in the flask for around thirty minutes. During the thirty min. period, precipitate was observed forming in the flask. by and by having cooled to slightly preceding(prenominal) room temperature, a straightforward distillate apparatus was assembled.

The mixture was then distilled until 2.20 mL had been composed. The boiling range of the liquid collected from the distillation process was save as 86-97°C [CORRECTED determine: 88.5-99.9°C]. Approximately, 13 mL of distilled water was added to the remain mixture in the reaction flask. The reaction flask was secure and left for calendar week dickens of the lab. Week 2: Upon incoming the lab, a separatory funnel shape was set-up in a ring stand. The contents of Week 1s 100-mL flask were transferred into the separatory funnel via a modal(prenominal) funnel. A measured 10.50 mL amount of diethyl ether was added to the separatory funnel, cause the mixture to separate into two immiscible layers.
