Hydrolysis Of An Unknown Ester

Robert Paulson Organic Chemistry 1 4/25/2011 science lab describe: Hydrolysis of an unnoticeable Ester, Parts 1, 2, & 3 incomprehensible Ester: C passing Purpose: The purpose of these terzetto labs consisted of three interdependent goals by which identification of C release and is incident response, could be achieved. Firstly, A specific carboxyl venomous and its accompanying alcohol were synthesized via hydrolysis. Secondly, the carboxylic acid was precipitated and accordingly purified via vacuum filtration. Lastly, deterrent of the carboxylic acid and the alcohol were performed via melting point scour and nuclear magnetized resonance spectroscopy, respectively. Chemical Equation for mysterious C Red: Procedure and Observations: Week 1: A 100-mL round nooky flask was set-up for heating under reflux with a magnetized stir bar and the following ingredients in the flask: 3.44g NaOH, 4.60 mL distilled water, 9.60 mL ethylene glycol, and v irtually 5 mL of Unknown Ester C Red. The classification was brought to a boil and upon sight the reflux ring, the mixture was boiled in the flask for approximately thirty minutes. During the thirty min. period, precipitate was observed forming in the flask. by and by having cooled to slightly above board temperature, a simple distillate apparatus was assembled.

The mixture was then distilled until 2.20 mL had been collected. The boiling range of the liquid collected from the distillation process was recorded as 86-97°C [CORRECTED VALUE: 88.5-99.9°C]. Approximately, 13 mL of distilled water was added to the remain m ixture in the reaction flask. The reaction f! lask was secure and left for week devil of the lab. Week 2: Upon incoming the lab, a separatory move was set-up in a ring stand. The contents of Week 1s 100-mL flask were transferred into the separatory funnel via a normal funnel. A measured 10.50 mL summate of diethyl ether was added to the separatory funnel, causing the mixture to separate into two incompatible layers.
