Dehydration and Gc Lab Report

An alcohol an be converted to an alkaline by dehydration, which is often brought on by heating the alcohol with either 85% phosphoric acid or concentrated sulfuric acid The objective of this experiment is to dehydrate 3-methyl-3-pentagon to obtain the product mixture of isomeric alleles 3-methyl-pentane and 2-ethyl-l- butane. Then use the gas chromatography to…

Fractional Distillation Organic Lab Report

If such ideal conditions are not possible as is usually the case”then simple distillation can be applied as long as he liquid in question is composed of compounds that differ in volatility such that their boiling points differ by at least 40 to 50 degrees Celsius.
