Recovery of 4-Amino Phenol from aqueous solution using different techniques

Chemical Engineering

4-Aminophenol belong to a class of organic substances of particular environmental interest. Due to their widespread discharge into environment and their toxicity to many living organisms, phenol and its amine derivates are presently found on most priority lists of hazardous substances. Different techniques to separate phenolic compounds from aqueous solution has been developed which includes extraction, absorption, distillation , freeze crystallization ,etc. To separate a phenolic compound from effluent & to recover it is an essential need for the industry today. This report presents experimental for aqueous solution of 4- aminophenol with help of Distillation and freeze crystallization system which is utilized in finding % recovery of 4- aminophenol. Using freeze crystallization method we did not get any recovery of 4-aminophenol so freeze crystallization method don’t work in recovery of 4-aminophenol from aqueous solution. then used distillation technique we get 80% recovery of p-aminophenol from aqueous solution. Based on experimental data, we proposed to design the batch distillation column.
