Vegetable Oil-Based Peg Esters

Introduction

 

PEG esters are used as non-toxic, non-irritating, non-ionic emulsifiers and in formulating emulsifier blends, thickener, resin plasticizer, emollient, spreading agent, wetting and dispersing agent and viscosity control agents.

 

They also have application in the metal working, pulp, paper, textile and as defoamer for latex paintings.

 

Major Raw Materials: Vegetable oil fatty acids, poly ethylene glycols & acid catalyst

 

Brief Process Description

 

The process for the preparation of PEG ester involves esterification of PEG with palm & sunflower oil fatty acid mixture using a catalyst under N 2 atmosphere. Bleaching of the crude product results in PEG ester with the following specifications: AV, 3-4; Viscosity, 55-58 cst at 40ºC and 11-12 cst at 100 ºC. However the specification can be tailor made as per the requirement of the end use.

 

Scale of Demonstration: 1Kg/batch

 

Status of Commercialization

 

Process Know-how was transferred to one industry at 1Kg/batch scale.

 

Major Plant Equipment and Machinery Required

 

Jacketed reactor (2 lts), N 2 flushing system, efficient filtration & vacuum system.
