Technical Document

Brief Overview

Monochloroacetic acid (MCA) is a colorless crystalline material, which is highly soluble in water and soluble in organic solvents. Its vapor pressure at room temperature is moderate with reported values between 0.2 hectopascals (hPa) (crystalline substance) and 10 hPa (solution in water). MCA has a pungent odor. It is one of the most important halogenated derivatives of acetic acid. MCA is a reactive compound that can undergo various reactions to form a number of intermediates.

 

Manufacturing Process

The process for preparing monochloroacetic acid (MCA) comprising a chlorination step and a hydrogenation step. Its process comprises the removal of aldehydes from a process stream by oxidation using a peroxycarboxylic acid. A preferred peroxycarboxylic acid comprises peracetic acid. Preferably, the process is carried out at a temperature of 60–100° C., most preferably at atmospheric pressure. Preferably, an about equimolar amount of peroxycarboxylic acid is used relative to the molar amount of aldehydes present in the process stream. A practical choice for the process stream is the acetic acid recycle stream. The invention process provides a clear and colourless MCA end product.

Intermediate of carboxymethylcellulose and -starch can be used as thickening agent for detergents, oil drilling, paper, food and pharma applications, Production of agrochemicals like herbicides (e.g. 2,4-D and MCPA) or insecticides e.g. (dimethoates), Raw material for betaine production (personal care), Manufacturing of thioglycolic acid for UV-light stabilizers in PVC and thioglycolic acid ester as additives in cosmetics, Further applications: vitamins, synthetic caffeine, malonates, glycine.
