Glycidyltrimethylammonium chloride is a chemical compound from the group of substituted quaternary ammonium salts .
Extraction and presentation
Glycidyltrimethylammonium chloride can be synthesized from epichlorohydrin , trimethylamine, and water. Hydrochloric acid and sodium hydroxide are required as catalysts . Commercial products contain 3-chlorohydroxypropyltrimethylammonium chloride (<4%), 2,3-dihydroxypropyltrimethylammonium chloride (<3.5%) and some other compounds (e.g. traces of epichlorohydrin) as impurities.
properties
Glycidyltrimethylammonium chloride is a flammable, odorless, whitish, hygroscopic solid. It decomposes after melting.
use
Glycidyltrimethylammonium chloride is mainly used for the cationization of starches in the paper industry. In 2001 about 6000 tons of the compound were used for this. It is usually sold as a 75% solution in water.
safety instructions
There are some known cases of dermatitis and sensitization caused by the commercial handling of glycidyltrimethylammonium chloride despite working under safety precautions. The compound is directly mutagenic and carcinogenic.
