Sodium trichloroacetate is a chemical compound of chlorine from the group of organic substituted carboxylic acid salts .
Extraction and presentation
Sodium trichloroacetate can be obtained by neutralizing trichloroacetic acid with a sodium hydroxide solution or sodium carbonate .
properties
Sodium trichloroacetate is a flammable, difficult to ignite, hygroscopic, yellowish solid that is easily soluble in water. It decomposes when heated above approx. 195 ° C, which can produce hydrogen chloride and sodium oxide . However, dichlorocarbene can also be formed.
use
Sodium trichloroacetate can be used as a polymerization catalyst for vinyl compounds and as a dyeing aid. It was also used as a herbicide in the past .
