Abstract
1,1,1-trichloroethane is stabilised against metal-induced decomposition by incorporating a polyalkylene glycol monoalkyl ether.
Claims13
A stabilised solvent composition consisting essentially of 1,1,1-trichloroethane with a stabilising amount of from 0.01% to 5% by weight of a stabiliser which is a polyalkylene glycol monoalkyl ether of formula ##STR2## where R is an alkyl group containing 1 to 4 carbon atoms, R' is hydrogen or a methyl group and n is 2 or 3.
