Abstract

Development of acidity in chlorinated hydrocarbons is retarded by incorporating a little free fatty acid and soap. For example, a mixture of about 2 per cent of oleic acid and up to 1 per cent of alkali soap is dissolved in carbon tetrachloride or trichlorethylene used to degrease metals. The mixture of acid and soap may be obtained by partially neutralizing a fatty acid, e.g. with caustic soda. Specification 155,595, [Class 91, Oils &c.], is referred to.ALSO:Development of acidity in chlorinated hydrocarbons is retarded by incorporating a little free fatty acid and soap.
