Abstract

PURPOSE: To prepare the stable and low toxic titled compound which can be used even to the washing of Al, Fe, etc., by adding a reaction product of 1,2,3-benzotriazole, etc. and diphosphonic acid to 1,1,1-trichloroethane.
CONSTITUTION: 1,1,1-Trichloroethane is stabilized by adding 10W5,000ppm of the reaction product of (A) 1,2,3-benzotriazole or tolyltriazole and (B) a diphosphonic acid of formula (R is 1W8C alkyl; X is H, OH, or NH2), pref. 1-hydroxyethylidene- 1,1-diphosphonic acid or 1-hydroxymethylidene-1,1-diphosphonic acid. The compounding ratio of the triazoles to the diphosphonic acid is (1W4) to 1 (molar ratio), and the reaction product can be synthesized by heating and stirring the mixture at ≥30°C, pref. 60W80°C for ≥1hr.
