Abstract
The invention comprises a method of stabilizing a halogenated hydrocarbon of up to 3 carbon atoms by adding thereto a composition containing propargyl alcohol, a phenol, a low-boiling secondary or tertiary amine and another s- or t-amine having a carbon chain of at least 4 carbon atoms linked to its amino nitrogen. A table is given of the stabilizing effects of such compositions containing propargyl alcohol, di-isopropylamine, and di-sec.-butylamine, with phenol, p-cresol, guaiacol, and methyl salicylate, on trichlorethylene in various tests. Other chlorinated hydrocarbons which may be stabilized similarly, include carbon tetrachloride, chloroform, ethylene dichloride and perchloroethylene. Other amines specified include low-boiling tertiary amines, and secondary or tertiary amines of 4-8 carbon chains. Other phenols specified include thymol, catechol, and generally aromatic compounds having a ring-attached OH group.
