Stabilized 1,1,1-trichloroethane

Abstract

1,1,1-trichloroethane containing as the essential metal stabilizers (1) from 3.5 to 6 volume percent of (a) a mixture of 3-methyl-1-butyn-3-ol ##EQU1## and tertiary amyl alcohol ##EQU2## wherein said 3-methyl-1-butyn-3-ol is present in at least 1.75 volume percent of said mixture or (b) 3.5 volume percent 3-methyl-1-butyn-3-ol; (2) 0.5 to 2 volume percent of a nitroalkane selected from nitromethane or a mixture of nitromethane and nitroethane, said nitromethane or mixture of nitroalkanes being present in at least 1.0 volume percent when said mixture (1a) is 3.5 volume percent and 0.75 volume percent when said (1b) is 3.5 volume percent; and, (3) 0.5 to 1 volume percent of an alkylene oxide having 4 to 6 carbon atoms including cyclohexene oxide as the essential acid acceptor. A preferred composition consists of 2 volume percent each of 3-methyl-1-butyn-3-ol and tertiary amyl alcohol, 1.0 volume percent nitromethane and 0.75 volume percent 1,2-butylene oxide.
