Abstract
Compositions comprise lower molecular weight aliphatic hydrocarbons stabilized with acetylenic halides. The chlorinated hydrocarbons may be previously purified. The boiling point of the acetylenic halide used is preferably within 20 DEG C. of the boiling-point of the chlorinated hydrocarbon. The composition may also include a light stabilizer such as isoeugenol. Tests on tetrachloroethylene stabilized with 3-chloro-1-propyne, 3-iodo-1-propyne, 4-bromo-1-butyne, 1 : 4-dichloro-1-butyne, 1-chloro - 1 - hexyne, 4 - phenyl - 1 - chloro - 1 -butyne, and 4 - chloro - 3 - methyl - 1 - butyne with or without isoeugenol as light stabilizer, are described. Other chlorinated hydrocarbons also stabilized by the above products include di-and tri-chloroethylene, trichloroethane, pentachloroethane, chloroform and carbon tetrachloride. Other specified acetylenic halides include 4-chloro-1-butyne, 4-chloro-2-butyne, 4-chloro-4-methyl-1-butyne, and chloro pentynes, heptynes, octynes, nonynes and decynes, isomers of such and cyclic substituted derivatives, such as cyclohexyl. Starting compound. 3-Chloro-1-propyne is prepared by reacting propargyl alcohol and phosphorus trichloride.
