Hydrocarbon oils containing 1 to 10 percent emulsified water and emulsifiers therefor

摘要

Hydrocarbon oils containing 1 to 10% emulsified water are provided, having as the emulsifier: (a) a nonionic surface-active ethylene oxide adduct having the general formula: <IMAGE> in which: n1=1 to 5; n2=a number selected to give a polyethylene glycol chain in a weight percent within the range from about 50 to about 60% by weight of the adduct; R=alkyl of from about one to about twenty-four carbon atoms, the alkylphenyl group having from about twelve to about thirty carbon atoms; and (b) the calcium salt of dodecylbenzene sulphonic acid. The weight ratio nonionic surface-active ethylene oxide adduct to calcium salt of dodecylbenzene sulphonic acid is from about 80:20 to about 40:60. The emulsifier emulsifies from 1 to 10% by weight of water in the hydrocarbon oil.
