Abstract

PURPOSE: To prevent effectively the deposition of petroleum sludge, by adding a sulfated sorbitan fatty acid ester salt to petroleum.
CONSTITUTION: To petroleum, 5W500ppm of a sulfated sorbitan fatty acid ester salt, e.g., those derived from esters obtained by heating and dehydrating a mixture of sorbitan or sorbitol and a 12W22C straight-chain or branched saturated or unsaturated natural or synthetic fatty acid or a combination of these, is added. When the amount of the additive to add is 5ppm or less, its effect is small, but when it exceeds 500ppm, its effect is not so great and also not economical. The preferred SO3 content of the sulfated sorbitan farry acid ester salt is 5W30wt%.
