Abstract
PURPOSE:To obtain a large amount of the titled colorless oil, useful as an oil for refrigerator and an electrically insulating oil, having excellent low- temperature fluidity, solubility and stability in high yield, by treating an extract prepared as a by-product in purifying process of lubricating oil with an alkali solution. CONSTITUTION:A lubricating oil component collected from crude oil or a deasphalted oil obtained by treating the distillation residue of crude oil is extracted with a solvent such as furfural, phenol or N-methylpyrrolidone having selective affinity for aromatic hydrocarbons. The prepared extract is treated with an aqueous solution of an alkali or an organic alkali solution (e.g. solution of an alkali in alcohol, acetone or glycerin) to give the aimed oil. The oil is useful as a solvent for slightly soluble additives such as an extending agent for white rubber, an improver for cetane number and an anti-foaming agent besides the uses mentioned in the purpose.
