    摘要: A process for the production of an essentially ash-free oil stock from a lubricating oil containing ash-forming components comprising(a) contacting said lubricating oil with an aqueous ammonium salt treating agent;(b) removing a major portion of the water from the mixture resulting from combining said aqueous solution and said lubricating oil;(c) heating at least a portion of the product resulting from step (b) at a temperature in the range of about 320.degree. to about 420.degree. C. for a period of time sufficient to decompose at least a portion of any ammonium salts of sulfonic acid and dialkyldithiophosphoric acid that are contained therein;(d) cooling the product from step (c) to a temperature in the range of about 150.degree. to about 180.degree. C.; and(e) separating the solids from the product of step (d), optionally with subsequent hydrotreating and stripping of the oil thus obtained.

    摘要: A process for the separation and recovery of unsaturated aliphatic hydrocarbons from admixture with saturated aliphatic hydrocarbons which comprises contacting such a mixture with a complexing agent comprising cuprous salts of sulfonic acids and dialkyl phosphates under such conditions that the unsaturated hydrocarbons are preferentially complexed with the cuprous salts. In one embodiment, olefins are separated from paraffins by using a cuprous sulfonate dissolved in an aromatic solvent to form a complex with the olefin. The olefin can be separated from the resulting complex and the cuprous salt recycled for reuse.
