Production of white oil from West Siberian crudes
White oils, such as pharmaceutical white mineral oil, perfume oil, solvent for initiator of ethylene polymerization reaction, oil for the lubrication of high-pressure compressors in polyethylene production, and cable oils, are finding more and more industrial applications. The distinguishing feature of all of these oils is their high degree of dearomatization. The content of naphthenes plus paraffins, as determined by adsorptive separation on silica gel, is at least 98%. White oils are produced by multistage sulfonation of the original raw material (oil) with oleum or gaseous sulfur trioxide with subsequent neutralization and clay contact finishing. The advantages of gaseous sulfur trioxide over oleum are the lower consumption of sulfonating agent and the smaller amount of acid tar that is formed, giving higher yields of sulfonic acid that are in turn a raw material for the production of sulfonate additives. This paper presents results of a research program in which crude from West Siberia was tested as raw materials for the production of white oils. Results are presented which demonstrate suitability of crude tested for the production of perfume oil, pharmaceutical white mineral oil, S-220 cable oil, oil for use in polyethylene production (solvent for initiator of ethylene polymerization reaction), and compressor oil. 9 refs.
