Use of the Acetophenone Fraction in a Chemical Method for Demercaptanization of Hydrocarbon Feedstock and Regeneration of Sulfide-Alkali Liquors

摘要

The possibility of using the unutilizable acetophenone-containing industrial waste in the alkylthiomethylation reaction of ketones for demercaptanization of hydrocarbon feedstock and regeneration of sulfide-alkaline liquors was shown. The reaction proceeds for 0.5-5 h at 20-50 deg C and a ketone: formaldehyde: sodium hydroxide: ethanol molar ratio of 2:2:0-2:0-2 per mole of sulfur. The conversion of active sulfur-containing compounds was as high as 97-100% with simultaneous production of practically useful #gamma#-oxoalkylsulfides.
