Description
серы и 8,1 вес. % сульфидной серы. Отработанна серна кислота (246 мл) 72%-ной концентрации содержит 9% растворимых органических примесей и 15% воды.sulfur and 8.1 wt. % sulfide sulfur. Used sulfuric acid (246 ml) at a 72% concentration contains 9% soluble organic impurities and 15% water.
Предмет изобретени Subject invention
Способ получени концентрата, содержащего нефт ные сульфиды, из нефт ных дистилл тов экстракцией серной кислотой, о т л и ч а ющ и и с тем, что, с целью новышени выхода целевого продукта и упрощени технологии процесса, экстракцию ведут в токе инертного газа технической серной кислотой процесса алкилировани , содержащей 8-15% органических примесей, с последующей реэкстракдией полученного экстракта непол рным органическим растворителем с одновременным разбавлением его водой до 70-72%ной концентрации.The method of obtaining a concentrate containing petroleum sulphides from petroleum distillates by extraction with sulfuric acid is also so that, in order to increase the yield of the target product and simplify the process technology, the extraction is carried out in a stream of inert gas of technical sulfuric acid alkylation process containing 8-15% of organic impurities, followed by reextraction of the obtained extract with a non-polar organic solvent with simultaneous dilution with water to 70-72% concentration.
