Изобретение относится к химической и газовой промышленности, а именно - к одорантам, применяемым для одоризации сжиженных природных, нефтезаводских и органических соединений, не обладающих запахом. Сущность изобретения заключается в том, что одорант для сжиженных углеводородных газов содержит алкилмеркаптаны и дополнительно смесь низкомолекулярных диалкилдисульфидов C2-C8 (СНДС) - отходы производства окислительной демеркаптанизации пропан-центановой фракции C3-C5 при следующем соотношении компонентов, мас.%: смесь низкомолекулярных диалкилдисульфидов C2-C8 93-99,9; алкилмеркаптаны - остальное. Предлагаемый одорант получают смешением алкилмеркаптанов и смеси СНДС. Предварительно получают неочищенные алкилмеркаптаны - этил-, пропил-, бутил-, амил меркаптаны взаимодействием соответствующих алифатических спиртов с сероводородом в жидкой фазе в присутствии катализатора - серной кислоты, которые затем смешивают со смесью СНДС в количестве 93-99,9 мас.% в различных соотношениях компонентов.The invention relates to the chemical and gas industry, namely to the odorants used for the odorization of liquefied natural, refinery and organic compounds that do not have the smell. The essence of the invention lies in the fact that the odorant for liquefied hydrocarbon gases contains alkyl mercaptans and additionally a mixture of low molecular weight C 2 -C 8 dialkyl disulfides (SNDS) —products of the oxidative demercaptanization of the propane-cents fraction C 3 -C 5 in the following ratio of components, wt.% a mixture of low molecular weight dialkyl disulfides C 2 -C 8 93-99,9; alkyl mercaptans - the rest. The proposed odorant is obtained by mixing alkyl mercaptans and a mixture of CNDS. Crude alkyl mercaptans — ethyl, propyl, butyl, amyl mercaptans — are obtained in advance by reacting the corresponding aliphatic alcohols with hydrogen sulfide in the liquid phase in the presence of a catalyst — sulfuric acid, which are then mixed with a mixture of CHDS in an amount of 93-99.9% by weight in various component ratios.
