This invention relates to a process for preparing a sulfurized composition comprising the steps of preparing a mixture comprising (a) a fatty acid or ester, and (b) an olefin having from about 6 to about 30 carbon atoms, and reacting the mixture with sulfur and hydrogen sulfide in the presence of a catalyst and under superatmospheric pressure, wherein the mixture contains from about 10 to about 90 parts by weight of (a) and from about 10 parts to about 80 parts by weight of (b), and wherein from about 10% to about 70% of the sulfur is from hydrogen sulfide. The invention also relates to a sulfur composition comprising a hydrocarbyl sulfide, wherein from about 20% to about 90% of the hydrocarbyl groups are derived from a fatty acid or ester and from about 10% to about 80% of the hydrocarbyl groups are derived from an olefin having from about 6 to about 30 carbon atoms, wherein the hydrocarbyl sulfide contains from about 8% to about 15% sulfur, and has a neat ASTM color of less than about 4.5.
本发明涉及一种制备硫化组合物的工艺,包括以下步骤:制备包含(a) 脂肪酸或脂肪酸酯和(b) 具有约 6 至约 30 个碳原子的烯烃的混合物、在催化剂存在下并在超大气压下,使该混合物与硫和硫化氢反应,其中混合物含有按重量计约 10 至约 90 份的(a)和按重量计约 10 至约 80 份的(b),其中约 10%至约 70%的硫来自硫化氢。本发明还涉及一种包含烃基硫化物的硫组合物,其中约 20%至约 90%的烃基衍生自脂肪酸或酯,约 10%至约 80%的烃基衍生自具有约 6 至约 30 个碳原子的烯烃,其中烃基硫化物含有约 8%至约 15%的硫,其纯净的 ASTM 色度小于约 4.5。
