The present invention relates to a process for the preparation of bis-(2-hydroxyethyl)-disulfide by oxidizing 2-mercaptoethanol with oxygen in a reaction mixture comprising at least one ho- mogeneously distributed iron comprising salt or complex as catalyst and at least one tertiary amine, to bis-(2-hydroxyethyl)-disulfide, obtainable with the process, and to the use of this bis- (2-hydroxyethyl)-disulfide as intermediate in the manufacture of chemical compounds, such as lubricant additives and in the tertiary oil recovery.
本发明涉及一种制备双-(2-羟乙基)-二
硫化物的方法,该方法通过将
2-巯基乙醇与
氧气在反应混合物中氧化,其中该混合物包括至少一种均匀分布的
铁盐或配合物作为催化剂和至少一种三级胺,得到的产物为双-(2-羟乙基)-二
硫化物。本发明还涉及将该双-(2-羟乙基)-二
硫化物作为
化学化合物的中间体用于制造润滑剂添加剂和三级油回收等方面的用途。
