The invention related to a process for the preparation of a bismercaptodiether by reacting a polysulfide with a monothiol in the presence of a base and to a process for the depolymerization of a polysulfide by reacting said polysulfide with a monothiol in the presence of a base. These processes enable the preparation of bismercaptodiethers without inorganic salt formation.
该发明涉及一种通过在碱的存在下将多硫化物与单硫醇反应制备双巯基二醚的方法,以及一种通过在碱的存在下将多硫化物与单硫醇反应进行多硫化物的去聚合的方法。这些方法使得可以制备双巯基二醚而无需形成无机盐。
