摘要： A process synthesizes a compound with at least one alkylene group and at least one thiol or thiolate group. The process involves reacting a compound with at least one five-membered cyclic monothiocarbonate group with a starter selected from a compound with at least one thiol group, from a compound with at least one hydroxy group, or from a basic inorganic composed; to obtain a compound with at least one alkylene group and at least one thiol or thiolate group and carbon dioxide.

摘要： A process prepares a cross-linked polymer containing urethane groups and silicon atoms. Starting materials of the process include a compound A) with a five-membered cyclic monothiocarbonate group, a compound B) with an amino group, selected from primary or secondary amino groups or blocked amino groups, and optionally, a compound C) with at least one functional group that reacts with a group —SH. One of the compounds contains a silicon-functional group. In one example of the process, compounds A) and B), and optionally C), are then reacted under exclusion of water to obtain a polymer with curable silicon-functional groups. The polymer is applied to a surface, gap, or a three-dimensional template. The silicon-functional groups are cured with ambient water. The polymer contains 0.001 to 0.3 mol of silicon per 100 g of the polymer.

摘要： A process for the purification of organic sulfur compounds involves bringing the organic sulfur compounds, in a liquid phase, into contact with an oxide of a metal from groups VIIb or VIIIb and an oxide of a metal from groups Ia to IIIa of the periodic system, or alternatively, with a mixed-oxide thereof; for a contact period of at least 1 minute. Afterwards, the oxides and the organic sulfur compounds are separated.
