Abstract: 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.

Abstract: A process prepares a prepolymer containing a urethane group and a curable silicon-functional group, or a prepolymer of formula (IV), The prepolymer may be cured to a cross-linked polymer by ambient moisture and is therefore suitable for use as a component in a one-component sealant or adhesive composition.

Abstract: 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.

Abstract: Provided is a process for the preparation of a compound with at least one five-membered cyclic monothiocarbonate group. A compound C1 with at least one halohydrin group is used as starting material. Compound C1 is reacted with phosgene or an alkyl chloroformate to give an adduct C2. The adduct C2 is reacted with a compound that includes anionic sulfur to obtain the compound with at least one five-membered cyclic monothiocarbonate group.

Abstract: 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.
