    IPC: C07D327/04

    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 for preparing coatings or sealed materials using a coating composition or a sealant that contains a first component and a second component. The first component includes a compound A) with at least one five-membered cyclic monothiocarbonate group. The second component includes a compound B) with at least one amino group. The at least one amino group can be a primary or secondary amino group or blocked primary or secondary amino group. Compounds A) or B) may additionally have at least one polymerizable, ethylenically unsaturated group. The coating composition or sealant may further include a compound C) with at least one polymerizable, ethylenically unsaturated group.
