    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.

    Abstract: The invention relates to a process for producing 4,4′-dichlorodiphenyl sulfoxide comprising: (I) reacting thionyl chloride, chlorobenzene and aluminum chloride in a molar ratio of thionyl chloride:chlorobenzene:aluminum chloride of 1:(6 to 9):(1 to 1.5) at a temperature in the range from 0 to below 20° C., forming an intermediate reaction product and hydrogen chloride; (II) mixing aqueous hydrochloric acid and the intermediate reaction product at a temperature in the range from 70 to 110° C. to obtain an organic phase comprising 4,4′-dichlorodiphenyl sulfoxide and an aqueous phase; (III) cooling the organic phase comprising the 4,4′-dichlorodiphenyl sulfoxide to a temperature below the saturation point of 4,4′-dichlorodiphenyl sulfoxide to obtain a suspension comprising crystallized 4,4′-dichlorodiphenyl sulfoxide; (IV) solid-liquid-separation of the suspension to obtain a residual moisture containing solid 4,4′-dichlorodiphenyl sulfoxide comprising crystallized 4,4′-dichlorodiphenyl sulfoxide and mother liquor.
