摘要:The present invention provides a route for synthesizing monofunctional thiuram compounds that is safe, environmentally friendly, and cost effective. This method specifically involves synthesizing a monofunctional thiuram by (1) reacting a tetraorganylthiuram disulfide with an organyl mercaptan to produce the monofunctional thiuram and a dithiocarbamate metal salt or a dithiocarbamate metalloid salt under basic conditions, (2) separating the monofunctional thiuram in an organic phase from the dithiocarbamate metal salt or the dithiocarbamate metalloid salt in an aqueous phase, and (3) recovering the monofunctional thiuram from the aqueous phase. The monofunctional thiuram compounds made in accordance with this invention are of particular value as accelerators for use in the vulcanization of rubber. The use of these monofunctional thiuram compounds as accelerators provides good cure rates and as well as good scorch safety.

标 题 :Polysulfide polyols, their production and use in the synthesis of polyurethanes
发明人：BALBO BLOCK MARCO; RHUDY KEVIN; FLECKENSTEIN CHRISTOPH
权利人:BASF SE
摘要:The present invention relates to sulfur containing polyols, a process for their production by reaction of at least one unsaturated alcohol A with elemental sulfur, wherein the unsaturated alcohol A has only one carbon-carbon double bond-unsaturation per molecule. The sulfur containing polyols are used in the production of polyurethanes, in particular rigid foam polyurethanes, for high-temperature pipe insulation applications.
