标 题 :One pot synthesis of urea (meth)acrylates
发明人：BESTGEN SEBASTIAN; BEYER SILVIA
权利人:EVONIK OPERATIONS GMBH
摘要:A one-pot synthesis of polymerizable and acyclic urea (meth)acrylates, preferably mono(meth)acrylates, can be performed via in-situ synthesis of urea alcohols or amines followed by direct reaction with a (meth)acrylate reactive diluent. The urea alcohol/amine is obtained from isocyanates and alcohols, amines, or hydroxyamines. Subsequently, the reaction with the (meth)acrylate reactive diluent takes place and the urea (meth)acrylate is directly obtained either in solution with the reactive diluent, or as a pure material after removal of the reactive diluent.

标题:Process for synthesis of isobornyl (Meth) acrylate
发明人：KNEBEL JOACHIM; SAAL DORIS
权利人:ROEHM GMBH
摘要:The present invention relates to processes for synthesis of isobornyl (meth)acrylate by reacting camphene with (meth)acrylic acid in the presence of sulfuric acid and at least one compound having inhibiting action. Aqueous sulfuric acid with an acid concentration in the range of 65 to 85 wt % is used. Isobornyl (meth)acrylate can advantageously be distilled from a mixture containing sulfuric acid in the presence of 2,6-di-tert-butyl-alpha-(dialkylamino)-p-cresol.
