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.

标题 :Synthesis of sulfonic acids and carboxylic acid ester derivatives thereof
发明人：MCGEE DENNIS E; HALLEN TED S
权利人:UNION OIL CO
摘要:Hydroxy sulfonic acids in general and isethionic acid (2-hydroxy ethyl sulfonic acid) in particular can be prepared at 99+% purity and good yields by the selective oxidation of a precursor hydroxy mercaptan with hydrogen peroxide. The resulting product is pure enough to be used directly in the synthesis of sulfo-acrylic esters which are finding considerable use as stabilizers in producing vinylidene chloride copolymers used for FDA approved packaging films.
