标 题:Method for the synthesis of (meth)acrylic esters catalysed by a polyol titanate
发明人：PAUL JEAN-MICHEL
权利人:PAUL JEAN-MICHEL; ARKEMA FRANCE
摘要:The subject of the invention is a method for the synthesis of (meth)acrylic esters by transesterification in the presence of a catalyst corresponding to the formula [(R′O) 3 Ti] x R″ in which R′ is a linear or branched alkyl radical having from 2 to 8 carbon atoms which may contain heteroatoms or R′ is a phenyl radical, R′ is a polyfunctional radical, originating from a polyol R′(OH) x comprising x alcohol functional groups and x is an integer ranging from 2 to 6. The method according to the invention is particularly well suited to the synthesis of dialkylaminoalkyl (meth)acrylates from methyl (meth)acrylate and a dialkylaminoalcohol.

标题 :Enzymatic synthesis of acetoacetate esters and derivatives
发明人：HENDERSON SAMUEL T
权利人:HENDERSON SAMUEL T; ACCERA INC
摘要:In one embodiment, the present invention includes a method for the synthesis of an ester derivative of acetoacetate. The method includes providing a first ester of acetoacetate and providing an alcohol. The method further includes combining the first ester of acetoacetate and the alcohol in the presence of an enzyme capable of transesterification in a non-aqueous solvent to form the ester derivative of acetoacetate. The method results in the formation of the ester derivative of acetoacetate, which, in one embodiment, is monoacetoacetin.
