PROCEDE DE FABRICATION DE (METH)ACRYLATE DE DIALKYLAMINOALKYLE

Process for the manufacture of dialkylaminoalkyl (meth)acrylates (I) of formula: H2C=C(R1)-C(O)-O-A-N(R2)(R3) R1 being a hydrogen atom or a methyl radical, A being a linear or branched alkyl radical containing 1 to 5 carbon atoms, and R2 and R3, which are identical or different from each other, are an alkyl radical containing 1 to 5 carbon atoms, or an aryl group, or R2 and R3 form a cyclic alkyl radical, in which ethyl (meth)acrylate is reacted with an aminoalcohol (II) of formula (R3)(R2)N-A-OH, A being a linear or branched alkyl radical containing 1 to 5 carbon atoms, in the presence of a polymerization inhibitor, at a temperature of between 20 DEG and 120 DEG C. and at a pressure equal to or lower than atmospheric pressure, in a molar ratio of ethyl (meth)acrylate to aminoalcohol (II) of between 1.5 and 5, in the presence of tetraethyl titanate, the azeotropic mixture of ethyl (meth)acrylate and ethanol is removed during the reaction, and the dialkylaminoalkyl (meth)acrylate (I) obtained is isolated at the end of reaction.
