Abstract

processo para a preparação de (met) acrilatos, éster do ácido (met) acrílico, uso de ésteres do ácido (met) acrílico, e,uso de dispersões. a invenção refere-se a um método para a produção de (met) acrilatos de misturas de álcool-c~ 17~ por meio de conversão de ácido (met) acrílico com uma mistura de álcool-c~ 17~, na presença de pelo menos um catalisador ácido e pelo menos um inibidor de polimerização e na presença de um solvente formando um azeótropo com água, em que a esterificação é realizada num reator com um evaporador de circulação, o azeótropo é destilado para fora e condensado, o condensado degrada-se em uma fase orgânica e aquosa e, em que a mistura de álcool-c~ 17~ compreende um nível médio de ramificação (índice iso) de 2,8 a 3,7.process for the preparation of (meth) acrylates, (meth) acrylic acid ester, use of (meth) acrylic acid esters, and use of dispersions. The invention relates to a method for the production of (meth) acrylates from C17-alcohol mixtures by converting (meth) acrylic acid with a C17-alcohol mixture in the presence of at least least one acid catalyst and at least one polymerization inhibitor and in the presence of a solvent forming an azeotrope with water, where esterification is carried out in a reactor with a circulating evaporator, the azeotrope is distilled out and condensed, the condensate degrades. in an organic and aqueous phase and wherein the C17-17 alcohol mixture comprises an average branch level (iso index) of 2.8 to 3.7.
