Abstract

Patente de Invenção:<B>"PROCESSO PARA PREPARAçãO DE PRóACORDES DE FRAGRâNCIA DE BETA-CETOéSTER A PARTIR DE 1,3-DIOXANO-4,6-DIONAS"<D>. A presente invenção refere-se a processos para preparar próacordes de fragrância de <225>-cetoéster a partir de unidades acila ativadas, 1,3-dioxan-4,6-dionas e álcoois matéria-prima de fragrância. A primeira etapa do processo divulgado envolve contatar uma unidade acila ativada, preferivelmente um cloreto ácido, com uma 1,3-dioxan-4,6-diona, um exemplo do qual é ácido de Meldrum, para formar uma 2-acila 1,3-dioxan-4,6-diona que reage então com um álcool matéria-prima de fragrância para formar o pró-acord de fragrância de <225>-cetoéster final. Os pró-acordes de fragrância de <225>-cetoéster resultante são adequados para uso em detergentes de lavanderia, produtos de cuidados pessoais, e outras formulações em que materiais de fragrância estéticos são empregados.
