Abstract

Patente de Invenção:<B>"PROCESSO PARA PREPARAçãO DE éSTERES MACROCìCLICOS"<D>. A invenção refere-se a um processo para preparação de ésteres macrocíclicos da fórmula geral Fórmula I na qual <MU> m <MV> representa um número inteiro de 6 até 14 e <MU> n <MV> representa um número inteiro de 2 até 6, por ciclização de bis(glicol) ésteres de ácido dicarboxílicos da fórmula geral Fórmula II HO-(CH~ 2~)~ n~-O-CO-(CH~2~)~ m~-CO-O-(CH~ 2~)~ n~-OH na qual <MU> m <MV> e <MU> n <MV> têm significados indicados na fórmula I, sendo que (b) opcionalmente até 100% em peso, relativo ao éster II, dos ésteres relativos ao éster II tendo em vista os seus elementos constituintes, de fórmula geral Fórmula III H[O-(CH~2~)~ n~-O-CO-(CH~2~)~ m~-CO]~ x~-O-(CH~ 2~)~ n~-OH, Fórmula IV H[O(CH~ 2~)~ n~-O-CO-(CH~ 2~)~ m~-CO]~ x~-OH e/ou Fórmula V HO-CO-(CH~ 2~)~ m~-CO-[O-CH~ 2~)~ n~-O-CO-(Ch~ 2~)~ m~-CO]~ x~-OH, nas quais <MU> m <MV> e <MU> n <MV> têm o mesmo valor indicado e <MU> x <Mu> representa um número inteiro >1 assim como,(c) um glicol da fórmula geral Fórmula VI HO-(CH~2~)~ n~-OH na qula <MU> n <MV> tem o mesmo valor numérico que nas fórmulas I até V, na quantidade de 1 até 50 vezesa quantidade molar, relativa ao éster II e aos elementos constituintes do ácido dicarboxílico dos ésteres III até V, e (d) um meio inerte de reação de alto ponto de ebulição no qual aquece-se 0,1 até 20 vezes, a quantidade em peso, relativa à soma das quantidades em peso dos ésteres II e III até V, na presença de (e) catalisador são aquecidos em um vaporizador com grande superfície, a temperatura de 150 até 350°C a uma pressão reduzida de cerca de 0,1 até cerca de 500 mbar, sendo que origina-se um éster I macrocíclico com liberação de glicol, que é destilado juntamente com glicol IV e obtido por condensação.
