Abstract
"PROCESSO PARA PREPARAçãO DE éSTERES DE áCIDO HIDROXIFENILCARBOXìLICO". A presente invenção refere-se a um processo para preparação de compostos da fórmula (I) na qual R~ 1~ e R~ 2~, independentemente um do outro, significam C~ 1~-C~ 8~alquila, ciclopentila ou ciclohexila, n significa 1, 2 ou 3, preferivelmente, 2, n significa um número inteiro de 1 a 30, e R~ 3~ significa um radical de valor n de C~ 4~-C~ 30~-alquila linear ou ramificado, que está opcionalmente interrompido por um ou mais átomos de oxigênio, ou (para n = 1-12), um radical de valor n de C~ 5~-C~ 12~-cicloalquila ou um radical R~ 4~-[NR~ 5~-C~ m~H~ 2m~-]~ p~, R~ 4~ significa hidrogênio, um radical de valor n de C~ 4~-C~ 30~-alquila linear ou ramificado, que está opcionalmente interrompido por um ou mais grupos -NR~ 5~-, ou (para n = 1-12), um radical de valor n de C~ 5~-C~ 12~cicloalquila, R~ 5~ significa, independentemente um do outro, hidrogênio ou metila ou -C~ m~H~ 2m~-, preferivelmente, hidrogênio, e p corresponde ao número de grupos -[NR~ 5~-C~ m~H~ 2m~-], que produz n radicais -C~ m~H~ 2m~- por molécula, por reação de um composto da fórmula (II) na qual R significa C~ 1~-C~ 3~-alquila, com um composto da fórmula (III) R~ 3~(OH)~ n~ (III), na qual R~ 3~ e n têm os significados indicados acima, caracterizado pelo fato de que a reação se dá a um valor de acidez (pH) praticamente neutro e na presença de pelo menos um sal alcalino de um ácido carboxílico orgânico, dissolvido ou suspenso na mistura de reação, ou uma mistura desses sais alcalinos, sendo que (I) esse sal alcalino está formado de um cátion alcalino e um ânion de um ácido carboxílico orgânico e (ii) o ácido carboxílico orgânico é pelo menos parcialmente volátil sob as condições de reações usadas. Sais alcalinos preferidos são formiato alcalino e acetato alcalino.
