Abstract

Patente de Invenção: <B>"RECICLAGEM DE éSTER ALQUìLICO INFERIOR EM SìNTESE DE POLIéSTER DE POLIOL DE áCIDO GRAXO"<D>. Processo para a síntese de poliésteres de poliol de ácido graxo o qual inclui as etapas de reagir um excesso de éster alquílico inferior com poliol para esterificar os grupos hidroxila dos mesmos e formar o poliésteres de poliol de ácido graxo, separação de pelo menos uma porção do éster alquílico inferior que não reagiu, a partir do poliéster poliol de ácido graxo, e reciclagem do éster alquílico inferior separado que não reagiu, para posterior reação com o poliol ou poliol parcialmente esterificado. A reciclagem de éster alquílico inferior é substancialmente livre de produtos da reação de degradação de éster alquílico inferior, tais como carbonilas e ácidos graxos livres.
