Abstract

Patente de Invenção: <B>"PROCESSO PARA PREPARAçãO DE ESTABILIZADORES DE BAIXO CLORETO"<D>. Um processo para a preparação de uma mistura estabilizadora contendo uma quantidade baixa de cloreto compreendendo: a) 50 a 80% em peso de difosfonito de tetracis(2,4-di -terc -butil-fenil)-bifenileno e seus isómeros, b) 5 a 25% em peso de um monofosfito de bis(2,4-di-terc -butil-fenil)-bifenileno e seus isómeros, e c) 5 a 25 % em peso de um fosfito de tris(2,4-di -terc -butilfenil), e onde a soma dos componentes (a), (b) e (c) não é maior do que 100% em peso, reagindo-se a bifenila sob a condição de Friedel-Crafts com tricloreto de fósforo e tricloreto de alumínio e reagindo-se a mistura de produto com 2,4-di -terc-butil-fenol na presença de uma amina terciária ou uma amina aromática e um solvente, separando-se as duas camadas formadas, cujo processo compreende tratar a camada solvente com água, uma base e um dessecante, separando-se o precipitado da solução contendo a mistura estabilizadora e evaporando-se o solvente.
