Abstract

PROCESSO PARA REDUÇçO DO TEOR DE CLORO HIDROLISÁVEL EM ISOCIANATOS ORGÂNICOS OU EM MISTURAS DE ISOCIANATOS ORGÂNICOS, EMPREGO DE ISOCIANATOS. A presente invenção se refere a um processo para uma eliminação considerável de compostos de cloro de isocianatos orgânicos ou de misturas de isocianatos orgânicos, colocando-se o isocianato ou a mistura de isocianatos em contato com uma corrente de gás inerte contendo água ou com um material orgânico que tem efeito trocador de cátions. O processo permite uma eliminação suave de compostos contendo cloro dos isocianatos e se presta especialmente bem para isocianatos sensíveis à temperatura.
