Abstract

"PURIFICAçãO DE COMPOSTOS CONTENDO SILICONE POR EXTRAçãO COM FLUIDO SUPERCRìTICO". A presente invenção refere-se a um processo para a purificação de compostos contendo silicone via extração com fluido supercrítico. Especificamente, a presente invenção refere-se a um processo compreendendo as etapas de colocar pelo menos um composto contendo silicone em contato com um fluido supercrítico tendo uma densidade entre cerca de 0,2 e cerca de 0,8 g/ml, reduzir a referida densidade para que sejam formadas duas fases, uma primeira fase compreendendo o referido pelo menos um composto contendo silicone e uma segunda fase compreendendo pelo menos uma impureza, e separar a referida segunda fase da referida primeira fase.
