Abstract

DESEMULSIFICANTE, DESEMULSIFICANTE DE POLI (TETRAIDROFURANO) ,DESEMULSIFICANTE DO TIPO áGUA-EM-óLEO E MéTODO PARA DECOMPOR UMA EMULSãO QUE COMPREENDE óLEO E áGUA. A presente invenção apresenta desemulsificantes ambientalmente amigáveis para a decomposição de aplicações de óleo de petróleo. As formulações de desemulsificação da presente invenção são biodegradáveis e são de baixa toxicidade. Os desemulsificantes incluem um glicol de poli(tetrametileno) e um copolímero de glicol de alquileno ligado ao glicol de poli(tetrametileno) por um agente de acoplamento difuncional.
