5669(2) ABSTRACT OF THE DISCLOSURE Demulsifying process Emulsions of oil and water are broken by treating them with a demulsifier which is a polysiloxane polyalkylene oxide copolymer in which the polyalkylene oxide segment is composed of random ethylene oxide and propylene oxide units. The demulsifier is particularly useful in breaking emulsions of water in crude oil which are normally difficult to separate and in breaking emulsions at relatively low temperatures, e.g. 30° to 45°C.
