Abstract:
There is provided herein a demulsifying composition comprising at least one polyorganosiloxane compound having the general formula (I): M1aM2bD1cD2dT1eT2fQg (I) wherein: M1=R1R2R3SiO1/2, M2=R4R5RLSiO1/2, D1=R6R7SiO2/2, D2=R8RLSiO2/2, T1=R9SiO3/2, T2=RLSiO3/2, Q=SiO4/2, where R1, R2, R3, R4, R5, R6, R7, R8 and R9 are each independently chosen from monovalent alkyl, aryl or aralkyl hydrocarbon radicals, or chosen from RP; RP is a monovalent polyether radical independently of the general formula (II): —(CnH2n)—O—(C2H4O)o—(C3H6O)p—(C4H8O)q—R10 (II) RL is a monovalent radical independently chosen from the general formula (III): —X—O—(C2H4O)r—(C3H6O)s—(C4H8O)t—{C(O)CuH2uO}v—R11 (III) There is also provided herein a method for separating emulsions comprising combining the components of the demulsification composition into a mixture; allowing the mixture to separate into at least two phases and separating said at least two phases from each other.
