COMPOSITE FOR REGULATION OF VISCOSITY OF HIGH-VISCOSITY OILS AND AQUEOUS-OILY EMULSION Russian patent published in 2003 - IPC

FIELD: organic chemistry. SUBSTANCE: invention relates to composites used in output, transporting and preparing for processing high-viscosity oils and oily emulsions. Composite for regulation of viscosity comprises the following substances as block-copolymer of ethylene oxide and propylene oxide, wt.-%: glycols-base block-copolymer of the general formula: H(C₂H₄O)_n(C₃H₆O)_mOAO(C₃H₆O)_m(C₂H₄O)_nH wherein A is C₂H₄ or -C₃H₆; n = 14-16; m = 24-27 with molecular mass 4300 Da or ethylenediamine-base block-copolymer of the general formula: wherein n = 6-7; m = 14-15 with molecular mass 5000 Da, 25-75; synthetic fatty alcohols-base block-copolymer of ethylene oxide of the general formula: C_nH_n+1O(C₂H₄O)_mH wherein n = 10-20; m = 3-20, or mixture of higher fatty alcohol polyethylene esters, 25-75. In mixing the composite with oil or oily emulsion a solvent is added to composite in the mass ratio composite : solvent = from 2:1 to 1:5. Lower aliphatic alcohol or aromatic hydrocarbon is used as a solvent. EFFECT: enhanced effectiveness of alternation of oily emulsions viscosity. 2 cl, 4 tbl, 30 ex
