[0005] Chinese invention patent (CN102333576A) discloses the use of a non-dendritic high-functionality hyperbranched polyester and polycarbonate as a demulsifier for separating crude oil emulsions. The non-dendritic high-functionality hyperbranched polyester and polycarbonate Carbonates are obtainable by the reaction of at least one aliphatic, cycloaliphatic, araliphatic or aromatic dicarboxylic acid or their derivatives, or an organic polycarbonate, and at least one x-membered aliphatic aliphatic, cycloaliphatic, araliphatic or aromatic alcohols having more than two hydroxyl groups, where x is a number greater than 2, and at least one saturated or unsaturated alcohol having an average of 1 to 40 alkylene oxide units C 2 -C 30 Fatty acid amide alkoxylates of fatty acid amides, but the composition of the above-mentioned non-dendritic high-functionality hyperbranched polyesters and polycarbonates is relatively complex

[0023] Preparation of Polyether Hyperbranched Polymers

[0024] Get 5g hyperbranched polyglycidol, dissolve and disperse in an appropriate amount of DMSO (V DMSO :m HPG =9), add 1g of catalyst 4-dimethylaminopyridine, under the protection of nitrogen, add 50mL of glycidyl methacrylate (GMA) dropwise, stir vigorously at room temperature for 5h, then pour the product into 100mL of ether After stirring for 20 minutes, it can be observed that the light yellow liquid sinks to the lower layer. After repeating twice, the upper layer of ether is discarded to obtain a viscous liquid. The light yellow liquid obtained after removing the ether by rotary evaporation is HPG-MA.

Abstract

The invention relates to application of polyether hyperbranched polymers as a demulsifier. The center of the polyether hyperbranched polymers is a polyether structure, and the terminal group comprises hydrophilic hydroxy group and hydrophobic double bond. The number-average molecular weight distribution of the polyether hyperbranched polymers is 2000-8000. When the polyether hyperbranched polymers are used as the demulsifier, the oil-water separation rate of the emulsion is increased, the demulsification efficiency of the polyether hyperbranched polymers is enhanced, and the application range of the polyether hyperbranched polymers is widened.

Description

technical field [0001] The invention relates to the technical field of petroleum additives, in particular to the application of a polyether hyperbranched polymer as a demulsifier. Background technique [0002] In 1988, Kim and Webster (Journal of the American Chemical Society, 1990, 112:4592-4593.) jointly proposed the term hyperbranched polymers (hyperbranched polymers) to define those polymers whose structures are different from those of dendrimers. Similar to dendrimers, hyperbranched polymers are a type of highly branched macromolecular substances with 3D and topological structures. The highly branched structure endows them with unique properties such as excellent dispersion effect, low viscosity and high rheology. , the end contains abundant functional groups to provide good conditions for functionalization, so it has become one of the research hotspots in the field of polymers, and has been applied in the fields of biomedicine, petrochemicals, supramolecular self-assem...
