Embodiment 1

[0035] Under the protection of nitrogen, 100g of phenyl hydrogen-containing silicone oil (the mass percentage of hydrogen is 0.5%, the mass percentage of benzene is 20%, the viscosity is 25mpa s), 750g of allyl alcohol polyether and 0.0255g of catalyst are added into the 1. In a 250mL four-neck flask with a stirrer, the temperature was raised to 100°C under stirring, and the reaction was carried out at this temperature for 7h. Then, the temperature was naturally lowered to room temperature to obtain polyether-modified phenyl hydrogen-containing silicone oil.

Embodiment 2

[0037] Under the protection of nitrogen, add 100g of phenyl hydrogen-containing silicone oil (0.5% by mass percentage of hydrogen, 20% by mass of benzene, and a viscosity of 25mpa s), 825g of allyl alcohol polyether and 0.02775g of catalyst, and add it with a thermometer 1. In a 250mL four-necked flask with a stirrer, the temperature was raised to 110° C. under stirring, and the reaction was carried out at this temperature for 8 hours. Then, the temperature was naturally lowered to room temperature to obtain polyether-modified phenyl hydrogen-containing silicone oil.

Embodiment 3

[0039] Under the protection of nitrogen, 100g of phenyl hydrogen-containing silicone oil (0.5% by mass percentage of hydrogen, 20% by mass of benzene, viscosity of 25mpa s), 900g of allyl alcohol polyether and 0.03g of catalyst were added to the 1. In a 250mL four-neck flask with a stirrer, the temperature was raised to 120°C under stirring, and the reaction was carried out at this temperature for 9h. Then, the temperature was naturally lowered to room temperature to obtain polyether-modified phenyl hydrogen-containing silicone oil.

Abstract

The invention relates to polyether modified phenyl hydrogen-containing silicone oil and a preparation method thereof. According to the invention, under nitrogen protection, an isopropyl alcohol solution of chloroplatinic acid, the phenyl hydrogen-containing silicone oil and polyether are added in a reaction vessel, the above components are subjected to a reaction for 7-10 hours at temperature of 100-130 DEG C to obtain the polyether modified phenyl hydrogen-containing silicone oil; wherein, a mol ratio of phenyl hydrogen-containing silicone oil to polyether is 1:(1-1.3). According to the invention, platinum is employed as a catalyst, the provided preparation method realizes good performance of the modified silicone oil, and the method for the hydrogen-containing silicone oil has the advantages of simple operation, low cost and high efficiency, a purpose of large-scale production requirement can be satisfied, the employed hydrogen-containing silicone oil can save preparation steps and can reach the purpose of enhancing thermostability of polysiloxane.

Description

technical field [0001] The invention relates to a demulsifier used for heavy oil in oil fields, in particular to a polyether modified phenyl hydrogen-containing silicone oil and a preparation method thereof. Background technique [0002] Silicone surfactant is a new type of surfactant developed with new silicone materials. The Si-O-Si link in the main chain of its structure has a stronger hydrophobic effect than traditional carbon chain surfactants. It thus has an excellent ability to reduce surface tension. Among them, polyether-modified silicone surfactants are the most widely studied and have the most product types, which are widely used in cosmetic additives, polyurethane foam stabilizers, fabric finishing agents, defoamers, demulsifiers and coatings. [0003] The main synthesis method of polyether modified silicone oil is to use the Si-H bond and the unsaturated double bond between the hydrosilicon addition reaction, the catalyst used is mostly complexes of noble metal...
