Abstract

The present invention discloses a heavy oil emulsifying viscosity reducer synthesis process based on sulfonation degree control. The heavy oil emulsifying viscosity reducer synthesis process comprises: (1) carrying out a condensation reaction of octyl phenol polyoxyethylene ether and formaldehyde; (b) carrying out a sulfonation reaction of a co-polycondensate and concentrated sulfuric acid, and controlling the sulfonation degree during the reaction process at 0.70-0.95; and (c) neutralizing to prepare the heavy oil emulsifying viscosity reducer. According to the present invention, the heavy oil emulsifying viscosity reducer is successfully synthesized, the synthesis efficiency is high, the synthesis cost is low, and by controlling the sulfonation degree during the reaction process, the product stability is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a synthesis process of a thick oil emulsification viscosity reducer based on controlling the degree of sulfonation. Background technique [0002] There are many types of viscosity reducers. Among them, the effect of polyether viscosity reducer is better. ME dryness reducer can play the following roles: (1) Reduce the paste viscosity, adding 1 part of ME viscosity reducer per 100 parts of PVC paste resin can reduce the paste viscosity by 1 / 3~1 / 2. For high-speed coating, slush molding, dipping, dipping and other molding processes that require low-viscosity PVC paste, adding a viscosity reducer is an effective method for reducing viscosity. (2) The effect of reducing the amount of plasticizer on reducing the viscosity of the paste, the effect of 1 part of ME viscosity reducer is equivalent to 6-8 parts of DOP. Therefore, for products that require higher h...
