Synthetic process of alkylphenol polyoxyethylene ether sodium acetate with reaction time controlled

Abstract

The invention discloses a synthetic process of alkylphenol polyoxyethylene ether sodium acetate with reaction time controlled. The synthetic process includes the following steps: (A) assembling a stirrer and a condenser pipe, and arranging a water bath pot; (B) preparing OP-10, chloroacetic acid and NaOH; (C) pouring the OP-10 into a reaction container, placing the reaction container in water bath, and starting the stirrer; (D) slowly adding the weighed powdery NaOH, performing alkalization at room temperature and slowly dropwise adding the chloroacetic acid in certain amount, and controlling the reaction time to be 5-9 h; (E) when the reaction is finished, regulating the temperature of the water bath to evaporate acetone, thereby obtaining a beige thick substance; and (F) adding a prepared hydrochloric acid solution to neutralize the beige thick substance, heating the beige thick substance to separate an organic phase from a water phase, and collecting the organic phase to obtain the target product. The synthetic process can be used for preparing the alkylphenol polyoxyethylene ether sodium acetate quickly, is high in efficiency and low in cost, and can increase the conversion rate of the reaction by controlling the reaction time during the synthetic process.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a synthesis process of alkylphenol polyoxyethylene ether sodium acetate with controlled reaction time. Background technique [0002] Alkylphenol polyoxyethylene ether is one of the main varieties of polyoxyethylene nonionic surfactants. It has the advantages of strong permeability, high detergency, good compatibility, and rapid dissolution. However, its ability to degrease skin and hair Stronger, more irritating to the skin, and weaker in foaming power, and soap (RCH2COONa) has poor water solubility and hard water resistance, and is used as an active raw material for daily cleaning products. In the current synthesis process method of alkylphenol polyoxyethylene ether sodium acetate, the process flow is not easy to implement, the purity of the finished product is low, the single-pass conversion rate of the reactant is low, the production process is complic...
