Embodiment 1

[0022] The preparation of acrylic acid 2-butyl octanol: take respectively acrylic acid and 2-butyl octanol that the molar ratio is 1.2:1, 2-butyl octanol, hydroquinone, SO 4 2- / M x o y Add the type solid superacid catalyst and solvent toluene into the three-necked flask, stir well, and raise the temperature to 110°C. Wherein the consumption of hydroquinone is 0.6% of the total weight of acid and alcohol, SO 4 2- / M x o y The consumption of type solid superacid catalyst is 1.0% of the total weight of acid and alcohol, and the consumption of solvent toluene is 30% of the total weight of acid and alcohol. Put acrylic acid into a constant pressure separatory funnel, add it dropwise into a three-necked flask, stir well, and the reaction time is 3 hours. After the reaction was over, the solvent toluene was evaporated by rotary evaporation, filtered under reduced pressure, and then washed with 10% NaOH solution and saturated Na 2 SO 4 Solution 500ml washes the filtrate succ...

Abstract

The invention provides an acrylic acid Guerbet alcohol ester and a preparation method and application thereof, and belongs to the field of an acrylic acid alcohol ester and preparation thereof. According to the invention, acrylic acid and Guerbet alcohol are adopted as raw materials; a catalyst is toluene sulfonic acid or SO4<2-> / MxOy type solid superacid; and after full reaction, rotary steaming, filtering, washing and drying are preformed to obtain liquid acrylic acid Guerbet alcohol ester. The method is simple to operate, higher in esterification rate, economical, applicable and convenient for industrial production. The acrylic acid Guerbet alcohol ester is a novel high-molecular monomer; and the acrylic acid Guerbet alcohol ester, a homopolymer of the acrylic acid Guerbet alcohol ester, and a copolymer of the acrylic acid Guerbet alcohol ester, phenethylene, maleic anhydride, vinyl acetate and the like can be extensively applied to the field of preparation of coatings, adhesives, refined oil product flowability modifiers, raw oil pour point depressants, biomedical compatible materials and the like.

Description

technical field [0001] The invention belongs to the field of alcohol acrylate and its preparation, in particular to a Guerbet alcohol acrylate, its preparation method and its application. Background technique [0002] Higher alcohol acrylate polymers with long side chains are a kind of side chain crystalline polymers with "temperature switch" characteristics, and are temperature-sensitive polymer smart materials that have attracted some research interest in recent years. This kind of side chain crystalline polymer has two morphological structures, crystalline state and amorphous state, and the different morphological structures depend on the ambient temperature. When the temperature is lower than the melting point of the side chain, the polymer is a crystalline structure, which belongs to a typical "comb" structure; when the temperature is higher than the melting point of the side chain, the polymer is an amorphous structure; this change is a physical change, It is reversi...
