Embodiment 1

[0039] In a 500ml four-neck flask equipped with a stirring, thermometer and fractionating tower, add 80g of octylphenol polyoxyethylene ether (OP-10), 80g of methyl methacrylate, 70g of n-hexane, and 0.3g of polymerization inhibitor Z-701 , heating, start stirring, keep the temperature of the kettle at about 105°C, make the mixed reaction liquid azeotrope, separate water, until the distillate is clear and the temperature at the top of the tower reaches 68.5°C.

[0040] Then add 2.0 g of tetraethyl titanate into the reaction kettle, keep warm for reaction, take samples to analyze the methanol content in the azeotrope at the top of the tower, and stop the reaction when the methanol content in the azeotrope at the top of the tower is lower than 0.1%.

[0041] A total of 55.0 g of azeotrope was obtained in the reaction, the methanol content was 6.7% according to sampling analysis, and the conversion rate of octylphenol polyoxyethylene ether was 93.05%.

[0042] Add 20g of 10% sulf...

Abstract

The present invention relates to the preparation and use of alkylphenol ethoxylate (methyl) acrylic ester. The preparation is preferably a ester exchange reaction process including azeotropic dewatering of the mixture of alkylphenol ethoxylate and acrylic ester or methyl acrylic ester in the presence of azeotropic solvent and polymerization inhibitor, ester exchange reaction in the presence of catalyst, separating and recovering azeotropic solvent and acrylic ester or methyl acrylic ester to obtain alkylphenol ethoxylate (methyl) acrylic ester. The technological process is simple and has no polymerization of the material in the reactor and separating tower, good product appearance and alkylphenol ethoxylate converting rate up to 80-95 %.

Description

technical field [0001] The invention relates to an ester product and its preparation process and application, in particular to alkylphenol polyoxyethylene ether (meth)acrylate and its preparation and application. Background technique [0002] As we all know, alkylphenol polyoxyethylene ether is a kind of surfactant, which not only has lipophilic group (alkylphenol group) and hydrophilic group (polyoxyethylene group), but also has molecular polarity along with molecular The number of oxyethylene groups can be increased or decreased, and the HLB value can be adjusted according to needs. It is the most widely used nonionic surfactant in the world. However, the molecular weight of alkylphenol polyoxyethylene ether is small, and its water solubility is good, which also determines that its use is limited to a certain extent. If it is used on the surface of fibers and other substances, the surface bonding force is poor, and the performance will be lost due to washing, friction and...
