Problems solved by technology

[0002] Modern pesticides are changing rapidly and are developing in the direction of environmental protection. Water-based and solidification are the main directions. However, at present, domestic pesticide adjuvants are not very developed. Currently, several types of pesticides containing multiple benzene ring structures are commonly used. It has excellent emulsifying and dispersing properties, but its application in water-based formulations is still lacking, and there are more or less problems in physical stability, especially when it is stable over time. There are often serious stratification phenomena in terms of performance, and there is still a big gap in overall performance compared with developed countries
[0003] There are many varieties of succinate esters, such as alkylphenols, fatty alcohols, etc., but the modification of polyphenylene ring polyethers has not been reported.

Embodiment 1

[0025] Example 1: Add polyphenylene ring polyether (triphenylethylphenol polyether, molecular weight 2000-2500) and maleic anhydride into the reactor at a molar ratio of 1:1, start stirring, and the esterification temperature is 80-100°C. °C without catalyst, react under nitrogen protection conditions for 4 hours to obtain polyphenyl ring polyether succinate, then add sulfonating agent (sulfuric acid) and react at 100-170 °C for 3-4 hours to obtain the finished product: polyphenyl ring Polyether succinate sulfonate.

Embodiment 2

[0026] Example 2: Add polyphenylene ring polyether (triphenylethylphenol polyether, molecular weight 2000-2500) and maleic anhydride into the reactor at a molar ratio of 1:1, start stirring, and the esterification temperature is 80-100°C , without a catalyst, reacted for 4 hours under the condition of nitrogen protection, and then added an equiproportional mole of polyphenylene ring polyether to the reactor. Until very few, add sulfonating agent (fuming sulfuric acid) into the reaction kettle, react at 100-170°C for 3-4 hours, and obtain the finished product: polyphenylene ring polyether succinate sulfonate.

Embodiment 3

[0027] Example 3: Add polyphenylene ring polyether (triphenylethylphenol polyether, molecular weight 1500-2000) and maleic anhydride in a molar ratio of 1:1 into the reactor, start stirring, and the esterification temperature is 80-100°C. Without catalyst, react under nitrogen protection for 4 hours to obtain polyphenylene ring polyether succinate, then add sulfonating agent (sulfamic acid) and react at 100-170 °C for 3-4 hours to obtain the finished product: benzene ring polyether succinate Ether succinate sulfonate.

Abstract

The invention discloses a preparation method of multi-benzene-ring polyether succinate, which comprises the following step: esterifying multi-benzene-ring polyether and maleic anhydride at 80-100 DEG C for 4-8 hours to obtain the multi-benzene-ring polyether succinate, wherein the mol ratio of the multi-benzene-ring polyether to the maleic anhydride is (1.0-2.5):1. The invention also discloses a preparation method and application of multi-benzene-ring polyether succinate sulfonate. The preparation method of multi-benzene-ring polyether succinate sulfonate comprises the following steps: adding a sulfonating agent into the multi-benzene-ring polyether succinate, sulfonating at 100-170 DEG C for 4-6 hours, and neutralizing with alkali to obtain the multi-benzene-ring polyether succinate sulfonate. The multi-benzene-ring polyether succinate sulfonate can be used in pesticide water-based preparations, synthetic resins, paint, papermaking, binding agents, fibers or construction materials.
