Embodiment Construction

[0016] The invention provides a novel surfactant of sodium cardanol, which has the following structural formula:

[0017]

[0018] Among them, R stands for C 15 h 31 .

[0019] The present invention also provides the preparation method of the above-mentioned sodium salt cardanol novel surfactant, utilizes cardanol and sulfonating reagent to react, then prepares the cardanol novel surfactant after being neutralized with alkali containing sodium ions, and the equation of its reaction as follows:

[0020]

[0021] Further, during the reaction, cardanol is first added to the reactor, and then the sulfonating reagent is added to react, wherein the molar ratio of cardanol to the sulfonating reagent is 1:0.8-1.2, and the product is adjusted with alkali containing sodium ions after discharging The pH value is alkaline, and the novel cardanol surfactant is obtained by filtration.

[0022] Further, in the added material, the purity of the cardanol is greater than or equal to 8...

Abstract

The invention provides a novel sodium salt cardanol surfactant, which has the following structural formula, wherein R represents C15H31. The invention also provides a preparation method for the novel sodium salt cardanol surfactant. High-purity cardanol extracted from natural cashew nut shells is innocuous and light in color; and the innocuous environment-friendly novel cardanol surfactant with excellent performance can be obtained by sulfonation reaction of the regenerative biomass cardanol and alkali neutralization. Meanwhile, the novel sodium salt cardanol surfactant has the advantages of good hydraulic lubricating property, strong detergency, moderate foam, good dissolution, low skin irritation, good biodegradability and good compatibility with other surfactants.

Description

Technical field: [0001] The invention relates to the field of chemistry, in particular to an organic compound and a preparation method thereof, in particular to a novel sodium salt cardanol surfactant and a preparation method thereof. Background technique: [0002] The application of surfactants is very extensive, and has penetrated into various civil and industrial fields. Surfactants are amphiphilic compounds, and at least one group in their molecules has an affinity for polar surfaces, which can ensure their dissolution in water. sex, another group has no affinity for water, but has lipophilic properties. The hydrophilic groups of ordinary surfactants are polar groups such as carboxylic acid groups, sulfonic acid groups, sulfate groups, phosphates, amine salts, quaternary ammonium salts, oxyethylene, etc., and the lipophilic groups are non-polar hydrocarbon chains. . The main sources of raw materials for lipophilic groups are two categories, one is mineral (fossil) reso...
