Embodiment 1

[0055] Step 1. Put 282.47kg (1000mol) of oleic acid and 61.08kg (1000mol) of monoethanolamine into the reactor respectively, while stirring and raising the temperature to 90°C. After 1 hour of reaction, oleic acid monoethanolamide is obtained.

[0056] Step 2: Add the oleic acid monoethanolamide and 58.04kg (500mol) maleic acid generated in step 1 into the reactor, add 8kg of cation exchange resin, fill in nitrogen to convert the air in the reactor to react, and the reaction temperature is : 200°C; Reaction time: 4 hours; After the reaction, the water is decompressed and the cation exchange resin is removed, which is oleic acid monoethanolamide maleate.

[0057] Step 3: Fully stir the oleic acid monoethanolamide maleate and the aqueous solution containing 120.17 kg (1000 mol) of potassium bisulfite produced in the reaction of step 2, and react to remove water to generate oleic acid monoethanolamide succinate sulfonate Potassium acid.

Embodiment 2

[0059] Step 1. Put 144.20 kg (1000 mol) of isooctanoic acid and 61.08 kg (1000 mol) of monoethanolamine into the reaction kettle, stir at the same time and raise the temperature to 70 ° C. After 2 hours of reaction, it is isooctanoic acid monoethanolamide.

[0060] Step 2: Add the isooctanoic acid monoethanolamide ether and 49.03kg (500mol) maleic anhydride generated in step 1 into the reaction kettle, and add H 2 SO 4 Sulfuric acid 1.25kg aqueous solution, filled with nitrogen to convert the air in the reactor to react, the reaction temperature is: 180 ° C; the reaction time is: 5 hours; after the reaction, part of the water is decompressed and neutralized by adding potassium hydroxide to a pH of 8 ~8.5, that is, isooctanoic acid monoethanolamide maleate.

[0061] Step 3: Fully stir the isooctanoic acid monoethanolamide maleate and the aqueous solution containing 104.06 kg (1000 mol) of sodium bisulfite formed in the reaction of step 2 to react and remove the water to genera...

Embodiment 3

[0063] Step 1. Put 284.48kg (1000mol) of stearic acid and 61.08kg (1000mol) of monoethanolamine into the reaction kettle respectively, stir at the same time and raise the temperature to 80°C, and react for 1.5 hours to obtain stearic acid monoethanolamide.

[0064] Step 2: Add the stearic acid monoethanolamide and 58.04kg (500mol) fumaric acid produced in step 1 into the reactor, add 4.036kg of cation exchange resin, fill in nitrogen to convert the air in the reactor for reaction, and react The temperature is: 220°C; the reaction time is: 3 hours; after the reaction, the water is decompressed and the cation exchange resin is removed to obtain stearic acid monoethanolamide fumarate.

[0065] Step 3: Fully stir the stearic acid monoethanolamide fumarate and the aqueous solution containing 120.17 kg (1000 mol) of potassium bisulfite produced by the reaction in step 2 to carry out the reaction, remove the water by reverse osmosis, and generate stearic acid monoethanolamide fumarate...

Abstract

The invention provides a preparation method for fatty acid monoethanolamide succinate sulfonate. The preparation method is characterized by comprising the steps of generating amidation reaction by fatty acid and monoethanolamide to generate fatty acid monoethanolamide which is reacted with butenedioic acid or maleic anhydride to generate fatty acid monoethanolamide butenedioic acid ester, and generating salt formation reaction of the fatty acid monoethanolamide butenedioic acid ester and hydrosulphite to generate the fatty acid monoethanolamide succinate sulfonate. Compared with the prior art, trace cutting liquid prepared from the fatty acid monoethanolamide succinate sulfonate provided by the invention has high lubricating property, extreme pressure antiwear property and biological degradability; a high-end requirement on metal processing can be met only by using an extremely small amount of the trace cutting liquid; therefore, harm to the environment and workers is alleviated, and the pollution to the environment is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of synthetic chemistry, in particular to fatty acid monoethanolamide succinate sulfonate and its preparation method and application. Background technique [0002] Cutting oils, coolants, emulsions and other lubricants used in traditional metal processing lubrication and cooling are used in large quantities, and traditional cutting oils use mineral oil as the base oil, which is not easy to decompose in the natural environment, and most of the additives used are harmful to the human body. Harmful to the environment, it not only wastes resources, but also causes huge pollution of processing sites and the environment. [0003] The finished workpiece needs to be cleaned with a large amount of cleaning solvent before processing in the next process, resulting in a large amount of pollutant discharge. At the same time, the cleaning agent often contains chlorides (such as methylene chloride, tetrachloroethylene), pho...
