Embodiment 1

[0059] Step 1. Put 282.47kg (1000mol) of oleic acid into the polymerization kettle, add 3kg of potassium hydroxide and stir, then feed nitrogen into the polymerization kettle to convert the air in the kettle, and when the nitrogen in the polymerization kettle maintains positive pressure, use nitrogen to Push 440.52 (10000mol) ethylene oxide into the polymerization tank in the material tank, and at the same time stir the temperature to 100°C and adjust the pressure to 0.3MPa. After 3.5 hours of polymerization, use nitrogen to squeeze out the polymer in the polymerization tank, which is oleic acid Polyoxyethylene(10) ether.

[0060] Step 2: Add oleic acid polyoxyethylene (10) ether and 58.04kg (500mol) maleic acid produced in step 1 into the reaction kettle, add 11kg of cation exchange resin, and fill with nitrogen to convert the air in the reaction kettle for reaction , The reaction temperature is: 200°C; the reaction time is: 4 hours; after the reaction, the water is decompres...

Embodiment 2

[0063] Step 1. Put 144.20kg (1000mol) of isooctanoic acid into the polymerization kettle, add 2.4kg of sodium hydroxide to stir, then feed nitrogen into the polymerization kettle to convert the air in the kettle, and when the nitrogen in the polymerization kettle maintains positive pressure, use nitrogen The feeding tank pushes 660.78 (15000mol) ethylene oxide into the polymerization kettle, while stirring and raising the temperature to 90°C, and adjusting the pressure to 0.35MPa. After 5 hours of polymerization, the polymer in the polymerization kettle is extruded with nitrogen gas, which is iso Octanoic acid polyoxyethylene (15) ether.

[0064] Step 2: Add the isooctanoic acid polyoxyethylene (15) ether and 49.03kg (500mol) maleic anhydride produced in step 1 into the reactor, add an aqueous solution containing 3.5kg of concentrated sulfuric acid, and fill with nitrogen to convert the air in the reactor Carry out the reaction, the reaction temperature is: 180°C; the reaction...

Embodiment 3

[0067] Step 1, 284.48kg (1000mol) stearic acid is dropped in the polymerization still, add the potassium hydroxide of 1.2kg and stir, then pass into the air in the nitrogen conversion still in the polymerization kettle, when the nitrogen in the polymerization kettle keeps positive pressure, use The nitrogen feed tank pushes 88.1kg (2000mol) of ethylene oxide into the polymerization kettle, while stirring and raising the temperature to 110°C, and adjusting the pressure to 0.25MPa. After 2 hours of polymerization, the polymer in the polymerization kettle is extruded with nitrogen, that is It is polyoxyethylene stearate (2) ether.

[0068] Step 2: Add the stearic acid polyoxyethylene (2) ether and 58.04kg (500mol) fumaric acid produced in step 1 into the reactor, add 8.6kg of cation exchange resin, and fill with nitrogen to convert the air in the reactor Carry out the reaction, the reaction temperature is 220°C; the reaction time is 3 hours; after the reaction, the water is decom...

Abstract

The invention provides a fatty acid polyoxyethylene succinic acid ester sulfonate, which is characterized by having a structure shown in the specification. Specifically, n is an integer of 2-15, R is alkyl with a carbon atom number of 7-19, and M is Na or K. Compared with the prior art, the micro-cutting fluid made from the fatty acid polyoxyethylene succinic acid ester sulfonate provided by the invention has good lubricity and biodegradability, a small amount of the micro-cutting fluid can meet the high-end demands of metal processing, the harm to the environment and workers is reduced, and the environmental pollution can be minimized.

Description

technical field [0001] The invention relates to the technical field of synthetic chemistry, in particular to fatty acid polyoxyethylene 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), phos...
