Embodiment 1

[0059] Step 1. Put 282.47kg (1000mol) of oleic acid into the polymerization vessel, add 3kg of potassium hydroxide and stir, and then pass nitrogen into the polymerization vessel to change the air in the vessel. When the nitrogen in the polymerization vessel maintains a positive pressure, use nitrogen to enter the vessel. The material tank pushes 440.52 (10000mol) ethylene oxide into the polymerization vessel, while stirring and heating to 100°C, adjusting the pressure to 0.3MPa, after 3.5 hours of polymerization, extrude the polymer in the polymerization vessel with nitrogen, which is oleic acid Polyoxyethylene (10) ether.

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

Embodiment 2

[0063] Step 1. Put 144.20kg (1000mol) of isooctanoic acid into the polymerization kettle, add 2.4kg of sodium hydroxide and stir, and then pass nitrogen into the polymerization kettle to change the air in the kettle. When the nitrogen in the polymerization kettle maintains a positive pressure, use nitrogen The feed tank pushes 660.78 (15000 mol) of ethylene oxide into the polymerization tank, while stirring, the temperature is raised to 90°C, the pressure is adjusted to 0.35 MPa, and after 5 hours of polymerization, the polymer in the polymerization tank is extruded with nitrogen, which is Polyoxyethylene caprylate (15) ether.

[0064] Step 2: Add the isooctanoic acid polyoxyethylene (15) ether and 49.03kg (500mol) maleic anhydride produced in the reaction of Step 1 into the reactor, add an aqueous solution containing 3.5kg of concentrated sulfuric acid, and fill with nitrogen to switch out the air in the reactor The reaction temperature is: 180℃; the reaction time is: 5 hours; a...

Embodiment 3

[0067] Step 1. Put 284.48kg (1000mol) of stearic acid into the polymerization kettle, add 1.2kg of potassium hydroxide and stir, and then pass nitrogen into the polymerization kettle to change the air in the kettle. When the nitrogen in the polymerization kettle maintains a positive pressure, use The nitrogen feed tank pushes 88.1kg (2000mol) of ethylene oxide into the polymerization vessel while stirring and heating to 110°C, and the pressure is adjusted to 0.25MPa. After 2 hours of polymerization, the polymer in the polymerization vessel is extruded with nitrogen, namely It is stearic acid polyoxyethylene (2) ether.

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

Abstract

The invention provides a fatty acid polyoxyethylene succinate sulfonate, which is characterized in that it has the following structure: wherein, n is an integer of 2 to 15, R is a hydrocarbon group with 7 to 19 carbon atoms, and M is Na or K, the micro-cutting fluid produced by using the fatty acid polyoxyethylene succinate sulfonate provided by the invention has good lubricity and biodegradability compared with the prior art, and a very small amount of micro-cutting fluid It can meet the high-end requirements of metal processing, reduce the harm to the environment and workers, and minimize the pollution to the environment.

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] Traditional metal processing lubrication and cooling use cutting oils, coolants, emulsions and other lubricants 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. It is harmful to the environment and not only wastes resources, but also causes huge pollution of processing places and the environment. [0003] The processed workpieces must be cleaned with a large amount of cleaning solvents before the next process is processed, causing a large amount of pollutant emissions. At the same time, the cleaning agents often contain chlorides (such as dichloromethane, tetrachloroethylene), phosphides (such as Tripol...
