Fatty acid polyoxyethylene sulfosuccinate sulfonate and its preparation and use

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.
