Mixture containing fatty acid ethyl ester sulfonate and preparation method thereof

Abstract

The invention relates to a mixture with aliphatic acid carbethoxy sulfonate salt, and relative production, wherein said mixture comprises 90-98 deals of aliphatic acid sulfonate salt, 1-4 deals of aliphatic acid sulfonate salt, 0.5-4 deals of sulfate, 0.1-2 deals of fatty acid ester, 0.3-3 deals of ethylsulfuric acid salt, and 1-50 deals of water. The production comprises that: 1, sulfonating the fatty acid ester and sulfur trioxide at 1:1-1:1. 1 mol ratios; 2, adding alcohol into mixture to be aged; 3, adding auricome into mixture to poach; 4, adding extractive into the mixture to extract; 5, adding alkali metal mixture into mixture to be neutralized to obtain the mixture. The inventive production is safe while the product purity is higher than 90%.

Description

technical field [0001] The invention belongs to the field of organic chemistry, and in particular relates to a mixture containing fatty acid ethyl ester sulfonate and a preparation method thereof. Background technique [0002] Fatty acid ester sulfonates are widely used as surfactants in the fields of medicine, daily chemicals, and washing. For detergents such as washing powder, sodium alkylbenzene sulfonate is often used as a surfactant. The disadvantage is that sodium alkylbenzene sulfonate contains benzene rings and is a carcinogen; It has good detergency under certain conditions, so when washing clothes, it will cause damage to protein fibers, and if it is washed by hand, it will also have an adverse effect on the skin; third, in order to increase the washing effect, it is often necessary to add sodium tripolyphosphate as a water softener , and the discharge of phosphorus-containing substances pollutes the environment. As an alternative product, people use fatty acid m...
