Description

Technical Field

[0001] The present invention relates to the technical field of sodium alkyl sulfonate preparation, and specifically to a high-activity sodium alkyl sulfonate low-temperature stable formulation and preparation process. Background Art

[0002] Sodium alkyl sulfonate can reduce the surface tension of liquids, making it perform excellently in cleaning and washing processes. It is applicable to various products such as cleaners, detergents, and shampoos. Sodium alkyl sulfonate exhibits good foam stability performance in cosmetics and detergents, capable of providing rich foam and maintaining its stability. It can mix water and oil, and is applicable as an emulsifier to help separate and disperse oil stains and other dirt. Sodium alkyl sulfonate has good biodegradability and is an environmentally friendly green surfactant, meeting the development trend of environmental protection. Even under hard water conditions, sodium alkyl sulfonate can maintain its washing effect and also has good foaming ability.

[0003] Comparative document, application number CN202111003891.2. The present invention discloses a production method of sodium alkyl sulfonate, which includes the following steps: (1) Mix vinyl sulfonic acid and hydrogen to form a mixed raw material, heat the mixed raw material to a first set temperature and then enter a hydrogenation reactor for hydrogenation reaction to generate a reaction mixture; (2) Perform gas-liquid separation on the reaction mixture, remove the hydrogen in the reaction mixture to form a crude product of alkyl sulfonic acid, and the removed hydrogen is returned to the mixed raw material for recycling; (3) React the crude product of alkyl sulfonic acid with sodium hydroxide to generate a crude product of sodium alkyl sulfonate; (4) Separate the crude product of sodium alkyl sulfonate to obtain sodium alkyl sulfonate. In this application, while performing the hydrogenation reaction of vinyl sulfonic acid, the sultone also undergoes a ring-opening reaction and is ultimately converted into sodium alkyl sulfonate. Since the conversion rate of the raw materials can reach over 96%, the product does not need to be refined again, and the raw materials do not need to be recycled, shortening the production process route and reducing the product cost;
