Sodium Lauroyl Methyl Isethionate (SLMI) is a mild anionic, surfactant with a long-lasting, fine foam, excellent cleaning properties, and a rapid foaming speed. Solid content: 77%-85%

Description of Sodium Lauroyl Isethionate ：

Chemical structure: Sodium lauryl methyl methanesulfonate is composed of lauric acid, a methyl group and sodium isopropyl sulfonate and other parts, with two groups of lipophilic and hydrophilic, so it has good solubility and surface activity.

Surface activity: Sodium lauryl methyl isoethanesulfonic acid has a lower critical micelle concentration (CMC), which can effectively reduce surface tension at lower concentrations and promote wetting, emulsification, dispersion and stability.

Solubility: Sodium lauryl methyl isoethanesulfonate has good solubility and can be dissolved in water, alcohol, ketone and other solvents, forming a transparent solution. In addition, it is stable over a wide pH range and has good resistance to hard water.

Stability: Sodium lauryl methyl isoethanesulfonic acid has good chemical stability, is not easy to decompose and deteriorate, and can withstand a certain range of acid-base and salt environments. In addition, it also has good heat resistance, which can maintain its stability at high temperatures.

Biocompatibility: Sodium lauryl methyl isoethanesulfonic acid is less irritating to the skin, has low toxicity or non-toxic, has good biodegradability, and is friendly to the environment. However, due to its irritability, appropriate protective measures should be taken during use.

Production Method of Sodium Lauroyl Methyl Isethionate: 

Esterification reaction: Synthesizing sodium lauryl methyl methanesulfonate first requires esterifying lauric acid with methyl isopropyl sulfonyl chloride. In esterification, lauric acid reacts with methyl isopropyl sulfonyl chloride under appropriate temperature and pressure conditions, usually using an acid or base as a catalyst to promote the esterification reaction. During the reaction process, parameters such as reaction temperature, pressure and raw material ratio need to be controlled to ensure the smooth progress of the reaction and the generation of the target product.

Sulfonation reaction: After the completion of the esterification reaction, the generated methyl isopropyl sulfonate needs to be sulfonated, and sulfonic acid groups are introduced. The sulfonation reaction is usually carried out under higher temperature and pressure conditions, using sulfonating agents such as sulfuric acid or chlorosulfonic acid. In the process of sulfonation reaction, it is necessary to control the reaction temperature strictly.

Salinization: After the sulfonation reaction, the resulting sulfonate must undergo a salinization reaction to convert it into sodium or calcium salt. The salinization reaction usually uses a base such as sodium hydroxide or calcium hydroxide as a neutralizer to neutralize the sulfonic acid group in the sulfonate into a salt. In the process of salinization reaction, it is necessary to control the amount of neutralizer and reaction temperature to ensure the purity and yield of the target product.

Separation and purification: After the above reaction steps, the product obtained is a mixture, which needs to be separated and purified. It is usually separated and purified by crystallization, filtration and recrystallization to obtain high-purity sodium lauryl methyl isoethanesulfonate. The purpose of separation and purification is to remove by-products and impurities and improve the purity and yield of the target product.

Wastewater treatment: A certain amount of wastewater is generated during production and needs to be treated appropriately. The wastewater may contain unreacted raw materials, by-products and catalysts. Wastewater treatment can reduce environmental pollution and waste of resources.

Waste gas treatment: A certain amount of waste gas may also be generated during production, which needs to be properly treated. Waste gas may contain volatile organic compounds, sulfur oxides and other harmful substances. According to the characteristics and emissions of waste gas, different methods can be used for waste gas treatment, such as absorption, adsorption, catalytic combustion, etc. Waste gas treatment can reduce the pollution of the atmospheric environment.

Waste residue treatment: The waste residue generated during production must be properly treated. The waste residue may contain harmful substances such as solid and chemical waste. According to the characteristics and the amount of waste residue, waste residue treatment can adopt different methods, such as incineration, landfill, recycling, etc. Waste residue treatment can reduce the pollution of the soil and groundwater environment.
