MES Sodium Fatty Acid Methyl Esters Sulfonate CAS 93348-22-2

MES is a brand new type of sulfate anionic surfactant. It is easily soluble, dispersible, compatible with hard water, and has high electrolyte stabilty.Active matter content 70-90%

Description of Sodium Methyl Esters, or MES as it is also known:

Physical property

Appearance: Fatty acid methyl ester sodium sulfonate is usually a white or light yellow powder or granular solid, odorless or slightly characteristic odor.

Solubility: easily soluble in water, forming a transparent or translucent solution. It is more soluble in hot water and less soluble in cold water.

Stability: stable at room temperature, not easy to decompose. However, it may decompose under high temperatures and strong acid or alkali conditions.

Melting point: The melting point of fatty acid methyl ester sodium sulfonate varies with its molecular structure and carbon chain length, generally between 50-100 ° C.

Chemical properties

Anionic surfactant:  Its molecular structure contains hydrophilic groups (sulfonate) and hydrophobic groups (long carbon chains) so that it can have both water and oil affinity, thereby reducing the surface tension of water and improving decontamination ability.

Acid-base stability: fatty acid methyl ester sodium sulfonate can maintain good stability under weak acid or weak base conditions. However, under strong acid or base conditions, decomposition reactions may occur to produce corresponding acids and alcohols.

Compatibility with other surfactants: Fatty acid methyl ester sodium sulfonate can be combined with other anionic, non-ionic and cationic surfactants to produce synergies and improve decontamination ability.

Biodegradability: Fatty acid methyl ester sodium sulfonate has good biodegradability and will not cause persistent environmental pollution.

Technical Parameter of PHES Sodium 2Propyl-1Heptanol Ethersulfate

Applications of MES Sodium Fatty Acid Methyl Esters Sulfonate:

Washing products: Fatty acid methyl ester sodium sulfonate is one of the main components of washing products, widely used in washing powder, washing liquid, detergent and other products. It can reduce the surface tension of water, penetrate between the fibers of the clothing, wrap the oil and carry it away from the surface of the clothing, and produce a synergistic effect with other surfactants to improve the washing effect.

Cosmetics: Fatty acid methyl ester sodium sulfonate is also widely used in cosmetics, such as shampoo, body wash, hand sanitizer and so on. It can play the role of emulsification, solubilization, wetting, etc., improving product use and comfort.

Food processing: Fatty acid methyl ester sodium sulfonate also has applications in food processing, such as an emulsifier in food additives. It can improve the taste and stability of food and improve its quality and shelf life.

Petrochemical: Fatty acid methyl ester sodium sulfonate also has applications in the petrochemical industry, such as emulsifiers and demulsifiers for oil field production fluids. It can improve the flow of produced liquid and the efficiency of oil production.

Leather treatment: Fatty acid methyl ester sodium sulfonate has applications in leather treatment, such as a leather softener and water repellent. It can improve the softness and water resistance of leather and improve its quality and durability.

Other fields: Besides the above application fields, sodium fatty acid methyl ester sulfonate can be used in coating, textile, printing and dyeing, pesticides and other fields. It can play a role in wetting, emulsifying, dispersing, etc., and improve the performance and use effect of the product.

Production Method of MES Sodium Fatty Acid Methyl Esters Sulfonate:

Raw material preparation

Fatty acid methyl ester sodium sulfonate includes fatty acid methyl ester and sulfur trioxide. Fatty acid methyl ester can be obtained by a transesterification reaction between oil and methanol under the action of a catalyst or can also be prepared by other methods, such as esterification. The interaction of sulfuric acid and nitric oxidizer can obtain sulfur trioxide.

The reaction process

Fatty acid methyl ester reacts with sulfur trioxide.

The fatty acid methyl ester was mixed with sulfur trioxide in a particular proportion, and the reaction was carried out at a specific temperature and pressure. During the reaction, sulfur trioxide and the hydroxyl group of fatty acid methyl ester are sulfonated to form the corresponding sulfonate. This reaction is exothermic, so the temperature needs to be controlled to prevent the reaction from overheating.

Post-treatment of sulfonation reaction

After the reaction, the mixture must be separated to obtain the fatty acid methyl ester sodium sulfonate. In the separation process, distillation, crystallization, recrystallization, and other methods can be chosen according to the specific process conditions.

Product purification

The obtained fatty acid methyl ester sodium sulfonate may contain some impurities and must be purified. Standard purification methods include recrystallization, ion exchange, etc. These methods remove the impurities in the product, and high-purity fatty acid methyl ester sodium sulfonate can be obtained.

Packaging and storage

Finally, the high-purity fatty acid methyl ester sodium sulfonate was packaged and stored. Packaging materials with good sealing, moisture-proof and shock-proof are generally used to prevent products from being affected by the external environment. When storing, paying attention to temperature and humidity control is necessary to prevent moisture or product deterioration.
