FMES-2 Fatty Acid Methyl Esters Ethoxylate Sulfonate CAS 71338-19-24

FMES is a sulfate anionic new surfactant. It is easily soluble, dispersible, compatible with hard water, and has high electrolyte stabilization.Active matter content: 70%

Description of Fatty Acid methyl Esters Ethoxylate Sulfonate：

Chemical structure: Fatty acid methyl ester ethoxysulfonate is an anionic surfactant produced by a chemical reaction between a fatty acid methyl ester and an ethoxysulfonate. Its molecular structure contains a hydrophilic sulfonic acid group and a hydrophobic fatty acid methyl ester group.

Solubility: FMEE has a low solubility in water, but the solubility increases in alkaline water solutions. Its solubility is also affected by temperature, salinity and other solvents.

Biodegradability: FMEE has a relatively high biodegradability and can be decomposed into methanol, ethoxysulfonate and fatty acids by microorganisms. However, water quality, temperature, and other environmental factors may affect its biodegradation process.

Irritants: FMEE is somewhat irritating to the skin and eyes but less irritating than other surfactants.

Stability: FMEE is unstable under high temperatures and strong acid conditions, and decomposition reactions will occur. Under alkaline conditions, its stability is better.

Uses: FMEE is widely used in personal care products, industrial cleaning agents, pesticide emulsifiers and other fields. Due to its low toxicity and biodegradability, it is also used to prepare environmentally friendly detergents and cleaners.

Compatibility: FMEE works well with a variety of compounds but, in some cases may precipitate or degrade performance when mixed with other surfactants or electrolytes.

Safety: However, long-term exposure or heavy use may have adverse health effects. Therefore, the guidelines and safety precautions on the product label should be followed.

Coatings and paints: In coatings and paints, FMEE can improve the rheology and stability of the paint and improve the adhesion and uniformity of the paint.

Production Method of Fatty acid methyl esters ethoxylate sulfonate：

Raw material preparation

Ethoxysulfonate: Ethoxysulfonate is another important raw material of FMEE, which can be prepared by reacting sodium sulfate or sodium bisulfate with ethylene oxide by ethoxylation.

The reaction process

Mixing: The fatty acid methyl ester and ethoxy sulfonate are mixed proportionally, usually by mechanical stirring or air mixing.

Esterification reaction: Under certain temperatures and pressures, fatty acid methyl ester and ethoxy sulfonate are esterified by a catalyst. The catalyst is usually acidic, such as sulfuric acid, phosphoric acid, etc.

Sulfonation reaction: After the completion of the esterification reaction, the reaction product is sulfonated further to react the ethoxy sulfonate with the fatty acid methyl ester. The sulfonation reaction is usually carried out under high temperatures and pressures.

Washing and drying: The reaction products are washed to remove excess catalysts and by-products and then dried to obtain FMEE products.

Process control

Temperature: The temperature of esterification and sulfonation reactions has an important effect on product quality and production efficiency. Generally, the esterification reaction temperature is controlled at 100-200℃, and the sulfonation reaction temperature is controlled at 150-250℃.

Pressure: Esterification and sulfonation reactions are usually carried out under certain pressure to promote the reaction's progress and improve the product's purity.

Catalyst: The choice of catalyst has an important effect on the rate of esterification and sulfonation reaction and the purity of the product. Common catalysts are sulfuric acid, phosphoric acid and so on.

Material ratio: The fatty acid methyl ester and ethoxy sulfonate ratio affect product quality and production cost. According to the actual demand, the optimal ratio can be determined by experiment.

Washing and drying conditions: Washing and drying conditions impact the purity and quality of the product. Appropriate detergents and drying methods should be selected to ensure product purity and moisture content meet the requirements.

Quality testing

Appearance inspection: Check the appearance of FMEE products, such as color, transparency, etc.

Purity test: Gas chromatography, liquid chromatography, and other methods to detect the purity of FMEE products.

Moisture content detection: The drying weight loss method detects the moisture content of FMEE products.

Stability test: The stability of FMEE products is tested by accelerated aging tests and other methods.

Biodegradability test: Test the biodegradability of FMEE products according to relevant standards.
