Advanced Fatty Acid Methyl Ester Sulfonation Process

Fatty Acid Methyl Ester Sulfonate (MES) is a green anionic surfactant derived from natural oils and fats, featuring excellent calcium soap dispersibility, low irritation, and good biodegradability. Nanjing Qino Automatic Control Equipment Co., Ltd. possesses mature technology in the design and manufacturing of MES production plants, employing advanced sulfonation processes and optimized post-treatment technology to ensure stable product quality.

Our MES production plant utilizes SO₃ Film Sulfonation Technology, combined with proprietary bleaching, neutralization, and blending processes, to produce high-quality MES products with high Active Matter Content, light Color, and excellent calcium soap dispersibility.

Core Process Flow

Sulfonation Reaction System

• Utilizes a new multi-tube falling film sulfonation reactor.
• Sulfonation reaction between fatty acid methyl ester and SO₃.
• Strict temperature control to prevent oxidation and side reactions.
• Secondary protective air technology to improve product quality.
• Key Control: Precise control of SO₃/fatty acid methyl ester molar ratio.

Aging System

• Sulfonation product enters aging tank for maturation.
• Controlled aging temperature and time.
• Promotes complete reaction, increasing Active Matter Content.
• Aged product exhibits good stability.

Bleaching System (Critical Process)

• Key step for MES product Color control.
• Employs oxidative or reductive bleaching process.
• Controlled bleaching temperature and time.
• Ensures light product Color, meeting standards.

Neutralization System

• Continuous neutralization process.
• NaOH solution neutralizes sulfonic acid.
• Controlled neutralization pH Value.
• Can produce liquid MES or spray-dried powder.

Post-Treatment System

• Degassing treatment.
• Filtration to remove impurities.
• Adjustment of Active Matter Content.
• Spray drying to powder (powdered MES).

Applications & Markets

The Ideal Choice For Green Detergents

MES (Fatty Acid Methyl Ester Sulfonate) is a green anionic surfactant derived from natural oils and fats (palm oil, coconut oil, etc.), featuring excellent calcium soap dispersibility, low irritation, good biodegradability, and environmental friendliness. It is widely used in detergents, personal care, and other fields, serving as an eco-friendly alternative to traditional surfactants.

Main Application Areas

• Phosphate-Free Laundry Powder: Primary active ingredient, excellent calcium soap dispersibility.
• Concentrated Laundry Powder: High Active Matter Content, strong detergency.
• Liquid Detergents: Good compatibility, excellent low-temperature solubility.
• Dishwashing Detergents: Efficient stain removal, easy rinsing.

Detergent Industry

• Bar Soap: Gentle cleansing, low irritation.
• Body Wash: Good skin affinity.
• Facial Cleanser: Gentle, non-tightening.
