Production Method of GMS Glyceryl monostearate :

Chemical synthesis

Chemical synthesis is the main method of producing glycerol monostearate, prepared by esterification of glycerol and stearic acid. The following are the specific steps of chemical synthesis:

Raw materials: Glycerin and stearic acid are the main raw materials. Glycerin can be extracted from natural oils or produced by the petrochemical industry. Stearic acid is obtained by hydrogenation of oil under certain conditions and is a white to slightly yellow waxy solid at room temperature.

Esterification reaction: glycerol and stearic acid are mixed according to a certain proportion, and catalysts such as sulfuric acid, phosphoric acid or sodium hydroxide are added to esterify the reaction at a certain temperature. 

Separation and purification: After esterification, the product will contain impurities such as unreacted glycerol, stearic acid and catalyst. These impurities must be removed through separation and purification to obtain high-purity monostearate glycerides. Commonly used separation methods include washing, salting out, crystallization, etc.

Drying and packaging: Finally, the resulting glyceryl monostearate is dried to remove the water and then packaged. The form of packaging, such as bags, bottles, or barrels, can be selected according to actual needs.

The advantages of chemical synthesis are high production efficiency, high product purity, and suitability for large-scale production. However, this method requires the use of a large number of organic solvents and catalysts, which may cause some pollution to the environment. Therefore, it is necessary to pay attention to environmental protection issues in the production process and strengthen the treatment and utilization of wastewater and waste residues.

Natural extraction method

The natural extraction method is a method of extracting glycerol monostearate from natural plants. Some plants naturally contain monostearin in their seeds, fruits, or leaves. Here are the steps of the natural extraction method:

Collect raw materials: Choose natural plants rich in glycerol monostearate, such as coconut oil, palm oil, soybean oil, etc. Collect the seeds, fruits or leaves of these plants as raw materials.

Extraction: The collected raw materials are broken or ground and then extracted using organic solvents such as petroleum ether, ether or methanol. The solvent can dissolve the glycerol monostearate and separate it from the raw material.

Separation and purification: The resulting solution contains glycerol monostearate and other impurities after extraction. It is necessary to remove impurities through separation and purification to obtain high-purity monostearate glycerides. Common separation methods include filtration, centrifugation and evaporation.

Drying and packaging: Finally, the resulting glyceryl monostearate is dried, the solvent is removed, and then packaged. The form of packaging, such as bags, bottles, or barrels, can be selected according to actual needs.

In addition, the glycerol monostearate extracted from natural plants has good natural biocompatibility and high application value in some fields, such as medicine and cosmetics. However, the natural extraction method's production efficiency is low, limited by factors such as plant growth region and season, and the cost is high. Therefore, it is necessary to comprehensively consider various factors for selection and application in actual production.
