Production Method of Glyceryl Monooleate  :

Chemical synthesis

Chemical synthesis is the main method for the industrial production of glycerol monooleate. The method is usually based on raw materials such as glycerol, oleic acid, and catalysts, and glycerol monooleate is synthesized through a series of chemical reactions.

Raw material preparation: Glycerin can be refined by industrial-grade glycerin. Oleic acid is usually selected from natural plant or animal oleic acid, and the catalyst can be acidic or alkaline.

Esterification reaction: glycerol and oleic acid are esterified under the catalyst to produce glycerol monooleate. The esterification reaction is usually carried out at a certain temperature and pressure to promote the reaction. The selection of a catalyst greatly influences the efficiency and purity of the esterification reaction.

Separation and purification: The generated glycerol monooleate must be separated from the reaction liquid at the end of the reaction. Common separation methods include centrifugal separation, filtration, and extraction. After separation, the glycerol monooleate also needs to be refined and purified to remove the residual raw materials and catalysts to improve the purity and quality of the product.

Dry packaging: Finally, the final glycerol monooleate product is obtained after drying and packaging processes. Drying can use vacuum drying, spray drying, and other methods; packaging, generally in bags or bottles, is selected according to the requirements of the product.

Chemical synthesis has the advantages of mature technology, high yield, and low cost, so it is currently the main method of producing glycerol monooleate industrially. However, chemical synthesis 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.

Biological fermentation method

Biological fermentation is another method of preparing glycerol monooleate, which converts glycerol into glycerol monooleate by microbial fermentation. 

Strain selection and culture: The biological fermentation method must select microbial strains that produce glycerol monooleate, such as pseudomonas, yeast, etc. Under sterile conditions, the bacteria are inoculated into the medium for culture, providing suitable growth conditions such as temperature, pH value and nutrients, so the microorganisms multiply.

Fermentation: During microbial culture, various enzymes are secreted, including enzymes that catalyze glycerol conversion to monooleate. Under suitable conditions, these enzymes can convert glycerol into the target product glycerol monooleate. The fermentation process can be optimized by controlling temperature, pH, and stirring speed.

Separation and purification: The glycerol monooleate produced needs to be separated from the fermentation solution after fermentation. Common separation methods include centrifugal separation, filtration, and extraction. The separated glycerol monooleate must also be refined and purified to remove impurities and other microbial metabolites.

Dry packaging: Finally, the final glycerol monooleate product is obtained after drying and packaging processes. Drying can use vacuum drying, spray drying, and other methods; packaging, generally in bags or bottles, is selected according to the requirements of the product.
