Propylene glycol Usage
Used as raw materials of resin, plasticizer, surfactant, emulsifier and demulsifier, and also used as antifreeze and heat carrier
Used as gas chromatography stationary liquid, solvent, antifreeze, plasticizer and dehydrating agent
Uses: Used as a carrier solvent for gas chromatography fixatives, solvents, antifreezes, plasticizers and dehydrating agents; wetting agents; moisturizers; anticaking agents; antioxidants; tissue modifiers; surfactants; stabilizers; thickening Dough regulators; emulsifiers; flavoring agents; excipients; processing aids. GB2760~96 are listed as food processing aids. It is mainly used as a solvent for various spices, pigments, preservatives, and an extraction solvent for vanilla beans, roasted coffee grains, and natural flavors. Moisturizing and softening agent for candy, bread, packaged meat, cheese, etc. It can also be used as an anti-mold additive for noodles and filling cores. Adding 0.006% to soymilk can make the flavor unchanged when heated, and make white and shiny packaged tofu, which will increase in volume when fried.
Purpose Propylene glycol is an intermediate of the fungicide difenoconazole. Use as a solvent to dissolve insoluble food additives such as preservatives, pigments, antioxidants, etc., and then add to food; it has strong hygroscopicity and has moisturizing and antifreeze effects on food. my country stipulates that it can be used in cakes, and the maximum use amount is 3.0g/kg.
Purpose Propylene glycol is an important raw material for unsaturated polyester, epoxy resin and polyurethane resin. The amount in this area accounts for about 45% of the total consumption of propylene glycol. This unsaturated polyester is used in large quantities for surface coatings and reinforced plastics. Propylene glycol has good viscosity and hygroscopicity, and is non-toxic, so it is widely used as a moisture absorbent, antifreeze, lubricant and solvent in the food, medicine and cosmetic industries. In the food industry, propylene glycol and fatty acids react to produce propylene glycol fatty acid esters, which are mainly used as food emulsifiers; propylene glycol is an excellent solvent for seasonings and pigments. In the pharmaceutical industry, propylene glycol is often used as a solvent, softener, and excipient in the manufacture of various ointments and ointments. Because propylene glycol has good mutual solubility with various spices, it is also used as a solvent and softener for cosmetics. Propylene glycol is also used as a tobacco moisturizer, antifungal agent, food processing equipment lubricants and food marking ink solvents. An aqueous solution of propylene glycol is an effective antifreeze.
Uses as a drug carrier and granular medicine. It can be used as humectant, softener, solvent, etc. in cosmetics. In the tobacco industry, it can be used as tobacco flavor, tobacco moisturizer, preservative, etc. In the food industry, it is used as a solvent for flavors, food colorings, food packaging softeners, and food anti-sticking agents. It can also be used to produce unsaturated polyester resins, plasticizers, dehydrating agents, surfactants, curing agents, binder materials, etc. for plastics. It can also be used in paint, pesticide, coating and other industries
Application Aviation deicing fluid, refrigerant and antifreeze, food and fragrance, fragrance, cosmetics and personal health products, heat transfer fluid, hydraulic and brake fluid, paint and coating, pet food/animal feed, medicine, polyurethane, non-toxic Saturated polyester resin, etc.
Use solvent, organic synthesis, antifreeze, plasticizer, bactericide. Gas chromatography analysis standard. Gas chromatographic stationary liquid (maximum operating temperature 150℃, solvent is chloroform), separation and analysis of alcohols, esters and ketones.
Propylene glycol Chemical properties
colorless, viscous and stable water-absorbing liquid, almost odorless and odorless. Miscible with water, ethanol and many organic solvents.
Propylene glycol production method
1. Direct hydration of propylene oxide is a pressurized non-catalytic hydrolysis method. It is prepared by direct hydration of propylene oxide and water at 150-160°C and 0.78-0.98MPa pressure. The reaction product is evaporated and rectified to obtain the finished product.
2. Indirect hydration of propylene oxide is prepared by indirect hydration of propylene oxide and water with sulfuric acid as a catalyst. 3. Direct catalytic oxidation of propylene.
