Application;
Glycerol (also called glycerine or glycerin) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in all lipids known as triglycerides. It is widely used in the food industry as a sweetener and humectant . Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.
Application
1. Used for manufacturing alkyd and epoxy resins.
2. In medicine, it is used to prepare various preparations, solvents, hygroscopics, antifreeze, and sweeteners, and to prepare external ointments or suppositories.
3. Used in the paint industry to produce various alkyd resins, polyester resins, glycidyl ethers, and epoxy resins.
4. Used in the textile and printing and dyeing industries to produce lubricants, hygroscopics, fabric anti shrink treatment agents, dispersants, and penetrating agents.
5. Used as a sweetener, moisture absorber, and solvent in the food industry.
6. It has a wide range of applications in industries such as papermaking, cosmetics, leather making, photography, printing, metal processing, electrical materials, and rubber.
7. And used as fuel for automobiles and airplanes, as well as antifreeze in oil fields.
8. Glycerin can be used as a plasticizer in the new ceramic industry.
