1.Physical and chemical properties of Glycerine
Glycerine, also known as glycerin, is an organic compound, chemical formula for C3H8O3, CAS No.: 56-81-5, colorless and odorless transparent viscous liquid. It can absorb moisture from the air and hydrogen sulfide, hydrogen cyanide and sulfur dioxide. It is miscible with water, alcohols, amines and phenols in any proportion, but insoluble in benzene, chloroform, carbon disulfide, carbon tetrachloride, petroleum ether and oil.
2.The production of Glycerine raw materials
1.Made from natural oils and fats as raw materials, known as natural Glycerine. About 42% of the natural glycerin from the soap by-products, 58% from the production of fatty acids;
2.To propylene as raw material synthesis, known as synthetic glycerol. Glycerine synthesized from propylene in a variety of ways can be summarized into two categories, namely, chlorination and oxidation.
3.The role and use of propylene Glycerine
1.Used in the production of epichlorohydrin, 1,2-propanediol, 1,3-propanediol, ethylene glycol, dihydroxyacetone and so on.
2.It is used to produce various alkyd resins, polyester resins, glycidyl ethers and epoxy resins in the coating industry.Alkyd resin made of glycerol as raw material is one of the good Coating Intermediates, which
