Welcome to inquire! Contact: Feng Zhongying. Natural glycerin production of glycerol, glycerin byproduct of all animal and plant fat recovered from the soap in 1984 ago. Until now, the production of natural oils remains the main raw material glycerol, groups of about 42% was natural homemade soap byproduct glycerol, 58% derived from fatty acid production. Soap industry saponification of fat. Saponification reaction product into two layers: an upper layer mainly containing fatty acid sodium salt (soap) and a small amount of glycerin glycerin glycol, the lower is the waste lye, containing salts, glycerin dilute solution of sodium hydroxide, typically containing glycerol 9-16 % pharmaceutical grade glycerine, salts 8-20%. Grease reaction. Glycerin water (also called sweet water) fat hydrolysis, and its high content of glycerin soap waste than about 14-20% inorganic salt 0-0.2%. Has been widely used in recent years, continuous high-pressure hydrolysis reaction without using a catalyst, and the resulting sweet generally free of inorganic acid triglycerides, purification method is simpler than waste lye. Whether the amount of glycerol Glycerol soap waste water, or the hydrolysis of oils and fats contained in not high, and both contain a variety of impurities, natural glycerin production process including purification, and concentrated to give the crude glycerin, and crude glycerin distillation, bleaching, deodorization refining process. This is the most important synthetic glycerol production process includes four steps, namely, high temperature chlorination of propylene, allyl chloride hypochlorous acid, hydrolysis and saponification dichloropropanol epichlorohydrin. Epichlorohydrin hydrolysis of glycerol at 150 ℃, carbon dioxide under pressure 1.37MPa, the aqueous solution of 10% sodium hydroxide and 1% sodium carbonate is carried out to produce an aqueous solution of glycerol Glycerol content of 5-20%, containing sodium chloride was concentrated, desalted, distilled to give a purity of 98% or more glycerol.
