1. colorless, transparent, odorless, viscous liquid, sweet, hygroscopic. With water and alcohols, amines, phenols miscible in any proportion, the aqueous solution is neutral. Was dissolved in ethyl acetate 11 times, about 500 times that of diethyl ether. Not soluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether, oils, long-chain fatty alcohols. Combustible, the case chromium dioxide, potassium chlorate and other strong oxidants can cause a fire and explosion. Is also a good solvent for many inorganic salts and gases. Non-corrosive metal integrity management quality assurance industrial glycerin, used as a solvent can be oxidized to acrolein. Chemical properties: esterification reaction with an acid, such as alkyd resins and phthalic acid ester generated. Esters with an ester exchange reaction occurs. Chlorohydrin reaction with hydrogen chloride. Dehydration of glycerol in two ways: intermolecular dehydration diglycerin and polyglycerin; intramolecular dehydration to give acrolein. The reaction of glycerol with an alkali alcoholate. With an aldehyde, a ketone reacted with an acetal ketal. Generate glyceraldehyde and dihydroxyacetone with dilute nitric acid oxidation; formic acid and formaldehyde by periodate oxidation. Chromic anhydride with strong oxidizing agents, such as potassium chlorate or potassium permanganate contact, can cause a fire or explosion. Glycerin can also play a role, such as nitrification and acetylation. 2. non-toxic. Even if the drink into a dilute solution reached a total of 100g harmless, after hydrolysis and oxidation in the body as a nutrient source. In animal experiments, such as a very large number so that when drinking, the alcohol having the same anesthetic effects. 3. The presence in flue-cured tobacco, burley tobacco, oriental tobacco tobacco smoke. 4. naturally present in tobacco, beer, wine, cocoa. Glycerin: scientific name (glycerol). Colorless, odorless and has a sweet, viscous liquid. Density 1.2613, boiling point 290 ° C (decomposition). Melting point of 17.9 ° C. Can be used with any water miscible and proportions, can reduce the freezing point of water. Great hygroscopicity. Slightly soluble in alcohol and ether, insoluble in chloroform. When generating double glycerol dehydration, polyglycerol. Generate glyceraldehyde, glycerol acid oxidation. Reduction when generating propylene glycol. Heating with sulfuric acid to produce acrolein. And can play a role in digestion and acetylation. For the manufacture of nitroglycerine, alkyd resins and grease gum. Liquid fuels used for aircraft and automotive antifreeze, cellophane plasticizers, as well as cosmetics, leather, tobacco, textiles, and other hygroscopic agent.
