Product Description

Product Description

 

           Glycerin, also known as glycerin, is an organic compound with the chemical formula C3H8O3 and a simple polyol compound. It is a colorless, odorless, sweet, viscous liquid that is non-toxic. The glycerol backbone is found in lipids called glycerides. Because of its antibacterial and antiviral properties, it is widely used in FDA-approved wound and burn treatments. Conversely, it is also used as a bacterial culture medium . It serves as an effective marker of liver disease. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations. Due to its three hydroxyl groups, glycerin is miscible with water and hygroscopic .

 

Properties and Stability

   Molar refractive index: 20.51
   Molar volume (cm3/mol): 70.9 cm3/mol
   Isotonic specific volume (90.2 K): 199.0
   Surface tension: 61.9 dyne/cm
   Polarizability (10-24 cm3): 8.13

 

1. Colorless, transparent, odorless, viscous liquid with sweet taste and hygroscopicity. It is miscible with water, alcohols, amines and phenols in any proportion, and the aqueous solution is neutral. Soluble in 11 times of ethyl acetate and about 500 times of diethyl ether. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether, oils, and long-chain fatty alcohols. It is flammable and can cause combustion and explosion when exposed to strong oxidants such as chromium dioxide and potassium chlorate. It is also a good solvent for many inorganic salts and gases. It is non-corrosive to metals and can be oxidized to acrolein when used as a solvent.

2. Chemical properties: esterification reaction with acid, such as esterification with phthalic acid to form alkyd resin. Transesterification occurs with esters. Reacts with hydrogen chloride to form chlorohydrins. There are two ways to dehydrate glycerol: intermolecular dehydration to obtain diglycerol and polyglycerol; intramolecular dehydration to obtain acrolein. Glycerol reacts with alkali to form alcoholate. Reacts with aldehydes and ketones to form acetals and ketals. Oxidation with dilute nitric acid produces glyceraldehyde and dihydroxyacetone; oxidation with periodic acid produces formic acid and formaldehyde. Contact with strong oxidants such as chromic anhydride, potassium chlorate or potassium permanganate can cause combustion or explosion. Glycerol can also play a role in nitration and acetylation.

3. Non-toxic. Even if a total amount of 100 g of dilute solution is drunk, it is harmless. It is hydrolyzed and oxidized in the body and becomes a nutrient source. In animal experiments, it has the same anesthetic effect as alcohol when consumed in extremely large amounts.
