Preparation of Glycerol: This chemical can be prepared by saponification of fats, e.g. a byproduct of soap-making.

Preparation of Glycerin

Uses of Glycerol: This chemical is used as a humectant, solvent and sweetener, and may help preserve foods in foods and beverages. And it can be used as emulsifiers to manufacture mono- and di-glycerides, as well as polyglycerol esters going into shortenings and margarine. Additionally, it is used as a humectant in the production of snus, in medical and pharmaceutical and personal care preparations. It is also used as a tablet holding agent in solid dosage forms like tablets. And it can be used orally to eliminate halitosis, as it is a contact bacterial desiccant. Furthermore, it has been used as a substitute for ethanol as a solvent in preparing herbal extractions. It is a common component of solvents for enzymatic reagents in the laboratory. It is also used to produce nitroglycerin, or glycerol-trinitrate.

When you are using this chemical, please be cautious about it as the following: it is highly Flammable. It is also harmful by inhalation, in contact with skin and if swallowed. And it is irritating to the eyes.In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Moreover, you should wear eye/face protection. And please avoid contact with skin and eyes.

People can use the following data to convert to the molecule structure.
(1)Canonical SMILES: C(C(CO)O)O
(2)InChI: InChI=1S/C3H8O3/c4-1-3(6)2-5/h3-6H,1-2H2
