Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid.It is almost odorless and has a faintly sweet taste. Its chemical formula is CH 3 CH(OH)CH 2 OH. . As it contains two alcohol groups, it is classified as a d
Another example is propane-1,2-diol, or alpha propylene glycol, HO−CH 2 −CH(OH)−CH 3, used in the food and medicine industry, as well as a relatively non-poisonous antifreeze product. On commercial scales, the main route to vicinal diols is the hydrolysis of epoxides .
1,3-Propanediol is the organic compound with the formula CH 2 (CH 2 OH) 2. This 3-carbon diol is a colorless viscous liquid that is miscible with water. Products

One U.S. FAA-approved deicing fluid (Kilfrost DF Sustain) is 1,3-propanediol, a fermentation product of corn, as a freezing point depressant instead of ethylene glycol or propylene glycol. [19] Benzotriazole (and tolyltriazoles), although not highly toxic, is not readily degradable and has a limited sorption tendency.

They are named using suffixes -diol, -triol, etc., following a list of the position numbers of the hydroxyl groups, as in propane-1,2-diol for CH 3 CH(OH)CH 2 OH (propylene glycol). Example alcohols and representations
Propylene glycol dinitrate (PGDN, 1,2-propylene glycol dinitrate, or 1,2-propanediol dinitrate) is an organic chemical, an ester of nitric acid and propylene glycol. It is structurally similar to nitroglycerin , except that it has one fewer nitrate group.
