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
Lower flammability limits for many organic materials are in the range of 10–50 g/m 3, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds of this concentration are hard to see through for more than a short distance, and normally only exist inside process equipment.
There is a difference in the mixing ratio, depending on whether it is ethylene glycol or propylene glycol. For ethylene glycol, the mixing ratios are typically 30/70 and 35/65, whereas the propylene glycol mixing ratios are typically 35/65 and 40/60. It is important that the mixture be frost-proof at the lowest operating temperature. [24]

The main component of deicing fluid is a freezing point depressant (FPD), usually propylene glycol or ethylene glycol. Other ingredients vary depending on the manufacturer, but the exact composition of a particular brand of fluid is generally held as confidential proprietary information.
Poses no health hazard, requires no precautions, and would offer no hazard beyond that of ordinary combustible materials (e.g., wood, sugar, salt, propylene glycol) 1: Exposure would cause irritation with only minor residual injury (e.g., acetone, sodium bromate, potassium chloride) 2
The flammable nature of the exhalations of wine was already known to ancient natural philosophers such as Aristotle ... (OH)CH 2 OH (propylene glycol). ...
It is flammable and explosive. It is shock-sensitive and burns with a clean flame producing water vapor, carbon monoxide, and nitrogen gas. C 3 H 6 (ONO 2) 2 → 3 CO + 3 H 2 O + N 2. The principal current use of propylene glycol dinitrate is as a propellant in Otto Fuel II, together with 2-nitrodiphenylamine and dibutyl sebacate.
