What is the boiling point of propylene glycol?
What is the boiling point of propylene glycol?
370.8°F (188.2°C)Propylene glycol / Boiling point
What is the vapor pressure of glycol?
0.089 mg Hg
In pure form, ethylene glycol is a clear liquid. If released to the environment as a spill, it would have little tendency to evaporate into the atmosphere. The vapor pressure of ethylene glycol has been estimated as 0.089 mg Hg at 25°C.
What happens when you boil propylene glycol?
Propylene glycol does not decompose on heating, it simply boils.
Is propylene glycol the same as propylene glycol?
Propylene glycol is also used to create artificial smoke or fog used in fire-fighting training and in theatrical productions. Other names for propylene glycol are 1,2-dihydroxypropane, 1,2-propanediol, methyl glycol, and trimethyl glycol. Propylene glycol is clear, colorless, slightly syrupy liquid at room temperature.
What is the pH of propylene glycol?
9.3 to 10.5
Protein/propylene glycol alginate gels can be formed using 6% protein in a suitable 0.1 M buffer solution in the pH range 9.3 to 10.5.
What is another name for propylene glycol?
Other names for propylene glycol are 1,2-dihydroxypropane, 1,2-propanediol, methyl glycol, and trimethyl glycol. Propylene glycol is clear, colorless, slightly syrupy liquid at room temperature.
What is the vapor pressure of ethylene glycol at boiling point?
760 mmHg

What is the relationship between temperature and vapor pressure?
As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases as the temperature decreases.
What is the boiling point of glycerine?

What is difference between PG and PEG 400?
PG and PEG have dissimilar chemical structures. PG is a small, single molecule with 3 carbons and 2 OH groups ( ie a double alcohol). PEG is a multi-unit polymer with a differing molecular weight and backbone.
