boiling point of isopropyl alcohol and water

calculating flashpoint of 5% (v/v water) isopropyl alcohol

5/19/2003Data I have for isopropyl alcohol indicates it alone has a flash point of about 12C I would suspect a 5vol% solution in water would be higher You might could find that a supplier produces such a mixture and get the info you need from their MSDS

Pressure vs Temperature (boiling point)

Boiling Points and Vapor Pressure Background 2 As a very general rule of thumb the boiling point of many liquids will drop about 0 5˚C for a 10mmHg decrease in pressure when operating in the region of 760 mmHg (atmospheric pressure) At lower pressures a 10 ˚C drop in boiling point can be observed for each halving of the pressure
