# Evaporation rate of diethylene glycol monobutyl ether

## Evaporation rate of diethylene glycol monobutyl ether

(OP)
How do I calculate the evaporation rate (LB/HR) of diethylene glycol monobutyl ether in air at 68 F and at 200 F given:

Vapor Pressure: 0.06mm Hg @20C
Evaporation Rate: 0.01 (Butyl acetate =1)
Specific gravity of vapor= 5.6(air =1)

### RE: Evaporation rate of diethylene glycol monobutyl ether

Yes, I also need to know how to calculate evaporation rate of ethyl lactate.  All the MSDS sheets compare it to ether and say it's evap. rate is less than ether's or less than 1.  And here's my obvious question......What are the units on ether=1?  Even if I assume ethyl lactate has an evaporation rate of 1, worst case, what are the units?
