Explanation of BU

7/1/2002Evaporation Rate One general reference material for evaporation rates is n-butyl acetate (commonly abbreviated BuAc) Whenever a relative evaporation rate is given the reference material must be stated Taking the relative evaporation rate of butyl acetate as 1 0 Other materials are then classified as: Speed Evaporation Rate (BuAc = 1 0) Examples

How do I evaporate DMSO from a drug?

3/13/2008I had evaporated the isopropyl/water and recovered some powder but then I was told (at least as far as I interpreted his instructions) that we needed to wash the other vials with 20% DMSO to gather up whatever powder was there and collect it all into one vial Which I did but I found that DMSO isn't evaporating when I pass air into the solution

What are the 6 factors that affect evaporation?

5 Rate of evaporation depends upon the nature of the liquid for example petrol evaporates faster than water 6 Vapor pressure: if pressure is applied on the surface of a liquid evaporation is hindered consider for example the case of a pressure cooker
