The Effect of Isopropyl Alcohol

Isopropyl alcohol solvent has already widely used as reaction medium in CMC synthesis process Mixing 2-butanol with isopropyl alcohol is expected to result in lower polarity of reaction medium and then obtain higher DS value because 2-butanol has lower polarity than isopropyl alcohol [28]

Confusion about mixing methanol/water

23 03 2009Hi Just read the thread about water/methanol calculator and it has got me confused As buying washer fluid here in the UK is going to make the system to expensive to run (8 for 5 litres) I have purchased 20 litres of 99 9% methanol My question is in the mixing as the thread mentions mixing it by weight rather than by volume is this what I should be doing ?
