Now this may seem a stupid question, but as my old dad said there are no stupid questions only stupid answers!
I am distilling some liquid which has a boiling point of about 190 C, I have put the liquid under vacuum of -1bar and the liquid now boils at about 160C, I would like the liquid to boil at about 140C, so is it possible to put the liquid under a vacuum of say 1.5 Bar? The reason I ask is that when I look at vacuum pumps available off the shelf they seem to stop at – 1bar is this something to do with the fact that the surface pressure at the surface of the Earth is about 1 Bar? Or am I seeing complications where there are no complications.
Oh and this is my first posting so be gentle with me.
Thanks pjwt
