A combination reflux/distillation apparatus is provided having interchangeable reflux and distillation columns, a segmented collection trough and an integrated indirect heating provision. The apparatus is uniquely adapted for refluxing and distilling small quantities of materials without the losses attendant to...
Method and apparatus for production of hydrogen cyanide by catalytic cleavage of formamide The reaction conditions for the one-step synthesis of purine by heating formamide were investigated. Purine was formed as a main product when formamide was heated at 175-185° in a sealed vessel ; reaction ...
Byirontoenail— On Dec 06, 2011 @Mor - Actually, distillation was interesting to me because it was one of the few things we did in chemistry that I could directly relate to real life. In lots of different ways, too, although since I was a bit of a capitalist when I was a student,...
Cooling apparatus around condenser You can think of a reflux condenser somewhat like putting a lid on a pot of boiling water. The water never exceeds its boiling point temperature while in liquid form, but gaseous water can become far hotter than 212° F. The pot lid's temperature is lower...
