The "Golden Rule" for Solvent Removal

To achieve optimal distillation conditions, the distillation energy supplied by the heating bath must be removed by the condenser. An easy concept to remember for solvent removal via rotary evaporation is the 20/40/60 Rule. These numbers refer to the D20ºC principle. Since Buchi invented the Rotary Evaporator 50 years ago, Buchi has

Vacuum distillation in petroleum refining. Petroleum crude oil is a complex mixture of hundreds of different hydrocarbon compounds generally having from 3 to 60 carbon atoms per molecule, although there may be small amounts of hydrocarbons outside that range. The refining of crude oil begins with distilling the incoming crude oil in a so-called atmospheric distillation column operating at .
