Since a difficult fractionation may consume days, during which the pot is at constant reflux, heed must be paid to considerations of thermal stability in the distilland, especially since small quantities of acids or bases can, and do accelerate thermal degradation of some organic chemicals. In fact, some thermal decompositions have been shown to be autocatalytic. It therefore may be well to consider flash distillation of the crude product prior to subjecting it to fractional distillation to remove trace non-volatiles and/or non-volatiles which would accelerate decomposition or lead to excessively high pot temperatures. In some cases one might consider the addition of a stabilizing agent to the pot to retard decomposition.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming.
