8.9: Distillation - Chemistry LibreTexts

Feb 20, 2022 Distillation is a process whereby a mixture of liquids having different vapor pressures is separated into its components. At first one might think that this would be quite simple: if you have a solution consisting of liquid A that boils at 50 C and liquid B with a boiling point of 90 C, all that would be necessary would be to heat the mixture to some temperature between …

oxidant to free cyanide. Conversely, a negative bias can occur when SCN is decomposed in the absence of oxidants, forming volatile carbonyl sulfide, which is converted to sulfide upon absorption in an alkaline liquid. For manual total cyanide distillation analysis use the BC MOE HCl-HH method (Ref. 13) to mitigate thiocyanate interference.

How Is Isopropyl Alcohol Made? - Sciencing

Propene is one of the basic materials necessary to produce isopropyl alcohol. This compound comes from fossil fuels—petroleum, natural gas and even coal. Through oil refining, fossil fuels break down into component substances; propene is one of the byproducts.
