3.7 Acetylation

Various processes thereby produce a by-product which is of other important industrial use. Like in the case of biodiesel manufacturing using methanol, we get a secondary by-product called glycerol. It is a very good raw material for the process called acetylating as in this process, especially when carried out in reactive distillation column, it is reported that about 99% conversion of glycerol into triacetin is observed. This triacetin acts as an additive in compression engine fuels and reduced the knocking in the engine.
