Opis

Opis ogólny

Butanol, alcohol with higher energy density, lower vapour pressure and low hygroscopicity. 1-Butanol is a potential fuel substitute to gasoline. It is also a feedstock used to produce chemicals. It is produced via two pathways, the synthetic 2-ketoacid pathway and CoA-dependent pathway. It can also be produced by fermentation of biomass-derived carbohydrates.

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food.
