for the flavour and fragrances industry and for chemical syntheses

An exclusive agreement with Celanese Europe enables PERGAN to drum Acetaldehyde into small vessels. This activity primarily adds value to the supply chains of the flavour and fragrances industry.

Acetaldehyde is highly reactive intermediate and produced by catalytic oxidation from ethylene. It is an important intermediate in many chemical syntheses. Acetyldehyde is a flammable, clear, colorless liquid with a pungent odor and miscible in any ratio with water and the usual organic solvents.
