CHROMATOGRAM DATA

SOURCE

Milk and milk products. Can be obtained from wood pulp waste liquor by a fermentation process using bacteria of the genus Propionibacterium.(Ref. 1008) From natural gas by the Fischer-Tropsch process;as a byproduct in the pyrolysis of wood; by the action of microorganisms on a variety of materials in small yields. Very pure propionic acid can be obtained from propionitrile.

CHEMICAL SYNTHESIS

Preparation from ethylene,carbon monoxide and steam.(Ref. 1009)(Ref. 1010)From ethanol and carbon monoxide using a boron trifluoride catalyst.(Ref. 1011)By oxidation of propionaldehyde(Ref. 1012)
