Barium propionate is the barium salt of propionic acid .
Manufacturing
Barium propionate can be prepared by reaction of barium hydroxide are shown with propionic acid.
properties
Barium propionate forms different hydrates: a monohydrate, which gives off its water of crystallization at 110 ° C, a tri- and a hexahydrate.
When heated dry to 460 ° C, barium propionate decomposes into 3-pentanone and barium carbonate .
