Calcium propionate or calcium propanoate is the calcium salt of propanoic acid.
Calcium propionate reacts with strong acids to eliberate propionic acid
Calcium propanoate is a white crystalline solid, soluble in water, but less so in organic solvents.
Calcium propionate is sold in some food stores as preservative.
It can also be bought online cheap.
Calcium propionate can be prepared by reacting propionic acid with calcium hydroxide.
The haloform reaction between calcium hypochlorite and methyl ethyl ketone gives calcium propanoate. Purification of calcium propanoate however, is difficult due to the large amounts of impurities and side products.
- Food preservative
- Make propanoic acid
Calcium propionate has low toxicity and it's approved as food preservative.
In closed bottles, away from strong acidic vapors.
No special disposal is required, can be poured down the drain or dumped in trash.
