Contents
Properties
Chemical
Calcium propionate reacts with strong acids to eliberate propionic acid
Physical
Calcium propanoate is a white crystalline solid, soluble in water, but less so in organic solvents.
Availability
Calcium propionate is sold in some food stores as preservative.
It can also be bought online cheap.
Preparation
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.
Projects
- Food preservative
- Make propanoic acid
Handling
Safety
Calcium propionate has low toxicity and it's approved as food preservative.
