Question

What happen when butanenoic acid is heated with soda lime at 630k??

Answer 1

Soda lime has much less tendency to absorb water. The solid sodium salt of a carboxylic acid is mixed with solid soda lime, and the mixture is heated. ... You can think of this as first a reaction between the acid and the soda lime to make sodium benzoate, and then a decarboxylation as in the first example.
