Preparation of pyruvic acid from tartaric acid?

Answer 1

on heating the tartaric acid, the tartaric acid forms a keto acid which is known as pyruvic acid

C4H6O6 ------KHSO4/heating------> C3H4O3

(tartaric acid) (Pyruvic acid)

Answer 2

Pyruvic acid can be prepared from tartaric acid through a process called pyrolysis, where tartaric acid is heated under controlled conditions to break down into pyruvic acid and other byproducts. The pyruvic acid can then be isolated and purified from the reaction mixture using various separation techniques.
