Abstract

A method for manufacturing 3-hydroxy-3-methylbutanoic acid (HMB) in commercially viable amounts is disclosed. The reaction mixture cycles through an external heat exchanger while the primary reactant is added in a warmer so as to control and maintain a low temperature for the reaction mixture. The manufacturing process herein disclosed increases yield while decreasing reaction time from the synthetic processes currently practiced.
