| titleOfInvention | Process for the preparation of a composition comprising meso-tartaric acid |
| abstract | The present invention relates to a process for the preparation of a composition comprising tartaric acid wherein 55 to 90% by weight of said tartaric acid is mesotartaric acid, said process comprising: (i) 35 to 65% by weight of a dialkali metal salt of L-tartaric acid, D - a mixture of a dialkali metal salt of tartaric acid, L-tartaric acid, D-tartaric acid and, optionally, a dialkali metal salt of meso-tartaric acid, and an aqueous mixture comprising from 2 to 15% by weight of an alkali metal or alkaline metal hydroxide Preparing; And (ii) stirring and heating the aqueous mixture to a temperature between 100 ° C and its boiling point until 55-90% by weight of the tartaric acid is converted to meso tartaric acid. |
