Title: A process for the production of butane-1,2,4-tricarboxylic acid
IPC: C07C51/16
Filed: 1955-04-13
Abstract: Butane-1,2,4-tricarboxylic acid is produced by oxidizing hexahydro-p-hydroxybenzoic acid or an ester thereof by means of nitric acid or potassium permanganate.  The reaction may be effected in the presence of ammonium vanadate as a catalyst.  The oxidation with nitric acid is preferably effected at 65-100 DEG  C. with a concentration of nitric acid of not less than 60 per cent. The oxidation with permanganate is preferably effected at - 5 to + 25 DEG C.  The product may be purified by dissolving in ethyl acetate and crystallizing out the butane-1,2,4-tricarboxylic acid by adding petrol ether.  The product may also be esterified with lower paraffin alcohols and fractionally distilled.  Examples are given of the oxidation of hexahydro-p-hydroxy benzoic acid and its ethyl and n-propyl esters with nitric acid in the presence of ammonium vanadate.  The ethyl ester is also oxidized by means of potassium permanganate with addition of potassium hydroxide.
