Abstract

Phloroglucinol is prepared by hydrogenating trinitrobenzene or trinitobenzoic acid, preferably under pressure, in a solution in a solvent containing at least 10% by weight of the trinitrobenzene compound and in the presence of a hydrogenation catalyst at a temperature of at least 40 DEG C., separating the catalyst and solvent from the hydrogenated mixture, hydrolysing the hydrogenated mixture with acid and recovering phloroglucinol from the resulting mixture. Suitable solvents are, for example, ketones, alcohols, esters and ethers. The preferred catalyst is Raney nickel but other catalysts may be used, e.g. platinum, palladium and platinum oxide. Triaminobenzene and triaminobenzoic acid are formed as intermediates by the catalytic hydrogenation of trinitrobenzene and trinitrobenzoic acid respectively.
