| titleOfInvention | Continuous process for the oxidation of organic compounds |
| abstract | The process for the oxidation of cyclic mono-nuclear compounds of aromatic nature containing oxidisable side chains to the corresponding carboxylic acids, described in the parent Specification is applied to compounds derived from naphthalene and quinoline. Examples of oxidisable side chains are alkyl groups, e.g. methyl, ethyl and isopropyl groups, hydroxyalkyl groups, esterified hydroxyalkyl groups, haloalkyl groups, dihaloalkyl groups, aldehyde groups and keto groups. The naphthalene or quinoline compound may also contain inert substituents such as halogen atoms, especially chlorine and bromine atoms, nitro groups, carboxylic groups and sulphonic acid groups. Suitable starting materials are 1-methylnaphthalene, 2-methylnaphthene, the various dimethylnaphthalenes, 2-methylquinoline, 4-methylquinoline, 5-nitro -4- methylquinoline, 3-bromo -8- methylquinoline, 1, 8-dimethylnaphthalene-sulphonic acid-(2), 2-methyl-1-hydroxymethyl-naphthalene, 2-methyl-1-chloromethylnaphthalene and 2-methylquinoline aldehyde-(5). In examples (1) 2-methylnaphthalene is reacted in a tantalum lined reactor in the presence of steam with 20% nitric acid at 260 DEG C. and 75 atmospheres pressure to produce b -naphthoic acid; (2) 4-methylquinoline is reacted with 40% nitric acid at 250 DEG C. and 80 atmospheres pressure to produce quinoline-4-carboxylic acid. |
