| abstract | 966,986. Aromatic carboxylic acids. SOCONY MOBIL OIL CO. Inc. April 4, 1961 [April 4, 1960], No. 12026/61. Heading C2C. Aromatic carboxylic acids are produced by contacting with an oxygen-containing gas a mixture of a methyl aromatic compound (otherwise not alkyl substituted) and a promoter comprising the structure (R is C 1-4 -alkyl) in a 0À1-10:1 weight ratio at a temperature from 50‹C. to the b.p. of the methylaromatic compound, a flow rate of said gas per 100gm. total alkylaromatic compounds of 0À1-4 cu. ft./hr. oxygen and for 0À5-10 hrs. The preferred promoter is cumene (although diisopropyl benzene and p-cymene are also mentioned) and an oxidation catalyst such as cobalt naphthenate or iron phthalocyanine may also be used. Specified methylaromatic compounds are toluene, the xylenes, hemimellitene, pseudocumene, mesitylene, 1- and 2-methylnaphthalenes, dimethylnaphthalene, the toluic and xylic acids, methylpyridine, p-chlorotoluene, tolunitrile. In examples acetophenone is obtained as a by-product, presumably by oxidation of cumene. |
