Toluic aldehydes

At the end of three hours the reaction-product is poured into ice-water an oily layer separates, and the mixture is distilled with steam to remove tolncuc and toluic aldehyde. The aqueous distillate is shaken with saturated sodium bisulphite, aud undissolved toluene separated from the aqueous layer. If the aldehyde bisulphite separates at this stage it must be dissolved by adding more water. [Pg.154]

The three xylenes, electrolyzed in acetone and dilute sulphuric acid, yield principally the three toluic aldehydes, m-Xylene, even when sodium acetate and acetic acid are employed as electrolyte, gives the m-toluic aldehyde. [Pg.134]

Some 4-substituted aromatic aldehydes, such as anisic aldehyde, toluic aldehyde, or t-butylbenzaldehyde, are produced commercially. The electrosynthesis can be accomplished by several different methods and is a good example of the versatility of selective electrochemical oxidations [91]. [Pg.1286]

This is based "on the Gatterman/Koch reaction, which consists uTcarbonylating toluene to p-toluic aldehyde and then oxidizing the latter to terephthalic acid. [Pg.297]

The toluic aldehyde/HBF complex is then decomposed by heating between 130 and 180 C in the presence of a solvent (benzene). The BF3. HF and unconverted toluene are recovered and recycled. The o- and p-tohiic aldehydes are separated by crystallization. Purified p-toluic aldehyde is air-oxidized (in solution m acetic add) in the presence of manganese acetate, cobalt acetate and sodium bromide, by the technique employed for p-xylene. This takes place around 200°C, at 2.10 Pa absolute ... [Pg.298]
