| | TOLUALDEHYDES Usage And Synthesis |
| Chemical Properties | Colorless liquid. Slightly soluble inwater;
soluble in alcohol and ether. There are also oand
misomers. Combustible. | | Chemical Properties | Tolualdehydes, mixed o-, m-, p-, have a sweet and herbaceous odor reminiscent of bitter almond. | | Occurrence | Reported found in roasted nuts, tomato, cooked beef, beef fat, cider, coffee, tea and elderberry juice. | | Uses | Perfumes, pharmaceutical and dyestuff intermediate,
flavoring agent. | | Preparation | By oxidation of o-, m-, or p-xylene (chemical or electrolytical oxidation). | | Taste threshold values | Taste characteristics at 15 ppm: cherry pit, coumarin, almond, sweet, with a slight powdery hay and vanillalike
nuance. | | Metabolism | Aromatic aldehydes are oxidized in vivo almost entirely to the corresponding acid. Thus, in rabbits, p-tolualdehyde is converted to p-toluic acid which has been detected in the urine as the ester glucuronide (Williams, 1959). p-Tolualdehyde was oxidized to p-toluic acid by resting cells of Pseudomonas aeruginosa (Omori & Yamada, 1970). Perillaldehyde dehydrogenase, isolated from a soil pseudomonad, catalysed the oxidation of m- and p-tolualdehyde but not of o-tolualdehyde (Ballal, Bhattacharyya & Rangachari, 1967). The reduction of p-tolualdehyde by NADH was catalysed by horse-liver alcohol dehydrogenase (Blomquist, 1966) and by yeast alcohol dehydrogenase at pH 8.5-9.5 (Klinman, 1975). A non-specific NADPH-linked aldehyde reductase isolated from various areas of bovine brain also catalysed the reduction of p-tolualdehyde (Tabakoff & Erwin, 1970). |
