TOLUALDEHYDES 화학적 특성, 용도, 생산

• 화학적 성질

  Tolualdehydes, mixed o-, m-, p-, have a sweet and herbaceous odor reminiscent of bitter almond.

  Reported found in roasted nuts, tomato, cooked beef, beef fat, cider, coffee, tea and elderberry juice.

• 용도

  Perfumes, pharmaceutical and dyestuff intermediate, flavoring agent.

• 제조 방법

  By oxidation of o-, m-, or p-xylene (chemical or electrolytical oxidation).

• 신진 대사

  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).
