化学的特性

clear light yellow to amber liquid, insoluble in water, soluble in alcohol, benzene, toluene and other organic solvents.

使用

3-phenoxybenzaldehyde is an important intermediate for the synthesis of pyrethroid pesticides phenothrin, cypermethrin, deltamethrin,fenvalerate, fenpropathrin, flucythrinate, cyhalothrin, etc.

製造方法

Synthesis of 3-Phenoxybenzaldehyde: 3-phenoxybenzoic acid is generated by catalytic oxidation of 3-phenoxytoluene, followed by electrolytic reduction to obtain Phenoxybenzyl alcohol , and then selective oxidation with sodium hypochlorite to obtain 3-Phenoxybenzaldehyde.

一般的な説明

Enantioselective autoinduction during asymmetric hydrocyanation of 3-phenoxybenzaldehyde catalyzed by cyclo[(R)-phenylalanyl-(R)-histidyl] has been investigated. It undergoes hydrogenation catalyzed by Au/Pt bimetallic core/shell nanoparticles to yield 3-phenoxyphenyl methanol.

安全性プロファイル

Moderately toxic by intraperitoneal route. When heated to decomposition it emits acrid smoke and irritating vapors.

Degradation

3-Phenoxybenzoic acid(3-PBA) and 3-phenoxybenzaldehyde are the most common intermediates in the degradation pathways of Type Il pyrethroids by bacteria, except the cyfluthrin degradation in Brevibacterium aureum DG-12, the beta-cyfluthrin degradation in Pseudomonas stutzeri S1, and the fenpropathrin degradation in Clostridium sp. ZP3(Chen et al.2013a; Saikia et al.2005;Zhang et al.2011b).
