| 대기 기준 | This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Chlorobenzoic acid is produced, as an intermediate or final product, by process units covered under this subpart. /Chlorobenzoic acid/ |
용도
용도
4-Chlorobenzoic acid can be used:As a ligand to synthesize luminescent lanthanide complexes for bio-labeling or fiber communication applications.To prepare organotin(IV) chlorobenzoates exhibiting anticorrosion properties.As a ligand to synthesize di-n-butyl(4-chlorobenzoxy)(4-chlorobenzohydroxamato)tin(IV).
일반 설명
Triclinic crystals or light fluffy white powder.4-Chlorobenzoic acid is a degradation product of indomethacin. It is degraded by Acinetobacter sp. strain ST-1 and causes its dehalogenation to yield 4-hydroxybenzoic acid under both aerobic and anaerobic conditions.
