2,5-Dichlorobenzoic acid C화학적 특성, 용도, 생산
화학적 성질
Needle crystals or white crystalline powder. Soluble in ethanol and ether, soluble in hot water. Some volatilize in the vapor.용도
2,5-Dichlorobenzoic acid was used as calibration standard to investigate the gas-phase OH reaction products of biphenyl, monochlorobiphenyl and dichlorophenyl주요 응용
2,5-Dichlorobenzoic acid is used in organic synthesis and pesticide intermediates. It is used to synthesize herbicides chloramben, 2,5-Dichloro-3-nitrobenzoic acid, etc. The pesticide has less phytotoxicity and is not affected by rainy days.제조 방법
2,5-Dichlorobenzoic acid is obtained by reacting p-dichlorobenzene with phosgene to obtain 2,5-dichlorobenzoyl chloride, which is then hydrolyzed.정의
ChEBI: 2,5-dichlorobenzoic acid is a chlorobenzoic acid that is benzoic acid in which the ring hydrogens at positions 2 and 5 are substituted by chloro groups. It is a chlorobenzoic acid and a dichlorobenzene.일반 설명
Needles (from water) or white powder.공기와 물의 반응
Insoluble in water.화재위험
Flash point data for 2,5-Dichlorobenzoic acid are not available; however, 2,5-Dichlorobenzoic acid is probably combustible.Purification Methods
Crystallise the acid from water. [Beilstein 9 IV 1005.] Aromatic acid impurities (to <0.05%) can be removed via the (±)--methylbenzylamine salt as described for 2,4-dichlorobenzoic acid [Ley & Yates Organic Process Research & Development 12 120 2008.]2,5-Dichlorobenzoic acid 준비 용품 및 원자재
