Intshayelelo
I-3,5-Dichloro-4-hydroxybenzoic acid yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Ukubonakala: I-3,5-Dichloro-4-hydroxybenzoic acid ayinambala kumgubo omhlophe we-crystalline.
- Ukunyibilika: Inyibilika kwezinye izinyibilikisi eziphilayo ezifana ne-alcohol kunye ne-ethers, kodwa ayinyibiliki kancinci emanzini.
Sebenzisa:
Indlela:
- I-3,5-Dichloro-4-hydroxybenzoic acid inokufumaneka nge-chlorination ye-parahydroxybenzoic acid. Indlela ethile kukusabela i-hydroxybenzoic acid kunye ne-thionyl chloride ukuze ithathe indawo ye-athomu ye-hydrogen kwiqela le-hydroxyl kunye nee-athom ze-chlorine phantsi kweemeko ze-acidic ngokufaka endaweni ye-ion chloride.
Ulwazi ngoKhuseleko:
- Iimpembelelo kwimpilo yabantu: I-3,5-dichloro-4-hydroxybenzoic acid ayinayo ingozi ecacileyo kwimpilo yabantu phantsi kweemeko eziqhelekileyo zokusetyenziswa.
- Gwema ukudibanisa: Xa ubamba le khompawundi, gwema ukudibanisa ngqo phakathi kwesikhumba kunye namehlo kwaye uqinisekise ukuba usebenza kwindawo enomoya.
- Amanyathelo okhuseleko: Kufuneka igcinwe kwindawo eyomileyo, epholileyo, nengena umoya, kude nomlilo nezinto ezinokutsha.
