Isingeniso
I-3,5-Dichloro-4-hydroxybenzoic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-3,5-Dichloro-4-hydroxybenzoic acid iyimpushana yekristalu engenambala engenambala.
- Ukunyibilika: Iyancibilika kwezinye izinyibilikisi zemvelo ezifana notshwala nama-ether, kodwa ayincibiliki kancane emanzini.
Sebenzisa:
Indlela:
- 3,5-Dichloro-4-hydroxybenzoic acid ingatholwa ngokuxutshwa kwe-parahydroxybenzoic acid. Indlela eqondile iwukusabela i-hydroxybenzoic acid ne-thionyl chloride ukuze esikhundleni se-athomu ye-hydrogen eqenjini le-hydroxyl nama-athomu e-chlorine ngaphansi kwezimo ezine-asidi ngokufaka esikhundleni sama-ion e-chloride.
Ulwazi Lokuphepha:
- Imithelela empilweni yomuntu: I-3,5-dichloro-4-hydroxybenzoic acid ayinawo umonakalo osobala empilweni yomuntu ngaphansi kwezimo ezijwayelekile zokusetshenziswa.
- Gwema ukuthintana: Lapho uphatha lesi sithako, gwema ukuthintana okuqondile phakathi kwesikhumba namehlo futhi uqiniseke ukuthi usebenza endaweni enomoya omuhle.
- Izinyathelo zokuvikela isitoreji: Kufanele igcinwe endaweni eyomile, epholile, nengena umoya, kude nomlilo nezinto ezivuthayo.
