Isingeniso
I-Guiacol iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-guaiacol luff:
Ikhwalithi:
- Ukubukeka: I-Guaiac iwuketshezi olusobala olunephunga elikhethekile.
- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol ne-ether.
Sebenzisa:
- Izibulala-zinambuzane: I-Guiacol kwesinye isikhathi isetshenziswa njengesithako kwizibulala-zinambuzane.
Indlela:
I-Guaiacol ingakhishwa okhunini lwe-guaiac (isitshalo) noma ihlanganiswe nge-methylation ye-cresol ne-catechol. Izindlela zokuhlanganisa zihlanganisa ukusabela kwe-p-cresol nge-chloromethane ecutshungulwa yi-alkali noma i-p-cresol ne-formic acid ngaphansi kwe-acid catalysis nokunye.
Ulwazi Lokuphepha:
- Umhwamuko we-Guaiacol uyacasula futhi ungase ube nomthelela ocasulayo emehlweni, esikhumbeni, nasendleleni yokuphefumula. Gqoka izingubo zamehlo ezivikelayo, amagilavu kanye nemaski uma kunesidingo.
- Kufanele igcinwe kude nomlilo namazinga okushisa aphezulu, futhi igcinwe esitsheni esingangenisi umoya ukuze kugwenywe ukuthintana nama-oxidants.
- Uma usebenzisa i-guaiacol endaweni enomoya omuhle futhi ugweme ukuhogela umhwamuko wayo isikhathi eside.
- Ukuphatha inhlanganisela ngendlela efanele ngokwezinqubo ezifanele zokusebenza kanye nemihlahlandlela yokusingatha ukuphepha. Uma uthinta isikhumba noma usebenzisa, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
