Intshayelelo
I-Guiacol yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-guaiacol luff:
Umgangatho:
- Imbonakalo: I-Guaiac lulwelo olucacileyo kunye nevumba elikhethekileyo.
-Ukunyibilika: Inyibilika kwizinyibilikisi ezininzi zezinto eziphilayo, njenge-ethanol kunye ne-ether.
Sebenzisa:
- Amayeza okubulala izitshabalalisi: I-Guiacol ngamanye amaxesha isetyenziswa njengesithako kwizitshabalalisi.
Indlela:
I-Guaiacol inokukhutshwa kwi-guaiac wood (isityalo) okanye ihlanganiswe nge-methylation ye-cresol kunye ne-catechol. Iindlela zokudibanisa ziquka ukusabela kwe-p-cresol kunye nekloromethane ekhutshwe yi-alkali okanye i-p-cresol kunye ne-formic acid phantsi kwe-acid catalysis njalo njalo.
Ulwazi ngoKhuseleko:
- Umphunga weGuiacol uyacaphukisa kwaye unokuba nefuthe elicaphukisayo emehlweni, ulusu kunye nenkqubo yokuphefumla. Nxiba iliso elikhuselayo, iiglavu kunye nemaski ukuba kuyimfuneko.
- Kufuneka igcinwe kude nomlilo kunye namaqondo obushushu aphezulu, kwaye igcinwe kwisikhongozeli esingangeni moya ukuphepha ukudibana nee-oxidants.
- Xa usebenzisa i-guaiacol kwindawo enomoya kwaye ugweme ukuphefumla imiphunga yayo ixesha elide.
- Ukuphatha ikhompawundi ngokuchanekileyo ngokwemigaqo yokusebenza efanelekileyo kunye nezikhokelo zokuphatha ukhuseleko. Kwimeko yokunxibelelana nesikhumba okanye ukusetyenziswa, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
