Intshayelelo
I-3,4-Xylenol, eyaziwa ngokuba yi-m-xylenol, i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-3,4-xylenol:
Umgangatho:
- I-3,4-Xylenol lulwelo olungenambala kunye nencasa ekhethekileyo enevumba elimnandi.
- Inepropati yokunyibilika emanzini kunye nezinyibilikisi ezininzi eziphilayo.
- Ibonakala njengesakhiwo sedimer esinqamlezileyo kwiqondo lobushushu begumbi.
Sebenzisa:
- Isetyenziswa njenge-antibacterial and antiseptic ingredient kwi-fungicides kunye ne-preservatives.
- Isetyenziswa njenge catalyst kwezinye iikhemikhali reactions synthesis.
Indlela:
- I-3,4-Xylenol inokulungiswa ngokuphendula kwe-condensation ye-phenol kunye ne-formaldehyde phantsi kweemeko ze-acidic.
- Ekuphenduleni, i-phenol kunye ne-formaldehyde i-catalyzed yi-catalyst acidic ukuvelisa i-3,4-xylenol.
Ulwazi ngoKhuseleko:
- I-3,4-Xylenol inetyhefu ephantsi, kodwa kusabalulekile ukuyisebenzisa ngokukhuselekileyo.
- Imiphunga okanye izitshizi zinokucaphukisa kwaye zenze umhlwa emehlweni kunye nolusu.
- Xa usebenza, sebenzisa izixhobo ezifanelekileyo zokuzikhusela, ezinjengeeglavu zekhemikhali kunye nezibuko.
- Xa ugcina kwaye uphatha i-3,4-xylenol, kubalulekile ukulawula ngokufanelekileyo inkunkuma ukuphepha ukungcoliseka kwendalo.
