Intshayelelo
I-benzyl utywala yinto ephilayo. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-benzyl alcohol:
Umgangatho:
- Imbonakalo: Utywala beBenzyl lulwelo olungenambala ukuya kumthubi.
- Ukunyibilika: Kunyibilika kancinane emanzini kwaye kunyibilika ngakumbi kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye neetha.
- Ubunzima bemolekyuli obunxulumeneyo: Ubunzima bemolekyuli ye-benzyl yotywala yi-122.16.
- Ukutsha: Utywala beBenzyl bunokutsha kwaye kufuneka bugcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu.
Sebenzisa:
- Izinyibilikisi: Ngenxa yokunyibilika kwayo kakuhle, utywala be-benzyl buhlala busetyenziswa njengenyibilikisi yezinto eziphilayo, ngakumbi kwishishini lepeyinti kunye neengubo.
Indlela:
-Utywala beBenzyl bunokulungiswa ngeendlela ezimbini eziqhelekileyo:
1. Nge-alcohololysis: Utywala be-Benzyl bunokuveliswa ngokusabela kwe-sodium benzyl alcohol kunye namanzi.
2. I-Benzaldehyde hydrogenation: i-benzaldehyde i-hydrogenated kwaye iyancipha ukufumana i-benzyl alcohol.
Ulwazi ngoKhuseleko:
- Utywala be-Benzyl yinto ephilayo, kwaye kufuneka kuthathelwe ingqalelo ukuyithintela ukuba ingadibani namehlo, ulusu, kunye nokuyithatha.
- Kwimeko yoqhagamshelwano ngengozi, ngokukhawuleza uhlambulule indawo echaphazelekayo ngamanzi amaninzi kwaye ufune unyango.
- Ukuphefumla umphunga wotywala we-benzyl kunokubangela isiyezi, ubunzima bokuphefumla kunye nokunye ukusabela, ngoko ke indawo yokusebenza enomoya kufuneka igcinwe.
- Utywala be-Benzyl yinto enokutsha kwaye kufuneka igcinwe kwindawo epholileyo, engenamoya, kude namadangatye avulekileyo kunye namaqondo okushisa aphezulu.
- Xa usebenzisa i-benzyl utywala, landela iinkqubo ezifanelekileyo zokusebenza zokhuseleko kunye nemilinganiselo yokukhusela.
