Isingeniso

I-Benzyl alcohol iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-benzyl alcohol:

 

Ikhwalithi:

- Ukubukeka: Utshwala beBenzyl wuketshezi olungenambala ukuya kokuphuzi.

- Ukunyibilika: Incibilika kancane emanzini futhi incibilika kakhulu kuzincibilikisi zemvelo njenge-ethanol nama-ether.

- Isisindo samangqamuzana esihlobene: Isisindo samangqamuzana esihlobene se-benzyl alcohol singu-122.16.

- Ukuvutha: Utshwala be-Benzyl buyavutha futhi kufanele bugcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu.

 

Sebenzisa:

- Izincibilikisi: Ngenxa yokuncibilika kahle, utshwala be-benzyl buvame ukusetshenziswa njengesixazululi sezinto eziphilayo, ikakhulukazi embonini kapende neyokumboza.

 

Indlela:

- I-Benzyl alcohol ingalungiswa ngezindlela ezimbili ezijwayelekile:

1. Nge-alcoholysis: Utshwala be-Benzyl bungakhiqizwa ukusabela kotshwala be-sodium benzyl ngamanzi.

2. I-Benzaldehyde hydrogenation: i-benzaldehyde i-hydrogenated futhi yehliswa ukuze ithole i-benzyl alcohol.

 

Ulwazi Lokuphepha:

- Utshwala be-Benzyl buyinto ephilayo, futhi kufanele kuqashelwe ukuze buvinjwe ukuthi bungathinti amehlo, isikhumba, futhi bubuphuze.

- Uma uthintana ngengozi, hlambulula ngokushesha indawo ethintekile ngamanzi amaningi futhi ufune usizo lwezokwelapha.

- Ukuhogela umoya we-benzyl alcohol kungabangela isiyezi, ukuphefumula kanzima nokunye ukusabela, ngakho-ke indawo yokusebenza enomoya omuhle kufanele igcinwe.

- Utshwala be-Benzyl yinto evuthayo futhi kufanele igcinwe endaweni epholile, engenamoya, kude namalangabi avulekile kanye namazinga okushisa aphezulu.

- Uma usebenzisa utshwala be-benzyl, landela izinqubo ezifanele zokusebenza zokuphepha kanye nezinyathelo zokuzivikela.
