Isingeniso
I-Amyl valerate. Okulandelayo yisingeniso esinemininingwane ye-amyl valerate:
Ikhwalithi:
- Ukubukeka: I-Amyl valerate iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile.
- Iphunga: Iphunga elimnandi.
- Ukunyibilika: kuncibilika kuzincibilikisi eziphilayo njenge-ethanol, i-ether, i-chloroform ne-benzene, futhi inyibilika kancane kakhulu emanzini.
Sebenzisa:
- Ukusetshenziswa kwezimboni: I-Amyl valerate isetshenziswa kakhulu njengesinyibilikisi futhi ingasetshenziswa kuma-coatings, amapende wokufutha, oyinki kanye nezihlanzi.
Indlela:
Ukulungiswa kwe-amyl valerate ngokuvamile kwenziwa ngokusabela kwe-esterification, futhi izinyathelo ezithile zimi kanje:
I-Valeric acid isabela ngotshwala (n-amyl alcohol) ngaphansi kwesenzo se-catalyst efana ne-sulfuric acid noma i-hydrochloric acid.
Izinga lokushisa lokusabela ngokuvamile liphakathi kuka-70-80°C.
Ngemuva kokuthi ukusabela kuqediwe, i-amyl valerate ikhishwa nge-distillation.
Ulwazi Lokuphepha:
- I-Amyl valerate iwuketshezi oluvuthayo futhi kufanele igcinwe kude nomlilo. Ukunakekela kufanele kuthathwe ukugwema ukuthintana nesikhumba namehlo ngesikhathi sokuphatha.
- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu nezibuko lapho usebenzisa.
- Uma kwenzeka uhogela umoya ngephutha noma ukumuncela ngephutha, funa usizo lwezokwelapha ngokushesha.
