Isingeniso
I-Butyl butyrate iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-butyrate:
Ikhwalithi:
- Ukubukeka: I-Butyl butyrate iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile olunephunga elimnandi.
- Ukunyibilika: I-butyl butyrate ingancibilika otshwaleni, kuma-ether nezincibilikisi eziphilayo, futhi inyibilike kancane emanzini.
Sebenzisa:
- Izincibilikisi: I-butyl butyrate ingasetshenziswa njenge-solvent ephilayo kuma-coatings, oyinki, ezintweni ezinamathelayo, njll.
- Ukwakhiwa kwamakhemikhali: I-butyl butyrate ingasetshenziswa futhi njengendawo emaphakathi ekuhlanganiseni kwamakhemikhali ukuze kuhlanganiswe ama-ester, ama-ether, ama-etherketones nezinye izinhlanganisela eziphilayo.
Indlela:
I-butyl butyrate ingahlanganiswa ngokusabela kwe-asidi-catalyzed:
Edivayisini yokusabela efanele, i-butyric acid ne-butanol yengezwa emkhunjini wokusabela ngengxenye ethile.
Engeza ama-catalysts (isb. i-sulfuric acid, i-phosphoric acid, njll.).
Shisisa ingxube yokusabela futhi ugcine izinga lokushisa elifanele, ngokuvamile elingu-60-80°C.
Ngemuva kwesikhathi esithile, ukusabela kuphelile, futhi umkhiqizo ungatholwa ngokukhipha izihluthulelo noma ezinye izindlela zokuhlukanisa nezindlela zokuhlanza.
Ulwazi Lokuphepha:
- I-Butyl butyrate iyinto enobuthi obuphansi futhi ngokuvamile ayinabungozi kubantu ngaphansi kwezimo ezijwayelekile zokusetshenziswa.
- Ngesikhathi sokugcina nokuphatha, gwema ukuthintana nama-oxidants, ama-asidi aqinile, ama-alkali aqinile nezinye izinto ukuze ugweme ukusabela okuyingozi.
- Ekukhiqizeni nasekusetshenzisweni kwezimboni, kuyadingeka ukulandela izinqubo zokusebenza eziphephile futhi ugqoke izinto ezifanele zokuzivikela ukuze kuqinisekiswe ukusetshenziswa okuphephile.
