Isingeniso
I-Valeric anhydride iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-valeric anhydride:
Ikhwalithi:
- I-Valeric anhydride iwuketshezi olungenambala, olusobala olunephunga elimnandi.
- Isabela emanzini ukukhiqiza ingxube ye-valeric acid ne-valeric anhydride.
Sebenzisa:
- I-anhydride ye-Valeric isetshenziswa kakhulu njenge-reagent futhi iphakathi ku-organic synthesis.
- Ingasetshenziselwa ukulungisa izinhlanganisela namaqembu ahlukene asebenzayo, njenge-ethyl acetate, ama-anhydrides, nama-amide.
- I-anhydride ye-Valeric nayo ingasetshenziswa ekuhlanganiseni izibulala-zinambuzane namakha.
Indlela:
- I-Valeric anhydride ivamise ukukhiqizwa ukusabela kwe-valeric acid nge-anhydride (isb. i-acetic anhydride).
- Izimo zokusabela zingenziwa ekamelweni lokushisa noma ukushisa ngaphansi kokuvikelwa kwegesi ye-inert.
Ulwazi Lokuphepha:
- I-Valeric anhydride iyacasula futhi iyagqwala, gwema ukuthintana nesikhumba namehlo, futhi uqiniseke ukuthi isebenza endaweni enomoya ohlanzekile.
- Ngesikhathi sokuphatha nokugcina, gwema ukuthintana nama-oxidants noma ama-asidi aqinile nezisekelo ukuze ugweme ukusabela okuyingozi.
- Landela izimiso zokuphatha eziphephile zamakhemikhali futhi uzihlomise ngezinto zokuzivikela ezifanele njengamagilavu zelabhu, izibuko zokuphepha, njll.
