Nhanganyaya
Valeric anhydride ndeye organic compound. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza yevaleric anhydride:
Hunhu:
- Valeric anhydride imvura isina ruvara, yakajeka uye inonhuhwirira.
- Inopindirana nemvura kuti ibudise musanganiswa wevaleric acid uye valeric anhydride.
Shandisa:
- Valeric anhydride inonyanya kushandiswa se reagent uye yepakati mune organic synthesis.
- Inogona kushandiswa kugadzira makomboni nemapoka akasiyana anoshanda, senge ethyl acetate, anhydrides, uye amides.
- Valeric anhydride inogona zvakare kushandiswa mukugadzirisa kwemishonga yezvipembenene uye inonhuhwirira.
Nzira:
- Valeric anhydride inowanzogadzirwa nekuita kwevaleric acid ine anhydride (eg acetic anhydride).
- Mamiriro ekuita anogona kuitwa pakamuri tembiricha kana kupisa pasi pekuchengetedzwa kweinert gasi.
Zvekuchengetedza
- Valeric anhydride inogumbura uye inoparadza, dzivisa kusangana neganda nemeso, uye ita chokwadi chekushanda munzvimbo inofefetera.
- Panguva yekubata nekuchengetedza, dzivisa kusangana neoxidants kana yakasimba asidhi nemabhesi kudzivirira kuita zvine njodzi.
- Tevedza mapuroteni ekuchengetedza akachengeteka emakemikari uye zvishongedze nemidziyo yekudzivirira yakakodzera senge magurovhosi erabhoritari, magirazi ekuchengetedza, nezvimwe.
