Intshayelelo
I-Valeric anhydride yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-valeric anhydride:
Umgangatho:
- I-anhydride yeValeric lulwelo olungenambala, olucacileyo kunye nevumba elimnandi.
- Idibana namanzi ukuvelisa umxube we-valeric acid kunye ne-valeric anhydride.
Sebenzisa:
- I-anhydride yeValeric isetyenziswa kakhulu njenge-reagent kunye ne-intermediate kwi-organic synthesis.
- Ingasetyenziselwa ukulungiselela iikhompawundi kunye namaqela ahlukeneyo asebenzayo, njenge-ethyl acetate, i-anhydrides, kunye ne-amides.
- I-anhydride ye-Valeric ingasetyenziselwa ukuhlanganiswa kwezibulali zinambuzane kunye neziqholo.
Indlela:
- I-anhydride yeValeric idla ngokuveliswa ngokusabela kwe-valeric acid kunye ne-anhydride (umz. i-acetic anhydride).
- Iimeko zokusabela zinokuthi zenziwe kwiqondo lokushisa eliqhelekileyo okanye zifudumeze phantsi kokhuseleko lwegesi ye-inert.
Ulwazi ngoKhuseleko:
- I-anhydride ye-Valeric iyacaphukisa kwaye iyatshisa, ugweme ukudibanisa nesikhumba kunye namehlo, kwaye uqinisekise ukuba usebenza kwindawo enomoya.
- Ngexesha lokuphatha kunye nokugcinwa, kunqanda ukudibana nee-oxidants okanye i-acids ezomeleleyo kunye neziseko zokuthintela ukusabela okuyingozi.
-Landela iiprothokholi zokuphatha ezikhuselekileyo zeekhemikhali kwaye uzixhobise ngezixhobo ezifanelekileyo zokukhusela ezinjengeeglavu zaselabhu, iiglasi zokhuseleko, njl.
