Mawu Oyamba
Valeric anhydride ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha valeric anhydride:
Ubwino:
- Valeric anhydride ndi madzi opanda mtundu, owoneka bwino komanso onunkhira.
- Imachita ndi madzi kupanga chisakanizo cha valeric acid ndi valeric anhydride.
Gwiritsani ntchito:
- Valeric anhydride amagwiritsidwa ntchito makamaka ngati reagent komanso wapakatikati mu kaphatikizidwe ka organic.
- Itha kugwiritsidwa ntchito popanga mankhwala okhala ndi magulu osiyanasiyana ogwira ntchito, monga ethyl acetate, anhydrides, ndi ma amides.
- Valeric anhydride itha kugwiritsidwanso ntchito popanga mankhwala ophera tizilombo ndi zonunkhira.
Njira:
- Valeric anhydride nthawi zambiri amapangidwa ndi zomwe valeric acid ndi anhydride (mwachitsanzo acetic anhydride).
- Zomwe zimachitikira zimatha kuchitika kutentha kwachipinda kapena kutenthedwa motetezedwa ndi mpweya wa inert.
Zambiri Zachitetezo:
- Valeric anhydride imakwiyitsa komanso ikuwononga, pewani kukhudzana ndi khungu ndi maso, ndipo onetsetsani kuti mukugwira ntchito pamalo abwino mpweya wabwino.
- Pogwira ndi kusunga, pewani kukhudzana ndi ma okosijeni kapena ma asidi amphamvu ndi maziko kuti mupewe zoopsa.
- Tsatirani ma protocol otetezedwa amankhwala ndikudzikonzekeretsa ndi zida zoyenera zodzitetezera monga magolovesi a labu, magalasi otetezera, ndi zina.
