Butyric anhydride/CAS：106-31-0

Kagwiritsidwe Ntchito

Butyric anhydride imagwiritsidwa ntchito makamaka ngati acylating reagent mu organic synthesis. Imatha kuchitapo kanthu ndi alcohols, phenols, amines, ndi zina zotero kuti ipange ma esters ofanana, phenyl ethers, amides ndi mankhwala ena. Butyric anhydride ingagwiritsidwenso ntchito ngati zopangira zokutira, utoto ndi mapulasitiki. Butyric anhydride ikhoza kukonzedwa pochitapo kanthu ndi butyric acid ndi acetic anhydride. Nthawi zambiri zimachitika pamene pali asidi komanso kutentha kochepa. Butyric anhydride imakwiyitsa komanso imawononga ndipo ingayambitse kuyabwa m'maso, pakhungu, m'njira yopumira komanso m'mimba. Pa opaleshoni, muyenera kusamala kuti musakhudze khungu ndi maso, ndikuwonetsetsa kuti opaleshoniyo ikuchitika pamene pali mpweya wabwino.

Ndi madzi opanda mtundu komanso owonekera bwino omwe ali ndi fungo loipa. Kuchuluka kwake ndi 0.9668 (20/20℃), kutentha kwake ndi -75℃, ndipo kutentha kwake ndi 198℃. Amasungunuka mu zinthu zosungunulira zachilengedwe monga ether. Amasungunuka kukhala butyric acid akakumana ndi madzi. Amachitapo kanthu ndi ma alcohols kuti apange ma esters. Ndi madzi opanda mtundu, owonekera bwino komanso oyaka moto. Amasungunuka m'madzi ndipo amasungunuka kuti apange butyric acid, ndipo amasungunuka mu ether.

Kulongedza ndi Kutumiza

195 kg/ng'oma kapena malinga ndi zomwe kasitomala akufuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
