1, Tshuaj Lub Npe: Potassium Acetate
2, Molecular Formula: C2H3KO2
3, Molecular Luj: 98.14
CAS: 127-08-2 Nr
5, Cim: Nws yog dawb crystalline hmoov. Nws yooj yim deliquescent thiab saj qab ntsev. PH tus nqi ntawm 1mol / L aqueous tov yog 7.0-9.0. Tus txheeb ze ntom ntom (d425) yog 1.570. Melting point yog 292 degree. Nws yog soluble hauv dej (235g / 100mL, 20 degree; 492g / 100mL, 62 degree), ethanol (33g / 100mL) thiab methanol (24.24g / 100mL, 15 degree), tab sis insoluble hauv ether.
6, Siv: Nws yog siv los ua tus neeg sawv cev buffering, neutralizer, preservative thiab xim fixative rau
tiv thaiv tej xim ntawm cov tsiaj thiab nroj tsuag.
7, Ntim: Nws tau ntim nrog lub hnab polyethylene ua txheej txheej sab hauv, thiab lub hnab yas sib xyaw ua ke raws li txheej txheej. Qhov hnyav ntawm txhua lub hnab yog 25kg.
8, Cia thiab Thauj Khoom: Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav thiab qhov cua, khaws cia kom deb ntawm tshav kub thiab ya raws thaum thauj, tshem tawm nrog kev saib xyuas kom tsis txhob muaj kev puas tsuaj. Tsis tas li ntawd, nws yuav tsum tau muab cais tawm ntawm cov tshuaj lom.
