Nhanganyaya
Asidhi (asidhi) isanganiswa yeorganic. Iyi inotevera sumo kune hunhu hwayo, kushandiswa, kugadzira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: Chimiro chakajairika chichena kune-white crystal powder.
-Kunyungudika: Nzvimbo yekunyunguduka kwekomboni kazhinji iri pakati pe100-105 ° C.
-Solubility: Iine solubility yakanaka mune dzimwe polar solvents, zvakadai se ethanol, dimethyl sulfoxide, nezvimwewo. Asi kunyungudika mumvura kwakaderera.
Shandisa:
-asidhi inowanzoshandiswa yepakati mumunda we organic synthesis. Inogona kushandiswa kugadzira zvakasiyana-siyana zvepyrazole kana pyrimidine makomisheni.
-Mushonga uyu unogona zvakare kushandiswa sechinhu chakabikwa mumunda wemishonga.
Kugadzirira nzira:
-Kugadzirira kweasidhi kunogona kuwanikwa kuburikidza ne-multi-step reaction. Imwe nzira yekugadzira yakajairika ndeyekutanga kubva kune pyrazole chinhu uye pakupedzisira kusanganisa icho chinonangwa chigadzirwa kuburikidza nenhevedzano yemakemikari maitiro.
-Iyo nzira yekugadzirira inogona kusiyana zvichienderana nechinangwa chekudzidza, kuwanikwa kwedata, nezvimwewo, uye unogona kutarisa kune akakodzera sainzi kana zvinyorwa zvepatent kuti uwane ruzivo rwakadzama.
Zvekuchengetedza
-iyo asidhi inowanzove yakagadzikana musanganiswa pasi pekushandisa kwakaringana uye kuchengetedza. Nekudaro, sekunge chero kemikari, ichiri kuda kubatwa nekungwarira.
-Inogona kunge inogumbura, saka kutarisirwa kunofanira kutorwa kuti usasangana neganda, maziso kana nzira yekufema.
-Paunenge uchishandisa uye kubata, tevera kwakaringana marabhoritari maitiro uye matanho ekudzivirira ega, uye chengetedza mamiriro ekufema.
