Nhanganyaya
Iyo organic compound ine formula C6H5ClFN. Imvura isina ruvara ine kunhuhwirira kwakakosha. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: mvura isina ruvara
-Kunhuwa: Kunhuwa kwakakosha
-Kuwanda: 1.36 g/mL
-Kubikira poindi: 137-139 ℃
-Kunyungudika: -4 ℃
-Solubility: Inosanganiswa ne organic solvents, inenge isinganyungudika mumvura.
Shandisa:
Inoshandiswa zvakanyanya mu organic synthesis uye inogona kushandiswa sechinhu chinokonzeresa kana mbishi zvinhu. Iine zvakakosha mashandisirwo mukubatanidzwa kwemishonga yezvipembenene, mishonga yemishonga uye makemikari, uye inowanzoshandiswa mukugadzira mishonga yezvipembenene, dhayi, zvinonyungudutsa, nezvimwe.
Kugadzirira Nzira: Nzira yekugadzirira ye
yakanyanya kuoma. Imwe nzira yekugadzirira ndeyekuwana 5-chloro -2-oxo -3-methyl pyridine ne chloro-propionaldehyde reaction kuburikidza nepyridine seyakagadzirwa, uye kuwana chigadzirwa chekupedzisira kuburikidza ne fluorination reaction.
Zvekuchengetedza
Iyo organic musanganiswa, uye anotevera ekuchengetedza ekuchengetedza anofanirwa kutariswa kana uchiishandisa:
-Toxicity inogona kukonzerwa nekufema, kubata kana kunwa. Kusangana kwakananga neganda, maziso uye mucous membranes kunofanira kudziviswa.
-Pfeka midziyo yekudzivirira yakakodzera semagirovhosi, magirazi uye zvipfeko zvekudzivirira kana uchinge washandiswa.
-Dzivisa kusangana neoxidants, yakasimba acids, mabhesi akasimba uye zvimwe zvinhu kuti udzivise kuita zvisina kuchengeteka.
-Kana kuvuza kuchiitika, matanho akakodzera anofanirwa kutorwa kuti achenese kudonha uye kudzivirira kupinda mudhiraivha system uye nharaunda.
Paunenge uchishandisa iyo koniyuta, tora anoenderana matanho ekuchengetedza zvinoenderana nemamiriro chaiwo uye tarisa kune yekuchengetedza data sheet yekomboni.
