Calcium carbide (CAC2) (cov lus sib dhos: acetylenogen, carbium caletylide, Carbium Dicarbide, Cas Sau Npe Tus Nab {1}}}}, molecular hnyav 64.1)
Tebcav ntawm cov pa roj carbon nrog hlau thiab lwm cov ntsiab lus uas yog electropositive rau cov pa roj carbon yog hu ua carbides. Cov tebchaw no feem ntau yog synthesized los ntawm kev kawm cov hlau lossis lawv cov oxides rau cov txheej txheem kev hloov pauv ntawm cov pa roj carbon.
Ca +2 C → Cac 2
Thaum calcium carbide reacts nrog dej, acetylene yog tsim:
CAC {2 +2 h 2 o → ca (huag) 2 + C 2 h 2
Acetylene (C2h2) yog cov roj tsis muaj xim nrog tus ntxhiab tsw tsaus muag. Nws qhov cub npau npau yog -83. 8 degree thiab nws taw tes khov yog {}}. 8 degree. Cov acitylene, uas tau muab los ntawm calcium carbide, muaj qhov tsis muaj ntxhiab tsw vim yog lub impurities nws muaj. Acetylene undergoes combusionion hauv huab cua, raws li qhov txiaj ntsig ntawm cov khoom kub yog tso tawm. Yog li ntawd, acetylene sib xyaw nrog oxygen yog dav siv rau vuam thiab txiav cov hlau. Acetylene, ib qho yooj yim reastre sib xyaw, hlawv cov pa ntawm huab cua ntawm 3150 degree, tso ib qho tseem ceeb ntawm tshav kub thaum ua ke nrog oxygen. Cov cuab yeej no ua rau nws siv cov khoom siv dav rau vuam thiab txiav cov hlau.
