cov khoom piav qhia
Hafnium tetrachloride yog cov khoom dawb grey uas yog ib qho nruab nrab hauv kev sib txuas ntawm cov organic hafnium tebchaw. Nws yog tsuas yog siv nyob rau hauv cov ntaub ntawv science los yog raws li ib tug catalyst nyob rau hauv tshuaj synthesis txheej txheem. Hafnium tetrachloride tuaj yeem cuam tshuam nrog dej, muaj zog hygroscopicity, thiab yog hydrolyzable heev. Cov mis mos molecular yog HfCl4. Cov xim tsis muaj kob, melting point 320 ℃, inorganic compound, tshuaj formula HfCl ₄. Hafnium chloride (IV) tuaj yeem ua tau zoo catalyze qhov ncaj qha esterification thiab condensation cov tshuaj tiv thaiv ntawm carboxylic acids thiab cawv. Nws raug nquahu kom khaws thiab ua haujlwm nyob rau hauv kev tiv thaiv huab cua inert.
