Kev Purity N-Hephane yog cov organic compound nrog cov tshuaj noj tshuaj c7h16. Nws yog ib qho tsis muaj kob, pob tshab, cov kua dawb. Nws yog insoluble hauv dej, soluble hauv ethanol thiab carbon tetrachloride, thiab ua kom tiav hauv ethero, acetone, thiab benzene. Nws yog feem ntau yog siv los ua tus qauv thiab siv zog rau kev txiav txim siab oxiation, thiab tseem siv tau rau kev npaj cov organic synthesis thiab sim tshuaj reagents.
1. Siv ua ib qho kev ntsuas hluav taws xob, roj av tshuab khob qhov rooj, chromatographic tsom ntaub siv, thiab cov kuab tshuaj.
2. Nws tuaj yeem siv los ua cov tshuaj tiv thaiv cov roj thiab cov roj cog thiab cov rog, thiab cov roj hmab qhuav-qhuav. Khawb rau cov roj hmab kev lag luam. Nws kuj tseem siv los ua kev ntxuav kom huv hauv cov txheej txheem, cov kua roj vanish, cov inks qhuav, thiab kev lag luam luam ntawv.
3. Siv los ua tus qauv thiab siv zog rau kev txiav txim siab octane, thiab rau kev npaj ntawm cov khoom siv organic thiab kev sim tshuaj reagents
