Cov khoom
Cov kua dej tsis muaj xim. Muaj qhov tsw tshwj xeeb. Thaum qhov kub siab tshaj 57 ℃, nws tuaj yeem ua rau miscible nrog anhydrous ethanol, methanol, benzene, ether, acetone thiab lwm yam, tab sis insoluble hauv dej. Flammable heev, nws cov vapor thiab huab cua tuaj yeem tsim kev sib xyaw ua ke, thaum qhib hluav taws, kub kub yooj yim combustion tawg. Kev sib cuag nrog tus neeg sawv cev oxidizing ua rau muaj zog tiv thaiv thiab txawm tias combustion. Nyob rau hauv ib qho hluav taws kub, rhuab ntim yog nyob rau hauv txaus ntshai ntawm tawg. Nws cov vapor hnyav dua li huab cua, tuaj yeem kis mus rau qhov deb ntawm qhov chaw qis, thaum qhov hluav taws kub yuav ntes hluav taws rov qab.
Txheej txheem
Benzene yog hydrogenated los ntawm anhydrous ferric chloride catalyst. Tom qab ntawd ntxuav nrog sodium carbonate tov thiab distilled kom tau ntshiab cyclohexane.
Kev siv tshuab
Siv los npaj cyclohexanol, cyclohexanone, caprolactam, adipic acid thiab nylon 6, thiab lwm yam. Cyclohexan yog siv feem ntau hauv kev tsim cov cyclohexanol thiab cyclohexanone (kwv yees li 90%), nrog rau ntxiv cov adipic acid thiab caprolactam. Lawv yog cov monomers uas tsim cov polyamides. Ib qho me me ntawm kev lag luam, txheej hnyav, resin, roj, roj paraffin, butyl roj hmab thiab lwm yam hnyav hnyav. Tsis tas li ntawd, cyclohexane kuj tseem siv rau hauv kev lag luam tshuaj, rau kev sib txuas ntawm cov tshuaj kho mob. Cyclohexane yog tshwj xeeb tshaj yog haum rau styrene butadiene roj hmab hnyav, nws noj yog feem ntau ntau tshaj 4 npaug ntawm pub. 90% ntawm cyclohexane yog siv nyob rau hauv zus tau tej cov cyclohexanone, uas yog ib tug intermediate khoom nyob rau hauv zus tau tej cov caprolactam thiab adipic acid. Kuj tseem siv los ua hnyav hnyav, chromatographic tsom xam cov khoom siv, photoresist hnyav thiab organic synthesis.
