Kev npaj ntawm

Txoj kev: 1. Natural gas chlorination method natural gas reacts with chlorine gas, absorbs hydrochloric acid byproduct of hydrogen chloride los ntawm dej, tshem tawm cov seem seem hydrogen chloride nrog lye, thiab ces dries, compresses, condenses thiab distills cov khoom tiav. Ntawm lawv, chlorine 100 feem pua 4000, natural gas (standard condition), methane 97 feem pua 1000m/t, kua alkali 100 feem pua 274.

Chloromethane thiab chlorine gas react nyob rau hauv 4000kW lub teeb los tsim dichloromethane, uas yog tiav los ntawm alkali ntxuav, ju shrinkage, condensation, ziab thiab distillation. Cov khoom tseem ceeb ntawm trichloromethane. Chloromethane Ntau dua lossis sib npaug li 98 feem pua 746, kua chlorine Ntau dua lossis sib npaug li 99.5 feem pua 854, caustic soda 30 feem pua 221.

Industrial synthesis feem ntau yog ua los ntawm chlorination ntawm methane. chlorination ntawm methane yields ib tug sib tov ntawm plaub chloromethane tebchaw, uas yuav muab tau yooj yim sib cais thiab purified los ntawm cov txheej txheem fractionation zoo tib yam vim hais tias ntawm qhov deb loj ntawm cov ntsiab lus boiling.
