Ethene yog tsim tawm los ntawm kev tawg ntawm cov feem tau los ntawm distillation ntawm nkev nkev thiab roj . (uas tuaj yeem sib txawv heev), thiab lwm yam khoom siv los ntawm kev tawg yog xav tau. Feem coob ntawm ethene yog tsim los ntawm ua kom tawg. Tebchaws Asmeskas tsim txog 25 lab tonnes ntawm ethene ib xyoo.

Ua raws li qhov xav tau, kev siv ethene yog dab tsi?

Ethene yog siv nyob rau hauv zus tau tej cov ethylene glycol (1, 2-ethanediol) uas yog siv raws li ib tug automotive antifreeze neeg sawv cev thiab ua ib tug precursor rau polymers. Siv hauv kev tsim cov polymers xws li polyethylene (Polythene), polyvinyl chloride (PVC), polyester, thiab polystyrene.

Tsis tas li, koj ua ethene li cas? Lub cev qhuav dej ntawm ethanol muab cov ethene Ethanol yog rhuab nrog ntau tshaj ntawm cov concentrated sulfuric acid ntawm qhov kub ntawm 170 ° C. Cov roj uas tsim tawm tau dhau los ntawm cov tshuaj sodium hydroxide kom tshem tawm cov pa roj carbon dioxide thiab sulfur dioxide uas ua los ntawm cov tshuaj tiv thaiv sab. Cov ethene tau sau hla dej.

Tsis tas li, dab tsi yog qhov chaw ntawm ethene?

Ntuj qhov chaw ntawm ethylene muaj xws li ob qho tib si natural gas thiab roj av ; Nws kuj yog ib qho tshuaj hormones tshwm sim hauv cov nroj tsuag, uas nws inhibits kev loj hlob thiab txhawb cov nplooj poob, thiab hauv txiv hmab txiv ntoo , nyob rau hauv uas nws txhawb ripening.

Yuav ua li cas ethane tsim los ntawm ethene?

✔✔ Ethane yog ib qho molecule nrog formula CH3-CH3 thiab ntawm cov ethene CH2 = CH2. Yog li ntawd conversion ntawm cov ethane rau ethene yog qhov pib dehydrogenation cov tshuaj tiv thaiv. ✔✔ Ethane tuaj yeem cuam tshuam nrog Br2 cov pa thaum muaj NBS (N-Bromosuccinamide) uas yuav ua rau cov tshuaj molecules ntawm Bromoethane.
