Yog li kev hloov pauv ntawm ethane rau ethene yog qhov pib dehydrogenation cov tshuaj tiv thaiv

  1. Ethane tuaj yeem cuam tshuam nrog Br2 cov pa thaum muaj NBS (N-Bromosuccinamide) uas yuav ua rau cov tshuaj molecules ntawm Bromoethane.
  2. Qhov saum toj no yielded Bromoethane yuav reacted nrog aqueous alkali hydroxide (KOH / NaOH).

Ua li no, ua li cas koj tau ethane los ntawm ethene?

Los ntawm cov txheej txheem hu ua catalytic hydrogenation, cov ethane tuaj yeem tsim los ntawm ethene . Alkenes teb tau yooj yim nrog hydrogen nyob rau hauv lub xub ntiag ntawm ib tug catalyst xws li finely faib npib tsib xee, platinum los yog palladium.

koj ua ethane li cas? Ntawm qhov anode, acetate yog oxidized rau tsim khoom carbon dioxide thiab methyl radicals, thiab cov reactive methyl radicals ua ke rau tsim ethane : CH3COO → CH3• + CO2 + e. CH3• + •CH3 → C2H.

Yuav ua li cas koj hloov ethene rau ethane sau qhov sib npaug?

Hloov dua siab tshiab ntawm Unsaturated alkene - Ethene (C2H4) rau saturated alkane- Ethane (C2H6) cuam tshuam nrog kev txo qis. Ib alkene muaj ob daim ntawv cog lus uas tau hloov pauv nrog HYDROGEN atoms hauv alkane hauv kev txo qis. Yeej, ntxiv ntawm HYDROGEN lossis tshem tawm OXYGEN yog qhov txo qis.

Peb yuav tau ethene li cas?

Ethene yog tsim los ntawm kev tawg ntawm cov feem uas tau los ntawm distillation ntawm natural gas 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 chav cracking.
