Alkane tuaj yeem npaj los ntawm alkene thiab alkyne los ntawm cov txheej txheem ntawm hydrogenation. Hauv cov txheej txheem no, cov roj dihydrogen ntxiv rau alkynes thiab alkenes hauv cov catalyst tam sim no. Cov catalysts uas tau muab faib ua kom zoo zoo li npib tsib xee, palladium lossis platinum los ua alkanes.
alkenes npaj li cas?
Alkenes feem ntau yog npaj los ntawm β tshem tawm cov tshuaj tiv thaiv, uas ob lub atoms ntawm cov atoms uas nyob ib sab raug tshem tawm, uas ua rau kev tsim ntawm ob daim ntawv cog lus. Kev npaj muaj xws li lub cev qhuav dej ntawm cawv, dehydrohalogenation ntawm alkyl halides, thiab dehalogenation ntawm alkanes.
alkanes ua li cas?
Alkanes tau tsim nyob rau hauv ntau yam microbial tswv los ntawm kev qhia heterologous ntawm cyanobacterial ob-kauj ruam txoj hauv kev. Txoj hauv kev cuam tshuam nrog txo cov roj acyl-ACP rau fatty aldehyde, uas tom qab hloov mus rau n-alkane.
alkanes npaj los ntawm Wurtz cov tshuaj tiv thaiv li cas?
Cov tshuaj tiv thaiv Wurtz, muaj npe tom qab Charles Adolphe Wurtz, yog qhov sib txuas cov tshuaj tiv thaiv hauv cov organic chemistry, organometallic chemistry thiab tsis ntev los no inorganic lub ntsiab-polymers, uas yog ob lub alkyl halides tau hnov mob nrog sodium hlau hauv qhuav ether. tshuaj rau daim ntawv alkane siab dua.
Peb txoj kev npaj ntawm alkanes thiab alkenes yog dab tsi?
Txoj Kev Npaj Ua Ntej ntawm Alkanes
- Decarboxylation.
- Wurtz Reaction.
- Los ntawm Kev Txo Cov AlkylHalides.
- By Hydrogenation ntawm Alkenes((>C=C<): Sabatier thiab Senderen's Method.
- Kolbe's Electrolysis Method.
- By Grignard Reagents.
- Los ntawm Kev Txo Dej Cawv, Aldehydes, Ketones lossis Fatty Acids thiab lawv cov Derivatives.
