Ib tug loj kev siv ntawm kev sib koom ua ke yog lawv siv raws li catalysts, uas pab hloov tus nqi ntawm cov tshuaj tiv thaiv. Qee qhov nyuaj hlau catalysts, piv txwv li, ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyethylene thiab polypropylene.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov tseem ceeb ntawm kev sib koom ua ke?

Kev sib koom ua ke yog siv los ua catalysts rau ntau cov txheej txheem kev lag luam thiab muaj ntau daim ntawv thov hauv kev tshuaj xyuas zoo / ntau yam tshuaj hauv kev tshuaj xyuas chemistry . Qhov ntawm kev sib koom ua ke muaj qhov tseem ceeb nyob rau hauv biological system, lub kev sib koom ua ke ua lub luag haujlwm tseem ceeb hauv metallurgy thiab tshuaj.

Kuj Paub, kev sib koom ua ke ua haujlwm li cas? Lub hauv paus atoms lossis ion thiab cov atoms pub dawb suav nrog thawj kev sib koom tes kheej kheej. Kev sib koom tes hais txog " koom tes covalent bonds" (dipolar bonds) nruab nrab ntawm ligands thiab lub hauv paus atom hlau complexes yog tsim zoo irreversibly thiab ntau yog khi ua ke los ntawm bonds uas muaj zog heev.

koj txhais li cas los ntawm kev sib koom ua ke?

Txhais ntawm Coordination Compound D . Kho tshiab Lub Xya hli ntuj 11, 2019. A kev sib koom ua ke yog a compound muaj ib lossis ntau dua koom tes bonds, uas yog ib qho kev sib txuas ntawm ib khub ntawm electrons uas ob qho tib si electrons tau pub los ntawm ib qho ntawm cov atoms. Hauv lwm lo lus, nws yog a compound uas muaj a kev sib koom tes complex.

Vim li cas hlau complexes tseem ceeb?

Ib qho ntawm feem ntau tseem ceeb Cov khoom ntawm cov hlau hlau yog lawv lub peev xwm los ua Lewis acids uas tsim complexes nrog ntau yam ntawm Lewis hauv paus. Thib ob, ntau cov khoom lag luam catalysts yog hlau complexes , thiab xws li catalysts tsis tu ncua ua ntau dua tseem ceeb raws li ib txoj hauv kev los tswj reactivity.
