Cyclohexane: Cov Khoom Siv Tshuaj Lom Zem thiab Cov Khoom Siv Tshuaj Rau Kev Tsim Khoom Zoo
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam pleev xim thiab kua mem, cyclohexane siv ua cov kuab tshuaj uas zoo rau ib puag ncig vim nws yaj tau zoo thiab hloov pauv tau yooj yim. Nws tuaj yeem yaj cov khoom siv resin hauv cov txheej xim thiab kua mem sai sai, thiab nws qhov evaporation nruab nrab pab tsim cov txheej sib xws, txo cov kuab tshuaj seem. Cyclohexane tsis muaj tshuaj lom ua rau nws ua raws li cov cai ib puag ncig nruj, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov kuab tshuaj ntsuab.
Hauv kev lag luam tshuaj tsw qab thiab khoom noj, cov ntxhiab tsw zoo li ether ntawm cyclohexane ua rau nws yog ib qho tseem ceeb ntawm cov tshuaj tsw qab. Nws feem ntau siv los sib tov cov roj tseem ceeb, xws li txiv qaub, mint, thiab paj tsw qab, siv dav hauv tshuaj tsw qab, tshuaj pleev ib ce, thiab cov khoom noj tsw qab. Tsis tas li ntawd, cyclohexane tuaj yeem siv ua cov khoom noj ntxiv hauv kev tsim khoom qab zib, dej haus, thiab cov khoom ci, ntxiv cov ntxhiab tsw qab rau cov khoom.
Hauv kev lag luam tshuaj, cyclohexane siv tau ua cov kuab tshuaj thiab cov tshuaj rho tawm. Nws tuaj yeem yaj cov tshuaj organic intermediates, ua kom yooj yim rau cov tshuaj tiv thaiv thiab cov txheej txheem ntxuav tom qab. Tsis tas li ntawd, cyclohexane siv tau rau hauv kev npaj cov tshuaj, xws li tshuaj pleev, tshuaj pleev, thiab tshuaj suppositories, pab cov tshuaj kom tawg thiab nqus tau zoo dua.
Hauv kev lag luam polymer, cyclohexane yog ib qho khoom siv tseem ceeb rau kev tsim nylon (polyamide). Nws raug hloov mus rau cyclohexanol los ntawm catalytic hydrogenation, uas tom qab ntawd hloov mus rau hauv adipic acid thiab caprolactam. Cov tshuaj no yog cov monomers tseem ceeb rau kev tsim nylon 6 thiab nylon 66. Nylon siv dav hauv kev lag luam textiles, automotive, mechanical, thiab electronic vim nws lub zog siab, hnav tsis kam, thiab kub tsis kam.

Hauv kev xaus lus
Nrog kev paub txog ib puag ncig thiab kev nce qib ntawm thev naus laus zis, cov txheej txheem tsim cov cyclohexane tau raug kho kom zoo tas li. Kev tsim cov cyclohexane niaj hnub no siv cov txheej txheem catalytic hydrogenation zoo los txo cov khoom tsim tawm thiab txhim kho kev siv cov peev txheej. Tsis tas li ntawd, kev rov ua dua tshiab thiab kev siv dua ntawm cyclohexane tab tom raug tsim, txo nws cov kev cuam tshuam rau ib puag ncig.
Hauv kev xaus lus, cyclohexane, ua ib qho khoom siv tseem ceeb ntawm cov tshuaj lom neeg organic thiab cov kuab tshuaj, muaj ntau yam kev siv hauv kev tsim khoom lag luam. Nws tsis tsuas yog txhim kho kev ua haujlwm zoo thiab cov khoom zoo xwb tab sis kuj txhawb nqa kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov. Nrog rau kev nce qib ntawm thev naus laus zis tas mus li, kev siv cyclohexane yuav dav dua.
