- Tshuaj lom neeg cov tshuaj tiv thaiv: nws tuaj yeem siv ua qhov nruab nrab hauv kev sib txuas ntawm lwm cov ocegic ntawm lwm cov ocegic teb, xws li heterocyclic tebchaw .
Cov Ntaub Ntawv Kev Nyab Xeeb:
- paraxylene yog volatile organic sib txuas thiab yog lom .}}}}} allation ntawm roj .
- Thaum siv, cua muaj kev nyab xeeb zoo yuav tsum tau coj mus rau kom tsis txhob muaj nws txoj kev xav ntau tshaj qhov kev nyab xeeb txwv.
- Saib xyuas yuav tsum tau them rau hluav taws thiab tawg kev phom sij thiab zam rau kev sib cuag oxidising oxiding thiab muaj zog acids.
- yog tias qhov tsis muaj kev sib tsoo, lub tole yuav tsum tau tshem tawm sai sai thiab tsim nyog khib txoj kev pov tseg yuav tsum tau saws .
- Muab cia kom deb ntawm cov cua sov, Irchit cov chaw thiab ua si ncaj qha .
Ua ntej siv thiab tuav cov neeg paraxylene, nyeem nws cov ntaub ntawv pov thawj kev nyab xeeb kom zoo thiab ua raws li cov txheej txheem kev ua haujlwm muaj feem xyuam thiab kev nyab xeeb {}}
