Taw qhia
2,4-Dichloro-5-methylpyridine. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- 2,4-Dichloro-5-methylpyridine yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw muaj zog.
- Nws yog cov kuab tshuaj organic uas dissolves ntau cov organic tebchaw.
- Nws ruaj khov ntawm chav tsev kub, tab sis decomposes yooj yim hauv qhov kub thiab txias, lub teeb, thiab huab cua.
Siv:
- Nws kuj tuaj yeem siv rau hauv cov tshuaj colloidal chemistry thiab electrochemical kev tshawb fawb raws li cationic surfactant.
Txoj kev:
- Kev npaj ntawm 2,4-dichloro-5-methylpyridine tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm methylpyridine nrog phosphorus chloride. Nyob rau hauv ib qho hnyav hnyav, methylpyridine yog reacted nrog phosphorus chloride los ua 2,4-dichloro-5-methylpyridine ntawm qhov tsim nyog kub thiab lub sij hawm tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
- 2,4-Dichloro-5-methylpyridine yog ib qho tshuaj tiv thaiv kab mob uas tuaj yeem ua rau khaus thiab mob ntawm daim tawv nqaij thiab qhov muag.
- Thaum ua qhov kev sim, lawv yuav tsum tau ua nyob rau hauv qhov cua zoo thiab tsis txhob nqus lawv cov vapors lossis hmoov av.
- Yog tias koj nqus tau los yog nkag mus rau ntau qhov sib txuas, nrhiav kev kho mob tam sim ntawd thiab nqa daim ntawv pov thawj Kev Nyab Xeeb Kev Nyab Xeeb.
