5-Methyl-1 2 4-Oxadiazole-3-Carboxylic Acid (CAS # 19703-92-5) Kev Taw Qhia

5-Methyl-1,2, Acid, tseem hu ua MMT (Methylcyclopropene), yog cov organic compound. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv: Xwm:
- MMT yog cov kua tsis muaj xim uas muaj ntxhiab tsw.
-Nws muaj tsawg solubility thiab yog soluble nyob rau hauv organic solvents xws li ethanol thiab methanol.
- MMT yog ib qho chaw ruaj khov, tab sis nws yuav decompose ntawm qhov kub thiab txias hauv qab hnub ci.

Siv:
- MMT feem ntau yog siv los ua tus tswj kev loj hlob ntawm cov nroj tsuag, thiab nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov ethylene synthesis ntawm cov nroj tsuag, yog li ncua kev loj hlob thiab kev laus ntawm cov nroj tsuag.
-vim nws cov yam ntxwv ntawm ncua kev loj hlob ntawm cov nroj tsuag, MMT muaj ib qho tseem ceeb daim ntawv thov nyob rau hauv cov txheej txheem ntawm cia thiab thauj cov txiv hmab txiv ntoo thiab zaub.

Txoj kev:
Txoj kev npaj tsis tu ncua ntawm-MMT yog tau los ntawm kev ua pa Oxadiazole nrog methanol. Cov kauj ruam tshwj xeeb muaj xws li cua sov cov tshuaj tiv thaiv sib tov, distillation, thiab purification.

Cov ntaub ntawv kev nyab xeeb:
- MMT kuj muaj kev nyab xeeb rau kev siv nyob rau hauv cov xwm txheej dav dav, tab sis cov ntsiab lus hauv qab no tseem yuav tsum tau ua tib zoo saib:
-Tsis txhob nqus pa thiab sib cuag ntawm daim tawv nqaij vim nws cov ntxhiab tsw. Tsim nyog siv cov cuab yeej tiv thaiv tus kheej, xws li hnab looj tes, qhov ncauj qhov ntswg, tsom iav, thiab lwm yam.
- MMT yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab kub kom tiv thaiv nws cov decomposition lossis combustion.
-Thaum tuav lossis khaws cia MMT, cov txheej txheem kev nyab xeeb thiab kev ua haujlwm yuav tsum tau ua raws li kev ruaj ntseg ntawm tus kheej thiab kev tiv thaiv ib puag ncig. Thaum tsim nyog, nws yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated.
