Taw qhia
Methylphenyl ether (lub npe hu ua methylphenyl ether) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm p-tolusether:
Zoo:
Methylanisole yog cov kua tsis muaj xim nrog cov ntxhiab tsw ntxhiab tsw. Cov compound no kuj ruaj khov nyob rau hauv cov huab cua thiab tsis flammable yam tsis muaj kev sib cuag nrog muaj zog oxidants.
Siv:
Methylanisole feem ntau yog siv los ua cov kuab tshuaj organic hauv kev lag luam. Nws dissolves ntau cov organic tshuaj thiab feem ntau siv rau hauv cov coatings, tshuaj ntxuav, kua nplaum, xim thiab kua fragrances. Nws kuj yog siv los ua cov tshuaj tiv thaiv nruab nrab lossis hnyav hauv qee cov organic synthesis.
Txoj kev:
Methylanises feem ntau yog npaj los ntawm etherification cov tshuaj tiv thaiv ntawm benzene, thiab cov kauj ruam tshwj xeeb yog los ua benzene thiab methanol nyob rau hauv muaj cov kua qaub catalysts (xws li hydrochloric acid, sulfuric acid) los tsim methylanisole. Hauv cov tshuaj tiv thaiv, cov kua qaub catalyst pab ua kom cov tshuaj tiv thaiv sai thiab tsim cov khoom lag luam siab.
Cov ntaub ntawv kev nyab xeeb:
Tolusoles feem ntau muaj kev nyab xeeb nyob rau hauv cov kev siv ib txwm siv, tab sis cov hauv qab no tseem yuav tsum tau sau tseg:
1. Thaum siv, ib puag ncig zoo-ventilated yuav tsum tau khaws cia kom tsis txhob muaj cov pa paug hauv huab cua.
3. Thaum khaws cia thiab tuav, kev sib cuag nrog cov muaj zog oxidants thiab combustibles yuav tsum raug zam kom tsis txhob muaj hluav taws kub thiab tawg.
4. Lub compound yuav tso tawm cov pa phem thaum nws decomposes, yuav tsum tau muab pov tseg thiab cov kuab tshuaj kom raug.
5. Nyob rau hauv tus txheej txheem ntawm kev siv thiab tuav methyl anisole, nws yog ib qho tsim nyog yuav tsum tau ua raws li nruj me ntsis raws li cov lus qhia txog kev nyab xeeb kev ua haujlwm kom ntseeg tau tias kev nyab xeeb ntawm tib neeg lub cev thiab ib puag ncig.
