5-methoxybenzofuran, tshuaj formula C9H10O2, feem ntau abbreviated li Anisole, yog ib tug organic compound. Hauv qab no yog cov lus piav qhia ntawm cov khoom, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv ntawm 5-methoxybenzofuran: Xwm:
5-Methoxybenzofuran yog cov kua tsis muaj xim uas muaj ntxhiab tsw. Nws yog soluble hauv cawv, ether thiab organic hnyav ntawm chav tsev kub, insoluble hauv dej. Nws yog ib qho chaw ruaj khov uas tsis yooj yim cuam tshuam los ntawm lub teeb thiab huab cua.

Siv:
5-methoxybenzofuran muaj ntau yam kev siv hauv kev lag luam tshuaj. Nws yog siv los ua ib qho tseem ceeb reagent thiab nruab nrab hauv cov organic synthesis, thiab tuaj yeem siv los tsim cov tshuaj xws li tshuaj, dyes, fragrances thiab coatings. Nws tseem tuaj yeem siv los ua cov kuab tshuaj hauv kev tsim cov tshuaj pleev ib ce thiab tshuaj tsw qab.

Txoj Kev Npaj:
5-methoxybenzofuran tuaj yeem npaj tau los ntawm methylation ntawm p-cresol (cresol yog ib qho isomer ntawm p-cresol). Tshwj xeeb, cresol tuaj yeem hnov ​​​​mob nrog methanol, thiab cov tshuaj acidic catalyst tau ntxiv los ua rau cov tshuaj tiv thaiv methylation. Cov khoom tsim tau yog purified thiab purified kom muab 5-methoxybenzofuran.

Cov ntaub ntawv kev nyab xeeb:
Thaum tuav 5-methoxybenzofuran, yuav tsum tau ceev faj txog kev nyab xeeb hauv qab no:
1. 5-Methoxybenzofuran yog cov kua ua kua. Kev sib cuag nrog cov hluav taws kub thiab cov hluav taws xob zoo li qub yuav tsum zam kom tsis txhob muaj hluav taws kub los yog tawg.
2. Kev siv yuav tsum hnav cov cuab yeej tiv thaiv tsim nyog, xws li tsom iav kev nyab xeeb, hnab looj tes thiab hnab looj tes, tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
3. nyob rau hauv lub lag luam yuav tsum tau xyuam xim kom tsis txhob nqus ntawm nws cov vapor, yog hais tias ua tsis taus pa nqus tau pa, yuav tsum tam sim ntawd txav mus rau hauv cov huab cua ntshiab, thiab nrhiav kev pab kho mob.
4. Kev kho cov khib nyiab yuav tsum ua raws li cov kev cai thiab cov kev cai kom tsis txhob muaj kuab paug ib puag ncig.

Thov nco ntsoov tias cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb. Thov nyeem cov ntaub ntawv kev nyab xeeb thiab kev khiav hauj lwm cov lus qhia ntawm cov tshuaj muaj feem xyuam ua tib zoo ua ntej siv los yog sim, thiab ua raws li cov txheej txheem kev khiav hauj lwm raug.
