Siv:
2,5-Dimethyl-3 (2H) furanone yog dav siv nyob rau hauv tshuaj synthesis thiab industrial teb. Nws kuj yog siv los ua cov kuab tshuaj thiab thinner hauv cov xim, txheej, tshuaj ntxuav, thiab cov nplaum, thiab lwm yam.
Txoj kev:
2,5-Dimethyl-3 (2H) furanone tuaj yeem npaj los ntawm alkylation ntawm p-methylphenol. Methylphenol yog reacted nrog isopropyl acetate los tsim 2,5-dimethyl-3 (2H) furanone. Txoj kev sib xyaw no yog catalyzed los ntawm txhuas chloride los yog lwm yam acidic catalysts.
Cov ntaub ntawv kev nyab xeeb:
2,5-Dimethyl-3 (2H) furanone yog ib qho tsis haum tshuaj organic nrog qee yam toxicity. Kev nqus pa thiab kev sib cuag ntawm daim tawv nqaij, qhov muag, thiab lwm yam, yuav tsum zam. Cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab daim npog ntsej muag yuav tsum hnav thaum siv. Ua haujlwm nyob rau hauv qhov chaw uas muaj cua zoo thiab tsis txhob raug cov nplaim taws thiab qhov kub thiab txias. Thaum muaj kev sib cuag, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob. Thaum siv thiab khaws cia, thov ua raws li cov txheej txheem kev nyab xeeb cuam tshuam.
