摘 要:研究了微波輻射下30%過(guò)氧化氫氧化環(huán)己烯為環(huán)氧環(huán)己烷中反應時(shí)間、溶劑和催化劑等因素對環(huán)氧環(huán)己烷的選擇性和轉化率的影響。微波輻射50minWO42-/PO43-/cetyl催化環(huán)氧化選擇性為93.1%轉化率為75.2%,與常規條件相比反應時(shí)間明顯縮短且環(huán)氧環(huán)己烷的選擇性和轉化率有所提高。 |
關(guān)鍵詞:環(huán)氧環(huán)己烷; 過(guò)氧化氫; 微波輻射 |

Abstract:Microwave-assisted oxidation of cyclohexene to cyclohexane epoixde with 30% hydrogen peroxide catalyzed by tungsten catalysts without solvent and with ethyl ester as the solvent was studied. We found that in comparison to at generally reflux conditions, the selectivity and conversion of cyclohexane epoxide were slightly raised and the reaction time was obviously reduced by microwave irradiation. |
Key words:cyclohexene hydrogen peroxide microwave irradiation |
