中文拼音 [wánjīzhuǎnyí]
烷基轉移
英文
alkyl transfer-
Phase transfer alkylation
相轉移烷基化反應The formed long and linear chain alkyl benzene changes into benzene methyl and alkene through - scission and monomolecular homolysis, and then benzene methyl shifts to the position of - carbon in the long chain alkyl benzene through h - transfers
已形成的長直鏈烷基苯通過分裂、單分子均裂形成苯甲基、烯烴,苯甲基通過氫轉移到長鏈烷基苯的碳上,烯烴再與碳結合形成帶支鏈的烷基苯。The conclusions are as listed below : compared with absorption of fc16ab in chloroformon, the absorption peak of fcifrab in lb films shifted toward the shorter wavelength region, suggesting that some interaction among molecules due to the close molecular packing such as h - aggregates in the lb films. comparing uv - vis spectra of fc16ab in lb films deposited from cl - subphase with from aqueous subphase, this blue shift phenomenon of absorption demonstrated cl - made the compactness of fc16ab lb films increasing. ft - ir spectra of fc16ab in lb films at different temperature showed that there is a gradual disordering of alkyl chain from 27 ? to 200 ?, but no district phase transition appeared
結論如下:紫外-可見光吸收光譜說明:與fc _ ( 16 ) ab氯仿溶液相比, lb膜的吸收光譜發生了藍移,這歸結于fc _ ( 16 ) ab發生了h -聚集以及抗衡離子可以使fc _ ( 16 ) ab的lb膜排列更緊密;變溫紅外光譜說明,隨著溫度升高, fc _ ( 16 ) ab的lb膜中烷基鏈的有序排布程度減弱,這表明該lb膜熱穩定性減弱,但在減弱的過程中沒有出安徽人學申請碩士學位論文摘要現相轉變。Synthesis of dodecyl glycidyl ether under microwave irradiation and ptc
微波輻射相轉移催化合成十二烷基縮水甘油醚Ethyl vanillin was synthesized by the phase - transfer catalysis cteab and o - ethoxyphenol, which was prepared from pyroeatehol with an overall yield of 55. 2 %, and the factors in the reaction, such as phase - transfer catalysis and temperature, were discussed
摘要以鄰苯二酚為原料,首先合成中間體鄰乙氧基苯酚,然後以十六烷基三乙基溴化銨為相轉移催化劑合成了乙基香蘭素,考察了相轉移催化劑的選擇及反應溫度,最後收率為55 . 2 % 。The oxidation coupling of methane, the partial oxidation of methane to syngas, and the conversion of methane to hydrogen and aromatics are very important academically and economically, for these routes providing ways to produce liquid fuel from natural gas rather than those from petroleum
甲烷的氧化偶聯、部分氧化制合成氣、甲烷制氫和芳烴等的研究工作對于由天然氣生產液體燃料及化工基本原料的石油化工戰略轉移具有非常重要的學術和經濟意義。分享友人
