In the paper the solubilities of anthracene, phenanthrene and carbazole are studied in benzene, toluene, xylene, the heavy solvent oil, clohexane, dmf, pyridine, cyclohexanone and acetone, and qualitative analysis is done by three aspects in the process of the solute dissolved the solvent : ( l ) the molecular struture and the interspace struture ; ( 2 ) reciprocity force of the intermolecule ; ( 3 ) the cohesion energy
本文考察了蒽、菲、咔唑在苯、甲苯、二甲苯、重溶劑油、環己烷、 dmf 、吡啶、環己酮和丙酮等有機溶劑中的溶解度。並從三個方面對溶劑溶解固體定性分析： （ 1 ）分子結構及空間結構， （ 2 ）分子之間相互作用力， （ 3 ）內聚能，得到的結果與實驗得到的數據基本一致。Abstract : 1 - ( 4 - pyridinyl ) - 2 - propanone, which is the key intermediate of synthesizing the milrinone, a cardiotonic agent, was synthesized from 4 - methyl - pyridine by acetylation in dichloromethane and phase transition catalyzing hydrolysis. the overall yield was 73. 1 %
文摘:報道了以4 -甲基吡啶為原料，經酰化和相轉移催化水解反應制備強心藥物米利酮關鍵中間體1 - （ 4 -吡啶基） - 2 -丙酮的新合成方法，總收率達73 . 1 %Six quaternary ammonium tetraphenyl borates salt photobase generators were synthesized with the use of p - methoxy phenacylmethylene or 2 - naphthoymethylene as chromophore, and triethylene diamine, pyridine or 3 - methyl pyridine as tertiary amine
摘要以對甲氧基苯乙酮、萘乙酮生色團為母體、雜環叔胺三亞乙基二胺，吡啶， 3 -甲基吡啶和四苯硼鹽為原料，合成了6種四苯硼季銨鹽光產堿劑。A facile method for the preparation of 10 - arylmethylene anthrone is reported. when anthrone react with aryl aldehyde in the presence of pyridine by using xylene as the solvent, besides 10 - arylmethylene anthrone derivatives we found other oxygenated anthrone which have not been reported. physical methods shows that the oxygenated anthrone is anthraquinone, and the anthraquinone cannot be removed from the condensed products by recrystallization with solvents. an effective method of getting ride of anthraquinone is sublimation by heating
以蒽酮和芳香醛為原料，二甲苯為溶劑，吡啶催化法制取10 -芳香基甲叉基蒽酮.發現其生成物中除含有目標化合物10 -芳香基甲叉基蒽酮外，還含有部分文獻中沒有報道的蒽酮氧化物，經物理方法確定其為蒽醌.該化合物不能用溶劑重結晶的方法將其從縮合產物中除去，有效的分離方法是升華分享友人
