1-(α-萘乙酰基)-4-芳酰基氨基硫脲及3-(α-萘亚甲基)-4-芳酰基-1,2,4-三唑琳-5-硫酮的合成

许多酰氨基硫脲类衍生物有抗病毒、抗细菌、抗肿瘤等功效,我们曾经通过5-(α-萘)-2H-四唑-2-乙酰肼与芳酰异硫氰酸酯缩合得一系列新的酰氨基硫脲和相关的杂环衍生物,观察到它们在很低的浓度下就有调节小麦芽鞘生长的功能。Kothari等用α-萘乙酰肼与芳基异硫氰酸酯缩和制得一系列1-(α-萘乙酰基)-4-芳基氨基硫脲及     

Synthesis of novel mesoporous silica spheres with starburst pore canal structure

Novel spherical mesoporous silica materials with uniform diameters and starburst mesopore structures were synthesized by a simple one-step procedure with ethanol as the co-solvent in dilute aqueous solution and their formation mechanism was proposed. The arrangement of the pore canal and the diameter of the sphere could be tailored by altering the concentration of ethanol.     

电场作用下苏氨酸的电流特性研究

制备了以液态苏氨酸为沟道材料的四端有机场效应晶体管,观测了其随着栅极电压的不同呈现出源漏两极之间不同的电学特异现象;还观测了苏氨酸在外电场作用下,阻抗随着源漏之间电压频率变化的关系,提出一个极性液体模型解释了其导电机理。

VOCs控制催化剂的研制

以堇青石蜂窝陶瓷体为第一载体、γ-Al2O3为第二载体,制成的含稀土La和过渡金属元素的复合氧化物催化剂,在连续流动的反应体系上评价了催化剂对苯、氰氢酸、乙酸和氯苯等VOCs的氧化反应活性.结果表明: 采用LaCuMn组合制备的催化剂,La的含量在7%～10%左右、Cu的含量在5.5%左右、Mn的含量在7.5%左右时,第二载体γ-Al2O3的负载以采用半胶、pH值4～5、加入某些活性剂、负载量以7%～10%、活化温度为400～500 ℃时制成的催化剂的活性最好,研制的VOCs控制催化剂对各种VOCs均具有很高的催化活性.

Synthesis of Some Allyl-β-Cyclodextrin Derivatives and their Properties as Capillary GC Stationary Phases

Summary Three -Cyclodextrin derivatives (-CDs) were synthesized by substituting the 2,6-OH groups of -CD with allyl groups and the 3-OH groups with three different acyl groups (valeryl, heptanonyl, octanoyl). The chromatographic properties of these -CDs as stationary phases for capillary gas chromatography (CGC) were studied. The test results showed that the three -CDs possessed good coating properties and that the capillary columns coated with them exhibited high column efficiency. These -CDs can separate not only the disubstituted benzene isomers but also some racemic compounds.
