新工科项目“地方(行业)高校化学类专业应对产业变化的升级改造研究与实践”的实施

This "emerging engineering education (3E)" project "Upgrade and Practice of Chemistry-related Majors of Local and/or Specialized University Responding to the Industry Changes" was supported by the Ministry of Education. To aim at the issue of how to upgrade the chemistry-related majors of a local and/or specialized university responding to industry changes, an investigation on local regional economy and industry changes was carried out, the capability requirements of 3E for talents were analyzed, and the training objectives, graduation requirements as well as the new teaching models were also studied for the major to meet the future requirements. The practical experience for 3E construction of chemistry-related majors by selected universities was suggested.     

新鄂西香茶菜素的X射线结构分析

新鄂西香茶菜素为首次从抗癌中草药鄂西香茶菜[Rabdosia henryi (Hemsl) Hara]的叶子中分离得到的二萜化合物。前人曾从毛叶香茶菜[R. japonica (Burm. f)Hara]中分离出该化合物并依据光谱数据推测其结构(右图)。但其结晶学研究尚未见报道。为研究其立体结构及分子在晶体中的排布方式,我们对该化合物的晶体进行了X射线结构分析。     

反相高效液相色谱法测定3种中成药中的葛根素

 建立了测定小儿清感灵片、步长新脑心通胶囊和感冒清热颗粒 3种中成药中葛根素含量的反相高效液相色谱方法。采用APEXODS色谱柱 ,以醋酸铵缓冲液 (10 0mmol/L ,pH 5 0 ) 甲醇 (体积比为 75∶2 5 )的混合溶液为流动相 ,检测波长为 2 5 0nm ,流速为 0 8mL/min。葛根素在 2mg/L～ 2 0mg/L时其色谱峰面积与质量浓度的线性关系良好 (r =0 9999) ;上述 3种中成药中的葛根素含量分别为 3 48mg/g ,1 0 8mg/ g及 1 5 2mg/ g(蔗糖型 ) ;其加样回收率分别为 99 0 % ,93 4%和 97 5 %。该法简便、快速、专属性强 ,可以作为多种中药制剂中葛根素含量的测定方法。     

“能源化学”本科专业建设建议

"Energy chemistry" was approved as one of the chemistry majors for undergraduate by the Ministry of Education in 2015. Based on the ideas and ways of emerging engineering education, this paper hereby proposed some of constructive suggestions on the training objectives, graduation requirements, curriculum system, teaching contents, teaching staff and conditions for development of "energy chemistry" major.     

面向化妆品产业升级的江南大学应用化学专业建设思考与实践

Based on the development prospect of cosmetics industry, the advantage of light industry characteristic and the foundation of applied chemistry in Jiangnan University, a systematic upgrading of applied chemistry was carried out through "emerging engineering education (3E)" project "upgrade and practice of chemistry-related majors of local and/or trade university responding to the social developments" supported by the Ministry of Education. On the basis of investigation and analysis, the orientation and training goal of applied chemistry were updated first, and then the curriculum system was determined and the curriculum construction is strengthened, so as to achieve more distinctive characteristics, more solid foundation and more comprehensive quality. In view of the new requirements of the 3E for talent training, some practices have been formed in the aspects of multi-disciplinary integration, multi-angle coordination and close integration to industry. Contributing the development of cosmetics industry and seizing the commanding point of science and technology from the perspective of talent training, will play a unique role in human social progress.     

3，9－二羟乙基－3＇，9＇－二苯甲基－1，5，7，11－四氧杂螺环［5，5］十一烷的合成和聚合反应

从两二酸二乙酯、氯乙酸乙酯和氯苄出发，经ＬｉＡｌＨ４还原，合成新的二元醇，进而合成新的螺环化合物：３，９－二羟乙基－３＇，９＇－二苯甲基－１，５，７，１１－四氧杂螺［５，５］十一烷．该化合物的结构由它的氢和碳－１３核磁共振谱、红外光谱和元素分析得到证明．该单体在三氟化硼乙醚络合物的作用下进行开环聚合反应．由于环上四个取代基的稳定作用，聚合物的收率比较低（产率１０％左右）．通过对聚合物的结构分析，提出了这一单体的阳离子开环聚合反应机理．对随聚合温度升高，聚合物中酯基／苯基的克分子比降低，以及本体聚合时得到交联聚合物等一系列现象作了探讨．     

美国开发出食品保质检测新装置

不久前，美国开发出一种全新的食品保质检测装置，该装置由传感器与传感器与扫描器构成。据悉，传感器的主要材料是铅，包装食品时，将它置于食品匣内。检测时，扫描器对食品发射的无线电波信号会使食品产生振动，同时发出乐谱波。乐谱波先反射到食品盒壁上，后传导给传感器，通过标准数据库标定振动程度、振动传导时间及乐谱波的传导速度，瞬间即可确定所检测食品发生变质的时间。
