尼龙66原料的工业开发动向

本文是一篇对尼龙66原料的工业开发动向的文献综述。着重介绍了由苯经由环已烯制备环已醇的工艺条件以及与传统方法的技术经济比较。此外,还介绍了以非苯原料制备己二酸、己二胺的开发情况和市场动向。     

Aberrant expression of nuclear matrix proteins during HMBA-induced differentiation of gastric cancer cells

AIM: To investigate the aberrant expression of nuclear matrix proteins in human gastric cancer cells before and after hexamethylene bisacetamide (HMBA) treatment.METHODS: Proteomics analysis of differential nuclear matrix proteins was performed by two dimensional electrophoresis polyacrylamide gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.The expression levels of three nuclear matrix proteins were further confirmed by Western blotting and their location...     

辛二醇的新合成方法研究

采用新型的还原方法,以硼氢化钾为还原剂,在BF3-Et2O体系中将辛二酸还原成辛二醇.这种方法以价格较低的硼氢化钾为还原剂,降低了生产成本,产率较高,可以实现大规模工业化生产.同时该反应还丰富了羧酸的还原方法,在有机合成中有着一定的意义.     

氰尿酸的合成

用固相法和液相法，将尿素在高温裂解均制得了氰尿酸。本文在讨论液相法合成氰尿酸时报道了了尿素在几种不同溶剂－己二腈，十二烷基苯，硅油ＤＣ－７０５，硅油２１０－５０中裂解的实验结果。
