摘要:我们合成了溶血磷脂的各种氨基甲酸酯类似物,即 N-烷基和烯基氨基甲酰基磷脂(acpls),并研究了它们的抗菌特性.所研究的 Acpl 在化学结构的某些方面存在差异:极性头基,与氨基甲酸酯氮相连的脂肪族非极性尾部以及分子骨架,例如 2-O-甲基甘油和 1,3-丙二醇.与溶血卵磷脂和卵磷脂相反,大多数 Acpl 对四膜虫(原生动物)和一系列真菌具有抑制活性.在所研究的一系列 Acpls 中,2-O-甲基-1-O-(n-十四烷基)氨基甲酰基甘油-3-磷酸胆碱(3-C14-A)及其 2-去甲氧基化合物(4-C14-A)的抑制活性最高.与克霉唑相比,这些化合物对吡咯菌有更强的活性,而对人类致病真菌和植物致病真菌的活性则相当或较低.本文讨论了结构与抗菌活性之间的关系.

标题 :Synthesis of linear polyoxazolidinones using uretdiones as diisocyanate component
发明人：QUELL AGGELIKI; THOMAS HANS-JOSEF; ELING BEREND
权利人:BASF SE
摘要:A process for preparing a thermoplastic polymer involves reacting at least components (a) to (b), in the presence of a catalyst composition (c). Component (a) is an isocyanate composition containing at least one uretdione diisocyanate (a-i), and component (b) is an epoxide composition containing at least one diepoxide (b-i). The catalyst composition (c) contains at least one ionic liquid (c-i), preferably selected from 1-ethyl-3-methyl imidazolium bromide, 1-benzyl-3-methyl imidazolium chloride. 1-butyl-1-methylpiperidinium chloride, 1-ethyl-2,3-dimethylimidazolium bromide, 1-(2-hydroxyethyl)-3-methyl imidazolium chloride, butyl-1-methylpiperidinium acetate, or mixtures of two or more thereof. A thermoplastic polymer obtained or obtainable from the process is useful for the preparation of a fibre or a molded article or as a modifier for another thermoplastic material.

标 题 :Method of generating crosslinking sites on the surface of ammonium perchlorate in solid interceptor propellants
发明人：SAYLES DAVID C
权利人:US ARMY
摘要:A method of generating reactive crosslinking sites on the surface of the onium perchlorate particles contained in a Catocene-catalyzed, high-burning rate solid propellant composition by a processing agent which also results in a major improvement in the processibility thereof. The fluid state of the propellant is retained during mixing as a result of interaction between the processing agent prepared prior to incorporating it or when the processing agent is prepared in situ during the propellant mix cycle. There are two alternates available toward improving the processibility of Catocene-catalyzed, high-burning rate propellants. These are: a. The synthesis of a condensation product (processing agent) by the interaction at room temperature of 1,3,5,7,9-pentaazanonane, acrylonitrile, oxiranylmethanol and octadecyl isocyanate in predetermined ratios; or b. Incrementally adding the octadecyl isocyanate to the propellant mix which incorporates the glycidol reaction product of cyanoethyl-substituted tetraethylenepentamine (Tepanol). A major improvement in processing can be effected as a result of the additions of octadecyl isocyanate in 1,2, or 3 increments to the Tepanol-containing mix.
