Abstract

The vapor-phase phosphorylation of cellulose by means of phosphorus trichloride (PCl₃) and phosphorus oxychloride (POCl₃) is presented. It was found that cellulose-O-dichlorophosphines (Cell-O⁶-PCl₂) formed by the reaction of cellulose with PCl₃ and cellulose-O-dichloro-oxyphosphines (Cell-O⁶-P(O)Cl₂) formed by the reaction with P(O)Cl₃ have been hydrolyzed to cellulose-O-hydrogenphosphates (P(III/V)) (Cell-O⁶-P(O)(H)-OH and (Cell-O⁶-P(O)(OH)₂), respectively. Selected chemico-physical properties (SEM-EDS, ³¹P NMR, potentiometric titration) of both types of cellulose phosphates (Cell-O⁶-O-P(O)(H)-OH and Cell-O⁶-O-P(O)(OH)₂) were compared.

纤维素表面与PCl3和P(O)Cl3的磷酸化

摘要介绍了三氯化磷(PCl3)和氯化氧磷(POCl3)气相磷酸化纤维素的反应。发现纤维素与PCl3反应生成的纤维素-O-二氯膦(Cell-O6-PCl2)和与P(O)Cl3反应生成的纤维素-O-二氯膦(Cell-O6-P(O)Cl2)分别被水解为纤维素-O-氢磷酸(P(III/V)) (Cell-O6-P(O)(H)-OH和(Cell-O6-P(O)(OH)2)。比较了两种类型的纤维素磷酸盐(Cell-O6-O-P(O)(H)-OH和Cell-O6-O-P(O)(OH)2)的化学物理性质(SEM-EDS, 31P NMR，电位滴定)。图形抽象

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
