Living Life as Inquiry

In this paper I explain what I mean by living life as inquiry, showing how I apply notions of inquiry as method to many areas of my professional and personal activities and how research ideas are generated and tested throughout my life space. The paper has twin tracks which reflect the interwoven processes I am describing and advocating. One is more practice based; in it I outline some of my inquiry practices and dilemmas, and give two examples from my work situation. The second track is more focused on theory, highlighting ideas about systemic analysis, influencing change, relational work, and gender. Writing the paper became an example of my topic. I therefore note features of the text which illustrate processes and practices of inquiry.     

二甲基亚砜/N-甲基咪唑体系中木质素和半纤维素改性剥离研究

在二甲基亚砜/N-甲基咪唑(DMSO/NMI)体系中通过乙酰化反应对桑树枝条木质素和半纤维素进行改性剥离,研究了乙酸酐用量、反应时间和溶剂用量对改性剥离效果的影响,并对乙酰化改性剥离机制进行探讨。结果表明,改性剥离较优条件为:乙酰化试剂用量为30 mL,溶剂用量120 mL,反应时间24 h。改性剥离过程显示木质素的改性剥离效果与其乙酰化程度及其衍生物在溶剂中的溶解能力密切相关。析出剥离组分降解较少,有利于后续综合利用;经改性剥离后剩余纤维素的可及度提高。     

强酸性离子交换树脂催化下硼酸三甲酯合成反应的动力学研究

以自制的负载氯化锂强酸性离子交换树脂为催化剂,采用间歇法研究了硼酸和甲醇酯化可逆反应的动力学。对可逆反应动力学方程进行线性化处理,确定了积分法拟合可逆反应动力学参数的方法,并以幂函数形式表达了指前因子与催化剂浓度的关系。测定了不同反应温度和催化剂用量下硼酸三甲酯得率随时间的变化,对动力学数据采用线性拟合,得到硼酸三甲酯非均相催化合成反应动力学方程式为:rA=499.4 C0.38cat exp(-31920/RT)CACB-397.7C0.08 cat exp(-29780/RT)CRCS。
