摘要
研究在碱性催化剂存在下,噻唑碘乙烷盐与芳香醛的反应动力学,实验结果表明此类反应符合二级反应。探讨了反应机理,并对反应的速度常数、活化能及活化态的热力学参数(活化自由能、活化焓、活化熵)进行了讨论。
The reactions of thiazole ethiodide with aromatic aldehydes in the presence of pipcridine as catalyst were investigated. It is found that the reaction is of second order. The mechanism was proposed. The rate constants, activation energies of the reactions and the thermodynamic parameters of activation were also calculated and discussed.
