摘要

腺嘌呤作为一种重要的化工原料，已广泛应用于医药、有机合成等领域，目前腺嘌呤采用丙二酸二乙酯与甲酰胺缩合反应合成，环境污染较大。为实现腺嘌呤生产的绿色化，同时探索腺苷中C-N断裂的机理，开展了在高温液态水中无催化腺苷水解反应的研究，考察了高温液态水中初始浓度、搅拌速率、温度对腺苷水解的影响，研究了150～190 ℃下腺苷的水解反应动力学，在假设反应为零级反应的情况下拟合得到了各温度的反应速率常数，并得出活化能为174.1 kJ8226;mol-1。实验结果表明，高温水解中腺苷无催化水解制备腺嘌呤是可行的，而且产率较高。

Abstract

Adenine is an important chemical material widely used in the fields of medicine

organic synthesis and so onPresently

adenine is produced from the condensation of diethyl malonate with formamide

which has serious pollution problemsTo achieve the green production of adenine

noncatalyzed hydrolysis of adenosine in high temperature liquid water was carried outThe effects of initial concentration

agitating speed and temperature on adenosine hydrolysis were studied and the kinetics of adenosine hydrolysis was investigated at temperatures from 150℃ to 190℃Rate constants were evaluated with the zeroth-order reaction assumption and the activation energy was 134.1 kJ·mol-1The experimental results demonstrated that high selective preparation of adenine by non-catalyzed hydrolysis of adenosine in high temperature liquid water was possible.
