摘要
苹果酯是一种新型香料，由乙酰乙酸乙酯和乙二醇反应制得．对苹果酯合成动力学研究结果表明反应对乙酰乙酸乙酯和乙二醇均为一级，反就表现活化能为４３．６７－４４．９８ｋＪ．ｍｏｌ，反应为吸热反应，热效应为２２．２ｋＪ．ｍｏｌ．
Fruetone is a new perfume,made from ethy1 acetoacetate and ethyleneglycol. This paper studies the reaction kinetics of the synthesis of fruetone. It is shown that the reaction is first-order for both ethyl acetoacetate and ethyeneglycpl,with the apparent energy of activation being 43.67～44.98kJ/mol,and it is an endothermic reaction with 22.2kJ/mol of enthalpy.
