【摘要】 醚化反应中醚的热化学性质是工艺设计及工程开发的基础。采用基团贡献法对甲基叔烷基醚（Ｃ４～Ｃ７）的标准生成热、绝对熵及等压热容等热化学性质进行了估算，同时估算了部分醚化反应的反应热。结果表明，其精确度完全可满足工程开发的需要。更多还原

【Abstract】 The standard heats of formation,the standard entropies,and the heat capacition of(C 4～C 7)methyl tert-alkyl ethers are estimated using additivity rules The heats of some reactions for etherification are also calculated The results indicates that the accuracy of the method is satisfactory for meeting the need of the engineering developing of etherification更多还原
