正丁醛可在羰基钴催化下由丙烯氢甲酰化获得：CH3CH=CH2+CO+H2CH3CH2CH2CHO（正丁醛）副反应：CH3CH=CH2+CO+H2（CH3）2CHCHO（异丁醛），温度对丙烯氢甲酰化产物_刷题宝

题干

正丁醛可在羰基钴催化下由丙烯氢甲酰化获得：CH₃CH=CH₂+CO+H₂

CH₃CH₂CH₂CHO（正丁醛）副反应：CH₃CH=CH₂+CO+H₂

（CH₃）₂CHCHO（异丁醛），温度对丙烯氢甲酰化产物中正/异醛比的影响如下图：

下列说法正确的是（）

A：丙烯氢甲酰化反应是放热反应

B：丙烯与CO₄H₂混合催化时，可能有丙烷及正丁醇等副产物生成

C：相同物质的量的丙烯合成正丁醛时，温度越高，所获得的正丁醛的产量一定越大

D：温度不变时，只改变体系的压强，对产率没有影响
