Process for producing acetic acid product having low butyl acetate content

A process for producing an acetic acid product having a low butyl acetate content via a carbonylation reaction. The carbonylation reaction is carried out at a temperature of 100 to 300 DEG C, a hydrogen partial pressure of 0.3 to 2 atm, and a rhodium catalyst concentration of 100 to 3000 wppm based on the weight of the reaction medium. The concentration of butyl acetate in the acetic acid product may be controlled by removing acetaldehyde from a stream derived from the reaction medium, and/or by adjusting at least one of reaction temperature, hydrogen partial pressure, and concentration of the metal catalyst. 一种经由羰基化反应来生产具有低乙酸丁酯含量的乙酸产物的方法。该羰基化反应在100-300℃的温度，0.3-2大气压的氢分压和基于反应介质的重量计100-3000wppm的铑催化剂浓度进行。该乙酸产物中乙酸丁酯的浓度可以通过从来源于反应介质的料流中除去乙醛，和/或通过调节反应温度、氢分压和金属催化剂的浓度中的至少一种来控制。
