专利摘要生产醋酸的过程包括一氧化碳、甲醇和甲醇衍生物中至少一种,在第一反应器,在反应有效的条件下生产粗醋酸产品;分离粗醋酸产品成至少一种衍生物流,至少一种衍生物流中至少含有残留的一氧化碳;至少部分残留的一氧化碳与甲醇和甲醇衍生物中至少一种通过金属催化剂在第二反应器反应生产额外的醋酸。优先地,第二反应器是均相反应器,并且反应器的一氧化碳分压小于1.05MPa。专利的详细说明引言本发明涉及到从未反应的一氧化碳生产醋酸,如残留物,可能存在于一种或多种粗醋酸产品的衍生物流中。衍生物流是净化和分离粗醋酸产品时得 Patent Abstract The process for producing acetic acid comprises at least one of carbon monoxide, methanol and methanol derivatives, in a first reactor producing a crude acetic acid product under reactionally effective conditions, separating the crude acetic acid product into at least one derivative stream, at least one The derivative stream contains at least residual carbon monoxide; at least a portion of the remaining carbon monoxide reacts with at least one of the methanol and methanol derivatives through the metal catalyst in the second reactor to produce additional acetic acid. Preferentially, the second reactor is a homogeneous reactor, and the partial pressure of carbon monoxide in the reactor is less than 1.05 MPa. Detailed Description of the Patents Introduction The present invention relates to the production of acetic acid from unreacted carbon monoxide, such as residues, which may be present in the derivative stream of one or more crude acetic acid products. Derivatization streams are used to purify and separate crude acetic acid products
