Low pressure methanol carbonylation synthesis of acetic acid process mainly includes CO gasification and acetic acid production of two parts.Gasification process of sulfur mainly includes gasification, and compressed, the decarburization desulfurization process, acetic acid can be divided into the reaction process and refining production process.Reaction process includes: pretreatment, synthesis, transformation section, etc.Refining process including: evaporation, light, dehydration, stripping section, alkanes, finished products, etc. Key words: acetic acid; Methanol; synthetic 目录 TOC \o 1-3 \h \u 第一章 引言  PAGEREF _Toc26249 1 1.1 醋酸性质和用途  PAGEREF _Toc8344 1 1.1.1 醋酸的物理性质  PAGEREF _Toc1450 1 1.1.2 醋酸的化学性质  PAGEREF _Toc29413 1 1.1.3 醋酸的用途  PAGEREF _Toc4945 3 第二章 醋酸合成方法概述  PAGEREF _Toc353 4 2.1 生产  PAGEREF _Toc29217
