According to the gas-liquid two-phase jet flow reaction system, the high-efficiency dispersion and mixing of gas-liquid two phases can be realized by breaking bubbles through utilizing the shearing action of jet flow of high-speed liquid; the gas-liquid two-phase jet flow reaction system has the advantages that the flow is simple, the reactor has a simple structure, gas-liquid mixing effect is good, and the like; the gas-liquid two-phase jet flow reaction system is applicable to technology of producing acetic acid through the carbonylation of methanol or a technology of producing acetic anhydride through carbonylation of methyl acetate.

Description

technical field [0001] The invention relates to a gas-liquid two-phase jet reactor and a gas-liquid two-phase jet reaction system comprising the gas-liquid two-phase jet reactor, the gas-liquid two-phase jet reactor and the system are suitable for carbonylation production of acetic acid and vinegar anhydride process. Background technique [0002] Acetic anhydride is an important organic chemical raw material, mainly used in the production of cellulose acetate, photosensitive film, cellulose acetate for textiles, plastics, and is also widely used in medicine, food, pesticides, dyes and other industries. Among them, the production of acetic anhydride mainly includes acetaldehyde oxidation, acetic acid cracking, carbonyl synthesis and so on. Although the process of acetaldehyde oxidation is simple, the process is mature, and the co-production of acetic acid and acetic anhydride can be realized, but the corrosion is serious, the operating conditions are relatively high, the con...
