The oxidation of aldehydes to isononanoic acid is currently the main production process

General description] Here is a preparation method of a system and method for preparing isononanoic acid, which belongs to the technical field of preparation of chemical raw materials. Isononanoic acid has the following structure: it can be widely used as a raw material for synthetic lubricants, pharmaceutical intermediates, metal soaps and metalworking fluids, and also for alkyd resin modification, which can improve yellowing resistance and impact resistance, and can also be used Production of various isononanoates, which can be used in cosmetics     A preparation method of a system and method for preparing isononanoic acid is introduced here, which belongs to the technical field of preparation of chemical raw materials. Isononanoic acid has the following structure: it can be widely used as a raw material for synthetic lubricants, pharmaceutical intermediates, metal soaps and metalworking fluids, and also for alkyd resin modification, which can improve yellowing resistance and impact resistance, and can also be used Production of various isononanoates, which can be used in the cosmetics field, and its metal salts can be used for different purposes, such as paint driers, vinyl stabilizers, polyvinyl chloride stabilizers and preservatives, and tire adhesion aids. 1603159363479.jpg The oxidation of aldehydes to isononanoic acid is currently the main production process. According to the "Petrochemical Oxidation Reaction Engineering and Technology", the catalysts in the oxidation of aldehydes to carboxylic acids are mostly salts of Co, Mn, and Cu. Such as acetate or naphthenate, its main function is to promote oxidation to produce peracids and promote their rapid decomposition. For example, manganese acetate is used as a catalyst in a device for the peroxidation of ethylene to produce acetic acid, so that the peroxidic acid produced during the peroxidation of ethylene can be decomposed in time to prevent the accumulation, decomposition and explosion of the peroxidic acid. But at the same time, the metal salt can promote the formation of free radicals, accelerate the chain initiation reaction, shorten the induction period of the reaction, and shorten the reaction time significantly. However, with the rapid development of the exothermic reaction, the reaction is difficult to control and the selectivity is reduced. For example, in the process of producing propionic acid by oxidation of propionaldehyde, when manganese acetate, cobalt acetate, iron acetate, and copper acetate are used as catalysts, several catalysts have a greater influence on the selectivity of the product, which is 5%-10% lower than when there is no catalyst; During the reaction process, after multiple material cycles, metal ions such as iron will accumulate in the material flow of the metal reactor and pipeline, thereby promoting the initiation of the reaction, resulting in excessively rapid reaction, rapid increase in heat release rate, and difficult temperature control. It leads to an increase in by-products and a decrease in isononanoic acid selectivity. However, for the oxidation of some aldehydes, the concentration of peroxyacid is not high in the reaction stage, and peroxide will not accumulate in the oxidation reactor, but only because the boiling point of peroxyacid and other components are different and accumulate in the distillation tower. . In this case, adding a catalyst to the oxidation reactor to decompose peroxide is of little significance, but it will result in a greater loss of selectivity. However, if no catalyst is added, it will lead to local enrichment of peroxide in the distillation tower and bring risks, which is an unsolved problem in the prior art. In addition, the peroxide decomposition catalysts used in the prior art are all homogeneous The catalyst has a low concentration, and subsequent separation is difficult, and the distillation tower may have the risk of slagging, blockage and explosion. There are also some patents that use solid acid catalysts to catalyze the decomposition of cumene hydroperoxide into benzene and copper. However, there is no heterogeneous catalyst for peroxide decomposition in the aldehyde oxidation process. In summary, in the prior art for preparing corresponding carboxylic acids by aldehyde oxidation reaction, metal ion catalysts are usually added to the oxidation reactor to accelerate the reaction and the decomposition of peroxides, but the selectivity decreases, the by-products increase, and the product The yield is low and metal ions are not easy to separate. In the prior art, there is no high-efficiency metal-organic framework catalyst to decompose peroxides in the process of aldehyde oxidation to acid, so that the peroxides in the total stream are rapidly decomposed, avoiding the safety problems caused by the accumulation of peroxides in the subsequent rectification process .
