Substituting sulfuric acid catalytic hydration technology. The disadvantages of this technology are low conversion rate, low yield of amide products and low by-products, which brings a great burden to the refining. In addition, due to the strong corrosiveness of the catalyst sulfuric acid, the equipment cost is high and the consumption cost is high; The second generation is a binary or ternary framework copper catalytic consumption technology. The disadvantage of this technology is the introduction of metal copper ions that affect polymerization in the final product, thereby reducing the cost of post-processing and refining; the third generation is the catalytic consumption of microbial nitrile hydratase Technology, this technology has mild response conditions, stops under normal temperature and pressure, has the characteristics of high selectivity, high yield and high activity, the conversion rate can reach 100%, the response is intact, and there are no by-products and impurities. The product acrylamide does not contain metal copper ions, and there is no need to stop the ion exchange to enter the copper ions produced during consumption, which simplifies the process flow. In addition, gas chromatography analysis shows that the acrylamide product contains almost no free ions and has high purity. , It is especially suitable for preparing ultra-high molecular polyacrylamide and polyacrylamide required by the food industry. The modified varieties of poly mainly include chlorinated poly, chlorosulfonated poly, cross-linked poly and blended modified varieties.

For the rare earth catalyst system, the Gehler Synthetic Rubber Research Institute used the rare earth element Nd neodymium instead of Ti in the original polymerization catalyst to make a new generation of catalyst, which can increase the content of raw rubber cis-1,4-isoprene rubber and avoid insoluble Things. The crude rubber has large average relative molecules, narrow distribution, short vulcanization processing time, and less catalyst usage, but the cost is higher. This catalyst has been pilot-tested in the late 1980s, and industrial tests have been carried out on the 100-ton/year Bashkiriya synthetic rubber plant. In 1970, rare earth catalyzed isoprene rubber was produced, and a 500-ton/year pilot plant was established in Jilin Chemical Co., Ltd. After long-term operation, it provided dozens of tons of products. The technology was scaled up and industrially tested on the 10,000-ton butadiene rubber plant of Yanshan Petrochemical in 1973. In 1975, it passed the preliminary approval at the ministerial level. In 1987, the basic design of the 13,000-ton/year isoprene rubber plant was completed. The synthetic isoprene rubber technology passed the technical appraisal of the former Ministry of Chemical Industry. In 1992, Shanghai Gaoqiao Petrochemical also proposed a pre-feasibility report for the construction of a 10,000-ton/year isoprene rubber plant. Beijing Rubber Industry Research and Design Institute has also conducted a lot of research on isoprene rubber since the 1960s, and has initially formed a set of application technologies. Although relevant departments have conducted multiple demonstrations on the isoprene rubber project, the production of isoprene rubber is still blank in China. There are two main points of contention: one is the difficulty of collecting C5; the other is whether the price of isoprene rubber can compete with natural rubber. . Facing the huge market opportunities, many foreign companies have begun to expand the production capacity of isoprene rubber and expand the production line of polyisoprene. my country has rare earth isoprene rubber synthesis technology, and the development of isoprene rubber should also be put on the agenda. The by-product in polymerization, commonly known as sub-brand wax, is a PE wax that is purified through a refining process. The product has low viscosity, high melting point, excellent external properties, and low price. However, the quality fluctuates with the change of raw materials and processes. Due to the characteristics of the process, it is inevitable that there will be more low melting point components in the product.
