| introduction | 2, 3-dimethyl-2-butene is a hydrocarbon organic substance and can be used as an intermediate for pesticides and fragrances. At the same time, it is also used for the production of spices and other agricultural chemicals, especially the use of it instead of new hexene to produce tona musk spices, which has the advantages of low cost and stable product quality. |
| Penggunaan | Tetramethylethylene, namely 2,3-dimethylbutene-2, is an intermediate of pyrethroid fenpropathrin. The intermediate of pesticides and spices is the main raw material for the synthesis of chrysanthemum acid. At the same time, it is also used for the production of spices and other agricultural chemicals, especially the use of it instead of new hexene to produce tona musk spices, which has the advantages of low cost and stable product quality. the raw material of agrochemical cyanuric acid pharmaceutical intermediates, used in the production of new diabetic drugs naglide used in the production of chrysanthemum acid and spices |
| metode produksi | tetramethyl ethylene is obtained by dimerization of propylene. propylene is put into a dimerization kettle, a homogeneous catalyst is added, and catalytic polymerization is carried out under stirring. when the pressure in the kettle drops below 0.01MPa, the reaction of the material is stopped and the oil layer is crude steamed, remove the products of trimer and tetramer, namely C9 ~ C19. Olefins, collect the fraction at 53~75 ℃ as a crude product, which is mainly 2, 3-dimethylbutene-1, and then carry out catalytic isomerization, the reaction temperature is controlled at 85~90 ℃, so that the product is transformed into 2, 3-dimethylbutene-2, namely tetramethylbutene-2, and then carry out rectification to collect the fraction at 71~74 ℃, namely the finished product 2, 3-Dimethylbutene-2, the rest are other by-products C6 olefins. In the dimerization reaction, the one-way conversion rate of propylene is> 90%, the dimerization selectivity is 80%, and the isomerization conversion rate is 79%. |
