| titleOfInvention | The technology of olefine aldehydr preparing isoprene through liquid phase method |
| abstract | The present invention relates to a kind of method of manufacture isoprene, belongs to chemical products manufacture method technical field.Characterized in that, synthesizing 4,4 dimethyl 1, C 4 fraction containing isobutene, formaldehyde and butyrolactam adverse current is added by the unit of 3 dioxane, is fully reacted in the presence of solid acid catalyst in a kettle., the product rectifying that will be generated, obtain 4,4 dimethyl, 1,3 dioxane.The C 4 fraction containing isobutene and water are added with bottom at the top of reactor respectively in synthesis tert-butyl alcohol unit, fully react in the presence of cationic ion-exchange resin, generate the tert-butyl alcohol, by extraction of the water to the tert-butyl alcohol, improve the yield of the tert-butyl alcohol.4,4 dimethyl, 1,3 dioxane for generating and the tert-butyl alcohol for generating are added in reactor in synthesis isoprene unit, the isoprene purity of generation can reach more than 99.5%.This technique isoprene high income, product impurity are few, and post processing is simple, is the energy and resource-conserving new technology. |
