| titleOfInvention | Apparatus for the liquid-phase synthesis of isoprene from isobutylene and formaldehyde |
| abstract | The invention relates to an apparatus for the liquid-phase synthesis of isoprene from isobutylene and formaldehyde, including a unit for synthesizing products of isoprene precursors, namely 1,3-dioxanes, trimethyl carbinol derived from an isobutylene-containing fraction, and trimethyl carbinol derived from recycled concentrated isobutylene isolated both from an isoprene synthesis unit and a synthesis product separation and isoprene monomer isolation unit. The apparatus is characterized by a 1,3-dioxane synthesis unit that includes the separation of by-products into light, medium, and heavy fractions, from which the light fraction of the by-products is supplied for homogeneous decomposition to the isoprene synthesis unit and/or to a by-product decomposition unit for combined decomposition with by-products obtained during the separation of synthesis products and isolation of isoprene isomers, and the medium fraction of by-products is assigned for sale and/or is mixed with the light fraction of by-products and sent to the by-product decomposition unit. Moreover, the unreacted isobutylene from a unit for the synthesis of trimethyl carbinol derived from recycled concentrated isobutylene is fed into a unit for the synthesis of trimethyl carbinol from the isobutylene-containing fraction and is mixed with said fraction beforehand. The invention reduces the specific consumption of feedstock due to the gain of additional amounts of isoprene from the decomposition of by-products, and also reduces the production cost of the target product due to the sale of the medium fraction of by-products and reduced expenditures on heat energy because there is no need for steam letdown, and increases the productivity of the apparatus. |
