| titleOfInvention | Process for the joint production of di- and / or polyisocyanates and glycols |
| abstract | The present invention relates to a combined process for the production of diisocyanates and / or polyisocyanates and glycols, the process comprising steps A, B, C and E for producing glycols, and diisocyanates and / or polyisocyanates. Steps A, C, D, E, F and G are included to produce, and the combination of materials is performed by separating the reaction mixture obtained in Step A to form Steps B and C. In step A, the aqueous alkylene oxide reacts with carbon dioxide to form a reaction mixture containing alkylene carbonate, and a portion of the alkylene carbonate-containing reaction mixture obtained in step A is hydrolyzed in step B to produce glycol. The remaining alkylene carbonate-containing stream of the reaction mixture from step A formed is dehydrated in step C and enriched in step D. The amine is synthesized by hydrogenating a group nitro compound or nitrile, and in step E, the dehydrated alkylene carbonate-containing mixture from step C is transesterified using a monohydric alcohol to give the corresponding dialkyl carbonate. Where the glycol is obtained as a combined product, and in step F the dialkyl carbonate-containing reaction mixture obtained in step E is reacted with the amine obtained in step D to give the corresponding monocarbamate, dicarnamethic. And / or a mixture comprising polycarbamates is formed, which is split in step G to give the corresponding diisocyanates and / or polyisocyanates. [Selection] Figure 1 |
