| titleOfInvention | The production method of methylenediphenyl diisocyanates isomer mixture |
| abstract | The present invention includes the method and apparatus that production has methylenediphenyl diisocyanates (MDI) isomer mixture of low 2,2 '-MDI isomer content and high 2,4 '-MDI isomer content.Gained mixture has the reactivity improved, and can be used for food grade application due to reducing the primary aromatic amine formed in the curing process.The method and equipment also include control 4, the content of 4 '-MDI, and described 4,4 '-MDI are the most reactive isomers for allowing it to be used for a variety of applications in mixture. |
