| titleOfInvention | A continuous process for producing polyamides from aminonitriles and polyamides can be produced in this way |
| abstract | The continuous process for producing polyamide includes the followingnsteps: (1) reaction of at least one aminonitrile with water atnat a temperature of 90 to 400 ° C and a pressure of 0.1 to 35 x 10 6 Pa in the flowna tube that enriches the acidic Brosnsted catalyst,nselected from beta-zeolites, layered silicates, or oxidentitanium dioxide; (2) further reacting the mixture at 150 ton400 ° C under a pressure that is lower than the pressure in step 1, whereinnthe temperature and pressure are chosen so as to obtain the first gas phase ana first liquid phase or a first solid phase or a first mixturensolid and first liquid phases, and the first gaseous phase separates, and (3)nmixing the first liquid and / or first solid phase with the gaseous orna liquid phase containing water at a temperature of 150 to 370 ° C;npressure of 0.1 to 30 x 10 6 Pa, whereby a mixture of products is obtained.nThe subject of the solution is also polyamides in this waynproducible. |
