| titleOfInvention | CONTINUOUS PROCEDURE FOR OBTAINING POLYAMINS FROM AMINONITRILS. |
| abstract | Continuous process for obtaining a polyamide by reacting at least one aminonitrile with water, which covers the following steps: (1) reacting at least one aminonitrile with water at a temperature from 90 to 400 ° C and a pressure of 0.1 to 35 x 106 Pa in a circulation tube, containing a Brönsted acid catalyst, chosen from a catalyst of -zeolite, phyllosilicate or titanium dioxide, formed by 70 to 100% by weight anatase and a 0 to 30% by weight of rutile, in which up to 40% by weight of titanium dioxide can be substituted by tungsten oxide, obtaining a reaction mixture, (2) additional reaction of the reaction mixture at a temperature 150 to 400 ° C and at a pressure that is lower than that in step 1, which can be carried out in the presence of a Brönsted acid catalyst, chosen from a zeolite, phyllosilicate or titanium dioxide catalyst, fo It is assembled by 70 to 100% by weight of anatase and from 0 to 30% by weight of rutile, in which up to 40% by weight of the titanium oxide can be substituted by tungsten oxide, the temperature being selected and the pressure in such a way that a first gas phase and a first liquid phase or first solid phase or a mixture constituted by the first solid phase and the first liquid phase are obtained, and the first gas phase is separated from the first liquid phase or of the first solid phase or of the mixture constituted by first liquid phase and first solid phase, and (3) reaction of the first liquid phase or the first solid phase or the mixture constituted by first liquid phase and first solid phase with a gas phase or liquid, containing water, at a temperature from 150 to 370 ° C and at a pressure of 0.1 to 30 x 106 Pa, if appropriate in a circulation tube, containing a Brönsted acid catalyst chosen from a catalyst of -zeolite, of phyllosilicate or of titanium dioxide, formed by 70 to 100% by weight of anatase and 0 to 30% by weight of rutile, in which up to 40% by weight of the dioxide can be substituted of titanium by tungsten oxide, obtaining a mixture of products. |
