| titleOfInvention | Procedure for regulating the viscosity of a mixture containing at least two components with different viscosity |
| abstract | Method for regulating the viscosity of a mixture (125; 210) containing at least two components with different viscosity, comprising the following steps: (a) determination of the viscosity of the mixture (125; 210) by measurements by ultrasound, (b) standardization of viscosity (132; 222) standardized to standard conditions, (c) comparison of standardized viscosity with a preset target value (134; 224), (d) adjustment of the viscosity of the mixture (125 ; 210) by increasing or decreasing the amount of at least one component of the mixture, in which the mixture (125) containing at least two components with different viscosity, contains monomeric diphenylmethanediisocyanates as well as oligomeric diphenylmethanediisocyanates, in which Ultrasound measurements according to step (a) occur on or in a pipe that conducts the mixture or in a container, in which the mixture (125) composed of several components is ob taken by distillation or crystallization of a crude mixture (112) of diphenylmethanediisocyanates (MDI), in which at least one component is at least partially separated and in which the mixture (112) of crude MDI is the result of a manufacturing process in which the mixture (112) of crude MDI is generated from a mixture of crude diaminodiphenylmethane (MDA) by reaction with phosgene, and for the adjustment of the viscosity in step (d) of the process, the quantity separated from the at least one component by distillation or crystallization and the composition of the mixture (112) of crude MDI by changing the process parameters for the synthesis of MDA is modified, so that the quantity of the at least one Separate component or the amount of the mixture (125) obtained by distillation or crystallization, is constant. |
