    Abstract: The invention relates to a process for the combinatorial investigation of the hardening of hardenable liquid or viscous formulations (a) in which n hardenable formulations are prepared in parallel in n containers, and (b) the degree of hardening is determined at least once on each of the n formulations by inserting a measurement tip into the formulation with a certain force and measuring the maximum penetration depth achieved as a measure of the degree of hardening of this formulation, and (c) for in each case one composition of the formulations, one or more parameters that are characteristic of the kinetics of hardening are determined from the measurement values for the penetration depth at various times after preparation of the formulations. Steps (a) to (c) are preferably carried out a number of times, and a dependence of the characteristic parameter(s) on the composition of the formulations is determined by analysis of the large number of individual values obtained in this way for the parameter(s) that is (are) characteristic of the kinetics of hardening, enabling the composition of the formulations to be optimized with respect to its hardening behavior.

    Abstract: A process for preparing cocondensates of aspartic acid and amines by heating aspartic acid and amines in the presence of acidic catalysts comprises supplying the feed region of the extruder with particulate aspartic acid and a downstream metering zone with at least one amine and at least one acidic catalyst, condensing the resulting mixture to such an extent by heating that the downstream end of the extruder discharges a precondensate which contains at least 20-95% by weight of the starting aspartic acid in condensed form, and then completing the condensation of the precondensate. The cocondensates are useful as incrustation inhibitors in detergents.
