Abstract:
1. A process for separating at least one first material from a mixture comprising the at least one first material and at least one second material, the process comprising: (A) contacting at least one magnetic particle and at least one bifunctional molecule of formula (I) wherein F F wherein Y is independently S, NH, or O, X is N, P, or CH a, b, c, d are each, independently of one another, an integer from 1 to 6, A is at least one structural unit selected from the group consisting of a CRH n is an integer from 1 to 100, x is an integer from 1 to 4, and y is an integer from 1 to 4, or a product of the two, with the mixture comprising the at least one first material and at least one second material, to form an adduct from the at least one magnetic particle, the bifunctional compound of formula (I) and the at least one first material; (B) suspending the adduct obtained in the contacting (A) in a suitable suspension medium, to give a suspended adduct; (C) separating the suspended adduct from the suspending (B) from the suspension by application of a magnetic field, to give a separated adduct; (D) dissociating or further processing the separated adduct separated off in (C), in order to obtain the at least one first material.
