    摘要： The invention relates to adducts that can be obtained by reacting carbonyl compounds of general formula (I) in which the variables are defined as follows: R1 and R2 are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, whereby R1 and R2 can be bounds to one another while forming a ring. These carbonyl compounds are reacted with cyclic compounds of general formula (II) in which the variables are defined as follows: X is selected among oxygen, sulfur and N—R8; R3 and R8 are the same or different and are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, formyl, CO—C1-C12 alkyl, CO—C3-C12 cycloalkyl, substituted or unsubstituted, CO—C7-C13 aralkyl, CO—C6-C14 aryl, whereby in the event X═N—R8, R3 and R8 can be bound to one another while forming a ring; R4, R5 and R6 are the same or different and are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, whereby two adjacent radicals at time can be bound to one another while forming a ring; n represents a integer ranging from 1 to 4, and; R7 is the same or different and is selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, whereby two adjacent radicals R7 at time can be bound to one another or R6 or R4 can be bound to adjacent R7 while forming a ring.

    摘要： Processes comprising: providing an alkanolic reaction mixture, the alkanolic reaction mixture comprising: at least one alkoxycarbonylaminotriazine; at least one carbonic ester; at least one C1-C13-alkanol, which alkanol may further comprise up to two ether-bound oxygen atoms and may further comprise a substituent selected from the group consisting of C1-C4-alkyls and hydroxyls; and at least one alkali metal alkoxide or alkaline earth metal alkoxide; and subjecting the alkanolic reaction mixture to extraction with a polar extractant such that at least a portion of polar/ionic components present in the reaction mixture are removed, wherein the polar extractant is less than entirely miscible with an organic phase of the reaction mixture, to form an alkanolic phase comprising the at least one alkoxycarbonylaminotriazine and a polar phase comprising the polar extractant and the portion of polar/ionic components; and wherein the extraction is carried out with one or more selected from the group consisting of mixer/settler units, columns, centrifugal field separation extractors, and combinations thereof.
