Patent ID: 7282066

Claim:
A process for the preparation of an aqueous formulation, comprising heating at least one cyclic compound of the formula I in the presence of at least one compound of the formula II in the presence of water in an amount of 20 to 1000% by volume based on the cyclic compound of formula I, and of an acidic catalyst and, during or after the heating, H—X—R 3 is separated off at least partially, where, in formula I, X is selected from the group consisting of oxygen, sulfur and N—R 6 , R 3 and R 6 are identical or different and are selected from the group consisting of C 1 -C 12 -alkyl, C 3 -C 12 -cycloalkyl, substituted or unsubstituted, C 7 -C 13 -aralkyl, C 6 -C 14 -aryl, substituted or unsubstituted, formyl, CO—C 1 -C 12 -alkyl, CO—C 3 -C 12 -cycloalkyl, substituted or unsubstituted, CO—C 7 -C 13 -aralkyl, CO—C 6 -C 14 -aryl, where, when X is N—R 6 , R 3 and R 6 may be linked to one another with formation of a ring; R 1 , R 2 and R 4 are identical or different and are selected from the group consisting of hydrogen, C 1 -C 12 -alkyl, C 3 -C 12 -cycloalkyl, substituted or unsubstituted, C 7 -C 13 -aralkyl, C 6 -C 14 -aryl, substituted or unsubstituted, it being possible in each case for two neighboring radicals to be linked to one another with formation of a ring; n is an integer from 1 to 4; R 5 are identical or different and are selected from the group consisting of hydrogen, C 1 -C 12 -alkyl, C 3 -C 12 -cycloalkyl, substituted or unsubstituted, C 7 -C 13 -aralkyl, C 6 -C 14 -aryl, substituted or unsubstituted, it being possible for R 5 to be linked to R 4 or in each case two neighboring radicals R 5 to be linked to one another with formation of a ring; R 7 are identical or different and are selected from the group consisting of hydrogen and C 1 -C 4 -alkyl, x is an integer from 1 to 250 and y is selected from the group consisting of zero and 1.
