| abstract | The invention relates to a method for producing aqueous formulations, which is characterized in that at least one cyclic compound of general formula I is heated in the presence of water and an acid catalyst, and H-X-R3 is at least partly isolated during or following the heating process. The variables in formula I are defined as follows: X is selected among oxygen, sulfur, and N-R6; R3 and R6 are identical or different and are selected among C1-C12 alkyl, C3-C12 cycloalkyl, which can be substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, which can be substituted or unsubstituted, formyl, CO-C1-C12 alkyl, CO-C3-C12 cycloalkyl, which can be substituted or unsubstituted, CO-C7-C13 aralkyl, CO-C6-C14 aryl, R3 and R6 optionally being bonded together so as to form a ring in case X represents N-R6; R1, R2, and R4 are identical or different and are selected among hydrogen, C1-C12 alkyl, C3- C12 cycloalkyl, which can be substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, which can be substituted or unsubstituted, two adjacent radicals being optionally bonded together so as to form a ring; n represents an integer between 1 and 4; R5 are identical or different and are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, which can be substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, which can be substituted or unsubstituted, R5 being optionally bonded to R4 or two adjacent radicals R5 being bonded together so as to form a ring. |
