Abstract: Production of aqueous formulations comprises heating 2-organyl-oxy-, -thio- or -amino-dihydrofuran, dihydropyran, tetrahydrooxepin and tetrahydrooxocin compound(s) in the presence of water and an acid catalyst and (partly) removing the hydroxy, thio or amine compound during or at the end of heating. Production of aqueous formulations comprises heating 2-organyl-oxy-, -thio- or -amino-dihydrofuran, dihydropyran, tetrahydrooxepin and tetrahydrooxocin compound(s) of formula (I) in the presence of water and an acid catalyst and (partly) removing H-X-R3 during or at the end of heating. X = O, S or N-R6; R3, R6 = R, formyl or CO-R or may be combined to a ring if X is N-R6' R = 1-12 C alkyl or an optionally substituted 3-23 C cycloalkyl, 7-13 C aralkyl or 6-14 C aryl group; R1, R2, R4 = H or R or 2 adjacent groups may be combined to a ring; n = 1-4; and R5 = H or R or R4 and R5 or 2 adjacent R5 groups may be combined to a ring. Independent claims are also included for the following: (A) aqueous formulations prepared by this process; and (B) mixtures of dimers, oligomers and polymers of dicarbonyl compound(s) of formula (III).
