Abstract: All steps for production of 2,7-dimethyl-octa-2,4,6-trienedial (I) are in presence of an inert, water-immiscible organic solvent, the process involving (A) Lewis acid-catalyzed double enolether condensation of a butenedial-bisacetal with an enol ether; (B) hydrolysis of the acetal group of the product by aqueous acid addition; (C) conversion of the resulting dialdehyde to (I) using an aqueous base; and (D) crystallization of (I) from the mixture. All of the steps (a) - (d) in the following process for production of 2,7-dimethyl-octa-2,4,6-trienedial of formula (I) are effected in presence of an inert, water-immiscible organic solvent : (A) double enolether condensation of a butenedial-bisacetal of formula (II) with an enol ether of formula (III) in presence of a Lewis acid catalyst; (B) hydrolysis of the acetal group of the resulting condensation product of formula (IV) by adding an aqueous acid to form a dialdehyde of formula (V); (C) conversion of (V) to (I) by reaction with an aqueous base; and (D) crystallization of (I) from the mixture.

Abstract: The use of an aqueous polymer dispersion containing at least one hydrogenated styrene/butadiene copolymer as a coating adhesive for adhesive bonding of flat substrates. An Independent claim is included for adhesive bonding of flat substrates involving: (i) coating of a first flat substrate with an aqueous polymer dispersion; (ii) drying of the coating; (iii) heating of the coating to a temperature higher than the coating activation temperature; and (iv) combining a second flat substrate with the first coated substrate to form an adhesive bond at a temperature higher than the coating activation temperature.
