Described herein are aqueous binder formulations including organic compounds including acryloyloxy groups and carboxylic acid hydrazides.

Aqueous binder formulation

A process for producing a thermoformable polymer/fiber composite using a fibrous substrate, an organic di- or polyisocyanate compound and a dispersion polymer.

Method for producing a thermodeformable polymer/fiber composite

A process for producing a thermoformable and/or -embossable fiber/polymer composite using a fibrous lignocellulosic substrate S and a polymer P, which contains

Fiber molding

A process for the preparation of 4-acetals of butene-1,4-dial of the formula ##STR1## where R is an alkyl, alkenyl, cycloalkyl or aralkyl radical of 1 to 12 carbon atoms which may contain alkoxy groups, or the two radicals R together form an alkylene or alkenylene radical of 2 to 10 carbon atoms which may contain alkoxy groups, and R.sup.1 is an alkyl, alkenyl or alkynyl radical of 1 to 12 carbon atoms which may be substituted by cycloaliphatic, aromatic or heterocyclic radicals or by hydroxyl, ether, thioether, acyl, alkylamino, carboxyl or carbalkoxy groups, or is an unsubstituted or substituted aryl radical or an alkoxy, alkylthio or acyloxy group, wherein a glyoxal monoacetal of the formula ##STR2## is reacted with an aldehyde of the formula

Preparation of 4-acetals of butene-1,4-dial and novel acetals of

Motor fuel compositions contain alkoxylation products of oxo oils or their fractions or esters thereof, which are alkoxylated with propene oxide and/or butene oxides and/or not more than minor aomunts of ethene oxide.

Motor fuel compositions containing alkoxylation products

Cyclopentenones of the formula I ##STR1## where each of R.sup.1 to R.sup.4 is independently of the others hydrogen or an organic radical, are prepared by converting a carboxylic ester of the formula IIa, IIb or IIc

Preparation of cyclopentenones

Olefinically unsaturated carboxylic esters having a terminal ester group and of the general formulae Ia and Ib

Preparation of olefinically unsaturated carboxylic esters having a

2-Substituted 4-acyloxy-2-butenals of the general formula I ##STR1## where R.sup.1 is alkyl of 1 to 12 carbon atoms which may be substituted by cycloalphatic, aromatic or heterocyclic radicals, by alkenyl or alkynyl or by hydroxyl, ether, thioether, acetoxy acyl, alkylamino, carboxyl or carbalkoxy, and R.sup.2 is acyloxy, are prepared by reacting a monosubstituted acetaldehyde of the general formula II ##STR2## where R.sup.2 has the abovementioned meaning, with an aldehyde of the general formula III ##STR3## where R.sup.1 has the abovementioned meaning, in the presence of a linear or cyclic secondary amine and of an organic acid at from 20.degree. to 100.degree. C.
