Abstract: Poly-N-acylalkyleneimines corresponding to the following formula ##STR1## are used as an oxidatively crosslinking constituent in paints. In formula (I), R--CO represents the acyl radical of a mono- or polyunsaturated, aliphatic C.sub.16-22 carboxylic acid or a mixture of such radicals, R'--CO represents the acyl radical of a C.sub.1-22 carboxylic acid or a mixture of such radicals and x and y represent the percentages by weight of the particular polymer units, x assuming values of 20 to 100% and preferably 20 to 95% and y assuming values of 80 to 0% and preferably 80 to 5%. The indices m and n independently of one another may assume the value 2 or 3.

Abstract: This invention concerns polyiminoethers of general formula (I) in which A is an aliphatic, aromatic or araliphatic group containing 4 to 40 carbon atoms and n free valencies at various carbon atoms, x may assume values of 0 to 40, n has a value of 2, 3 or 4, Z is either a direct bond or the group CR.sup.5 R.sup.6, the substituents R.sup.1 to R.sup.6 independently of one another are H, alkyl or aryl containing up 8 carbon atoms, the substituent R.sup.7 is hydrogen, methyl or ethyl and Q is a phenylene group, which may be substituted by one or two methyl groups, or the group --CHR--M--, where R is selected from the group consisting of H, alkyl or alkenyl and M is selected from the group consisting of alkylene, alkenylene, arylene and alkarylene, and the parts R and M of the molecule independently of one another contain 0 to 12 carbon atoms and, in addition, may be substituted by a C.sub.1-3 alkoxy group. These compounds are made from polyisocyanates of formula A(NCO).sub.

Abstract: A process for the production of 2-alkyl- or alkenyl-2-oxazolines, in which the alkyl or alkenyl group may be a hydroxy-, dihydroxy- or hydroxy, C.sub.1 -C.sub.2 -alkoxy-substituted hydrocarbon radical containing at least 7 carbon atoms, produces the subject compounds in high yields when C.sub.8 -C.sub.22 fatty acids or esters thereof are reacted with 2-amino-ethanol or ethanolamides of these fatty acids in the presence of titanium or zirconium compounds corresponding to the formula M(OR.sup.2).sub.4 wherein M=Ti or Zr.

Abstract: Novel 2,2-dibromo-3-oxonitriles of Formula I,R--CO--CBr.sub.2 --CN (I)in which R represents in each case a possibly substituted or unsubstituted aliphatic, cycloaliphatic, aromatic or heterocyclic group, with the exception of a phenyl group substituted with 1 to 3 chlorine atoms, can be obtained in that a carboxylic acid ester of Formula IIR--CO--OR' (II)in which R has the significance indicated for Formula I, and in which R' represents a straight chain or branched alkyl group with 1 to 4 carbon atoms, is reacted with acetonitrile in the presence of a strong base, the 3-oxonitrile produced is isolated from the reaction mixture and reacted in a solvent inert with respect to bromine and in the presence of a hydrogen bromide acceptor, possibly under cooling, and the 2,2-dibromo-3-oxonitrile of Formula I obtained is isolated from the reaction mixture.

Abstract: 2-Alkylidene-3,3,5(3,5,5)-trimethylcyclopentanones corresponding to the following general formula ##STR1## in which three of the substituents R.sub.1 to R.sub.4 are CH.sub.3, one of the substituents R.sub.1 to R.sub.4 is H, and R.sub.5 is a saturated or unsaturated, linear branched C.sub.1 -C.sub.7 alkyl radical, and the double bond is in the endo position to the cyclopentanone structure. The compounds of formula (I) are useful as perfumes.

Abstract: A process for the production of 2-benzyl fatty acids and esters thereof corresponding to the following formula ##STR1## comprising reacting 2-fatty alkyl-4,4-dimethyl-2-oxazolines with benzaldehydes corresponding to the formula R.sup.2 --C.sub.6 H.sub.4 --CHO to form 2-(1-benzylidene)-fatty alkyl-4,4-dimethyl-2-oxazolines, catalytically hydrogenating the products of this reaction to the 2-(1-benzyl)-fatty alkyl-4,4-dimethyl oxazolines and converting the products thus formed by acid-catalyzed hydrolysis or solvolysis with an alcohol of the formula R.sup.5 OH into the 2-benzyl fatty acids or esters thereof. Amidosulfonic acid gives particularly high yields as catalyst for the reaction of the 2-fatty alkyl-4,4-dimethyl-2-oxazolines with the benzaldehydes.

Abstract: Detergents on the basis of anionic and nonionic surfactants contain as laundering power-enhancing additives an aliphatic amine compound which is selected such that its pK.sub.b value is at least equal to 14, minus the initial pH value of a 1% aqueous solution of the detergent containing the amine compound. Laundering power-enhancing amine compounds selected according to the rule mentioned are certain ether amines, amidoamines, glucamine derivatives or morpholine derivatives.

Abstract: Use of, and composition containing the reaction products of primary 2-alkyl-1-alkanols containing from 12 to 36 carbon atoms with ethylene oxide and/or propylene oxide as emulsifiers or co-emulsifiers in the emulsion polymerization of ethylenically unsaturated monomers.
