摘要:
Fatty acid derivatives based on epoxidized unsaturated fatty acid esters or triglycerides and reacted with amines such as hydroxy- and/or amino-substituted hydrophilic amines or amino acids and/or with alkanols or with water on the epoxy group and/or the carboxylic ester groups are described. These fatty amides are suitable as surfactants in detergents and cleaners.

Use of mono- and bisoxime esters I where L1 is an oxime moiety of the formula where R1 and R2 are hydrogen or organic radicals and Z1 are alkylene groups, L2 is a second oxime moiety L1 or an organic radical attached via an O or N atom, A is a chemical bond or a linker, and m is 0 or 1, as activators for inorganic peroxy compounds, in particular as cold bleach activators or optical brighteners in detergents, cleaners and bleaches and in disinfectants.
摘要:
N-acylamino carboxylic acids and N-acylamino sulfonic acids and their alkali metal salts from the technical alkali metal salts of amino carboxylic acids and amino sulfonic acids, respectively, with an active content of 50-95% by weight, based on the solids content of the technical alkali metal salts, and from alkyl carboxylates, are prepared by(a) preparing a suspension of the solid anhydrous technical alkali metal salts of the amino carboxylic acids or amino sulfonic acids in the alkyl carboxylates,(b) reacting this suspension by adding more than 30 to 150 mol % of strong bases to give the alkali metal salts of the N-acylamino carboxylic acids or N-acylamino sulfonic acids, and(c) if required preparing therefrom the free N-acylamino carboxylic acids or N-acylamino sulfonic acids in a conventional way by adding acids.
摘要:
Electrostatic toners contain a polymeric binder and, as a charge stabilizer, a compound of the formula ##STR1## where M.sup..sym. is one equivalent of a cation andR is unsubstituted or substituted C.sub.1 -C.sub.18 -alkyl or unsubstituted or substituted phenyl.
摘要:
A process for the preparation of N-allyl compounds of the general formula I ##STR1## in which ##STR2## denotes a nitrogen-containing heterocyclic compound, R.sup.1, R.sup.3, and R.sup.4 independently denote hydrogen or C.sub.1 -C.sub.4 alkyl,R.sup.2 denotes hydrogen or methyl,n is equal to 1, 2, 3, or 4, andX denotes a water-solubilizing anion,wherein a compound of formula II ##STR3## is caused to react, in aqueous medium, with a compound of formula III ##STR4## in which A denotes a radical which can be eliminated as an anion. The compounds produced by the process of the invention are very well suited for use as brighteners in nickel electroplating.
摘要:
Alkanediol bisacetals useful as surface-active substances for industrial purposes, in particular in washing and cleaning agents, have the formula I ##STR1## where R.sup.1 is alkyl or alkenyl of from 6 to 30 carbon atoms,A is 1,2-alkylene of from 2 to 4 carbon atoms,m is from 0 to 50,within each of the pairs R.sup.1, A and m the meanings being identical or different, andn is from 2 to 20.
摘要:
2-Methyl- and 2-hydroxymethyl-serine-N,N-diacetic acid and derivatives thereof of the general formula I ##STR1## in which X denotes hydrogen, alkali metal or ammonium which may or may not be substituted by C.sub.1 -C.sub.4 -hydroxyalkyl groups and Z denotes hydrogen or hydroxyl.The compounds I serve as complexing agents for heavy metal ions or alkaline earth metal ions and as bleach stabilizers or builders in detergents and cleaning formulations.
摘要:
Glycerol aminocarboxylates of the formula ##STR1## where n is from 0 to 10 andR is ##STR2## where L is iminodiacetate, aspartate, glutamate, sarcosinate, glycinate, serinate, hydroxyaspartate, ethanolaminoacetate, diethanolamino, alanate or taurinate andX is hydrogen, an alkali metal, ammonium or substituted ammonium,are prepared by esterifying glycerol or polyglycerols which contain up to 10 glycerol units with maleic anhydride or itaconic anhydride and addition of compound L-H where L is as defined above to the double bonds of the esters, and are used as complexing agents.
摘要:
Pulverulent or water-free liquid detergents each essentially contain surfactants, builders, bleaching agents and effective amounts of compounds of the formula ##STR1## where R.sup.1 is for example C.sub.1 -C.sub.8 -alkyl, substituted or unsubstituted alkyl or C.sub.3 -C.sub.8 -alkenyl, and R.sup.2 and R.sup.3 are each for example H or C.sub.1 -C.sub.16 -alkyl, as bleach activators for peroxides.
摘要:
Long-chain alkylglucosides are purified by extraction with water from reaction mixtures obtainable by reacting monosaccharides and alcohols of 8 or more carbon atoms or by transacetalating short-chain alkylglucosides with alcohols of 8 or more carbon atoms, adjusted to a pH above 6 in either case.
