摘要:
The invention relates to compositions and methods for smoothing textile fibers which compositions are characterized in that they contain as lubricants an aliphatic polyether corresponding to the following general formula:R.sup.1 --X--O--R.sup.2in which R.sup.1 and R.sup.2 are linear and/or branched, saturated and/or saturated, OH-containing or OH-free C.sub.6 -C.sub.24 alkyl radicals of natural and/or synthetic origin and X is a homopolymer or copolymer containing one or more C.sub.2 -C.sub.6 alkylene oxides having a degree of polymerization of 1 to 25, either alone or in admixture with other smoothing agents.The other smoothing agents include paraffins, polyethylenes, fatty acid ethers, silicones or polyalkylene glycols. The compositions may be applied to textile fiber in the form of solutions, emulsions or aqueous dispersions.
摘要:
The resistance to yellowing of fabric treatment agents obtainable by reaction of aliphatic C.sub.8 -C.sub.22 mono-carboxylic acids or amide-forming derivatives thereof with polyamines and subsequent neutralization of unreacted amino groups is vastly improved by carrying out neutralization with phosphorous acid.
摘要:
Quaternized esters having fabric-softening and hydrophilicizing properties are obtained by reaction of unsaturated fatty acids containing at least 40 mol-% transconfigured double bonds or esters thereof with alkanolamines and subsequent quaternization of the reaction products with alkylating agents.
摘要:
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.

The invention relates to alkoxylated compounds prepared by reaction of epoxidized C.sub.10-22 carboxylic acid derivatives with C.sub.2-4 alkylene oxides in the presence of alkoxylation catalysts and mono- and/or polyhydric alcohols.
摘要:
A process for the preparation of polyether polyamines comprising the steps ofA) reacting a polyol with an epihalohydrin in the presence of a catalyst;B) adding an at least equimolar quantity of an aqueous alkali metal hydroxide, based on the weight of catalyst, to the reaction mixture formed in step A);C) distilling volatile constituents from the reaction mixture from step B) at a temperature below about 150.degree. C. and under a pressure below about 1.33.times.10.sup.4 Pa.;D) filtering the reaction mixture remaining after step C) at a temperature in the range of from about 80.degree. C. to about 100.degree. C. to remove insoluble components thereof from the bishalohydrin reaction product; andE) reacting the bishalohydrin reaction product with ammonia and/or an amine in the presence of an alkaline catalyst to form a polyether polyamine.
摘要:
Quaternary ammonium phosphates produced by reacting a dicarboxylic acid with an alkoxylated tertiary amine to prepare an amino-functional polyester, mixing the polyester in the presence of water with a phosphoric acid ester, and reacting the mixture with an alkylene oxide at elevated pressure and temperature. The quaternary ammonium phosphates are useful as anti-static agents for textile fiber materials.
摘要:
In the production of monoalkylphosphoric acid esters, at least one fatty alcohol or mixtures of fatty alcohols containing from 8 to 18 carbon atoms and preferably from 12 to 14 carbon atoms in a straight chain is/are reacted with a 0.2 to 2 molar excess of polyphosphoric acid at a temperature of 60.degree. to 130.degree. C.; following an after-reaction time of 120 to 300 minutes at a temperature of 95.degree. to 105.degree. C., the product of this reaction is slowly hydrolyzed at 90.degree. to 100.degree. C. with 0.5 to 1.0 mole water, based on the quantity of phosphorus atoms in the reaction mixture, the hydrolysis product is neutralized to a level of from 40 to 65% and preferably to a level of from 50 to 60%, based onthe acid number, with dilute alkali metal hydroxide, and the two phases formed are separated from one another after a residence time of 30 to 180 minutes at a temperature in the range of from 50.degree. to 95.degree. C.
摘要:
A process for reducing the residual content of free alkylating agent in aqueous solutions of amphoteric or zwitterionic surface-active agents by aftertreatment with ammonia, an amino acid containing 2 to 8 carbon atoms, or an oligopeptide.
摘要:
A process for the direct esterification of o-phosphoric acid with aliphatic fatty alcohols and/or adducts thereof with alkylene oxides and alkylphenol alkoxylates, in the presence of a substoichiometric quantity of a basic, inorganic or organic compound and a water-entraining agent.
