摘要:
Surfactant mixtures which provide denser foams than the individual components consist of 50-90% by weight of an amine oxide corresponding to the formula RR'R"NO in which R is a primary alkyl group containing 6-24 carbons and R' and R" are independently selected from methyl, ethyl, and 2-hydroxyethyl and 50-10% by weight of an alkylbenzenesulfonate surfactant. Preferred mixtures are those in which the amine oxide is N-tetradecyldimethylamine oxide and the alkylbenzenesulfonate surfactant is sodium dodecylbenzenesulfonate.
摘要:
Surfactant mixtures which have performance and/or cost advantages over either component alone consist of 5-95% by weight of an amine oxide corresponding to the formula RR'R"NO in which R is a primary alkyl group containing 6-24 carbons and R' and R" are independently selected from methyl, ethyl, and 2-hydroxyethyl and 95-5% by weight of a fatty acid alkanolamide. Preferred mixtures are those in which the amine oxide is N-tetradecyldimetylamine oxide and the alkanolamide is cocodiethanolsuperamide.

摘要:
A tert-amine which contains an acid-activated color body precursor is treated to prevent it or a derivative thereof, e.g., an amine oxide, betaine, or quaternary ammonium compound, from turning pink when exposed to acidic conditions by contacting it with ammonium carbonate.

A tert-amine which contains an acid-activated color body precursor is treated to prevent it or a derivative thereof, e.g., an amine oxide, betaine, or quaternary ammonium compound, from turning pink when exposed to acidic conditions by contacting it with an amido compound containing a --CO.NH-- group.
摘要:
A tert-amine which contains an acid-activated color body precursor is treated to prevent it or a derivative thereof, e.g., an amine oxide, betaine, or quaternary ammonium compound, from turning pink when exposed to acidic conditions by contacting it with an acetylalkylcarbinol.
摘要:
A free-flowing granular heavy duty laundry detergent is made by blending with a detergent builder (e.g. Zeolite A) and optional other ingredients a discrete tert-amine oxide wherein the molecules correspond to the formual RR'R"NO.2H.sub.2 O in which R is a primary alkyl group containing 8-24 carbons; R' is methyl, ethyl, or 2-hydroxyethyl; and R" is independently selected from methyl, ethyl, 2-hydroxyethyl, and primary alkyl groups containing 8-24 carbons.

摘要:
Hydrocarbyl mercaptans are oxidized to sulfonic acids by reaction with aqueous hydrogen peroxide in the presence of an inorganic base (e.g. sodium hydroxide) and a tert-amine oxide. The product is in the form of a sulfonate salt. The reaction rate is increased and undesirable free-oil by-product is decreased by the inclusion of the amine oxide catalyst.
摘要:
Surfactant mixtures capable of providing a foamability performance equal to that of any of the components of the mixture at a lower cost comprise (1) an ethoxylated fatty alcohol, (2) a fatty acid alkanolamide, and (3) an alkyl sulfate.
摘要:
A non-aromatic tert-amine is oxidized with hydrogen peroxide at about 20.degree.-100.degree. C. by a carbon dioxide-accelerated high solids process in which discoloration of the amine oxide product is minimized by diluting the carbon dioxide before allowing it to contact the reaction mixture so that the entire reaction is conducted in an atmosphere composed of carbon dioxide and an amount of inert gas, such as nitrogen or air, which is at least equal in volume to the amount of carbon dioxide.
