摘要:
Amine oxides, such as amine oxide dihydrates, which have become discolored by being prepared from tert-amines and hydrogen peroxide in a liquid medium constituting not more than 50% of the weight of the reaction mixture and in the presence of carbon dioxide are bleached by exposing them to visible light, preferably incandescent light having a luminosity of at least about 1750 lumens.
摘要:
A pourable amine oxide composition which is suitable for use in detergent compositions is obtained by reacting a tert-amine with aqueous hydrogen peroxide in a nonionic surfactant as the sole organic solvent, at least a portion of the nonionic surfactant being a fatty alkanolamide corresponding to the formula ZC(O)NZ'Z" in which Z is an alkyl group containing 4-30 carbons, Z' is hydrogen or an alkyl or hydroxyalkyl group containing 1-3 carbons, and Z" is a hydroxyalkyl group containing 1-3 carbons. When the composition has a low water content, it is suitable for use in water-sensitive formulations, such as bar soaps and detergent concentrates.

摘要:
Quaternary ammonium halides are prepared in solid form by reacting an alkyl or aralkyl halide with ammonia or an amine in a liquefied gas as the solvent.
摘要:
The rewettability of laundered fabrics, such as cotton fabrics, that are softened by the use of a laundry rinse is improved by using as the laundry rinse a rinse comprising an aqueous solution of a mixture of 20-75% by weight of N-octadecyl-N,N-dimethylamine oxide and 80-25% weight of N-dihydrogenatedtallow-N,N-dimethylammonium chloride as the fabric softener.
摘要:
Betaines are produced in solid form by reacting a tert-amine with a haloalkanoate salt when the reaction is conducted in a liquefied gas as the solvent. In a preferred embodiment, the tert-amine is an N-alkyldimethylamine, the haloalkanoate is sodium chloroacetate, and the liquefied gas is carbon dioxide.

A pourable amine oxide composition which is suitable for use in detergent compositions is obtained by reacting a tert-amine with aqueous hydrogen peroxide in a nonionic surfactant as the sole organic solvent, at least a portion of the nonionic surfactant being a fatty alcohol ethoxylate or other compound corresponding to the formula Z[OC(Z')HCH.sub.2 ].sub.m OH in which Z is an alkyl group containing 4-30 carbons, Z' is hydrogen or an alkyl or hydroxyalkyl group containing 1-3 carbons, and m is an integer of 1-100. When the composition has a low water content, it is suitable for use in water-sensitive formulations, such as bar soaps and detergent concentrates.
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 inorganic sulfite selected from alkali metal sulfites and bisulfites, preferably sodium sulfite, at a temperature above 100.degree. C.
摘要:
Betaines are produced in solid form by reacting a tert-amine with an alkyl haloalkanoate and hydrolyzing the resultant quaternary ammonium ester when the tert-amine/alkyl haloalkanoate reaction is conducted in a liquefied gas as the solvent and the hydrolysis is conducted in a liquefied gas solvent or a polar aprotic solvent in which the betaine is substantially insoluble. In a preferred embodiment, the tert-amine is an N-alkyldimethylamine, the haloalkanoate is ethyl chloroacetate, and the liquefied gas is carbon dioxide.
