摘要:
A quaternary ammonium compound is combined with a water-soluble anionic surfactant having a hydrophile/lipophile balance (HLB) of 14 or above to form a biocidal/surfactant composition in which the amount of (ii) is up to 50 wt % of the total weight of these components. In the presence of water or other suitable aqueous media, such compositions appear to form a soluble charge complex. But whatever actually happens in the aqueous medium, the surfactant properties of the quaternary ammonium compound are improved without jeopardizing or impairing its germicidal properties.

Glyphosate formulations which are effective even when employed at dosages below the dosage currently recommended for post-emergent herbicidal or plant growth regulant use are described. They are formulated as water solutions or as powders or granules of (a) one or more agriculturally acceptable amine, alkali metal, alkylsulfonium, alkylphosphonium, sulfonylamine, and/or aminoguanidine salts of glyphosate as the only herbicide or plant growth regulant used in forming said composition; and (b) a trihydrocarbyl amine oxide surfactant as the only surface active component used in forming said composition. The amine oxide is (i) a single alkyl dimethyl amine oxide in which the alkyl group is a linear alkyl group having in the range of 10 to 14 carbon atoms, or (ii) a combination of two alkyl dimethyl amine oxides of (i), or (iii) a combination of at least one alkyl dimethyl amine oxide in which the alkyl group is a linear alkyl group having in the range of 10 to 14 carbon atoms and at least one dialkyl methyl amine oxide in which the alkyl groups are linear alkyl groups each having in the range of 8 to 12 carbon atoms. Optionally, one or more agriculturally acceptable substances none of which is a herbicide, or a plant growth regulant or a surfactant can be included in the formulation.

They are formulated as water solutions or powders or granules of (a) one or more agriculturally acceptable amine, alkali metal, alkylsulfonium, alkylphosphonium, sulfonylamine, and/or aminoguanidine salts of glyphosate; and (b) one or more water-soluble long chain monoalkyl sulfate or agriculturally acceptable salt or short chain ester thereof in which the long chain group is an alkyl group having in the range of about 10 to about 18 carbon atoms and is terminally substituted by such functionality.

Glyphosate formulations which are effective even when employed at dosages below the dosage currently recommended for post-emergent herbicidal or plant growth regulant use are described. They are formulated as water solutions or powders or granules of (a) one or more agriculturally acceptable amine, alkali metal, alkylsulfonium, alkylphosphonium, sulfonylamine, and/or aminoguanidine salts of glyphosate as the only herbicide(s) used in the forming composition; and (b) one or more water-soluble particular types of aliphatic hydrocarbyl sulfonic acid or agriculturally acceptable salt or ester thereof as the only surfactants used in forming the composition. The hydrocarbyl group of the sulfonate is a saturated aliphatic group having in the range of about 10 to about 18 carbon atoms and is terminally substituted by the foregoing functionality.
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.
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 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.
