摘要:
The disclosure is directed to novel detergent compositions having polyalkoxylated amine foam stabilizers. The new foam stabilizers of the inventive detergent compositions build or enhance foaming and are particularly useful because of their surprisingly mild, non-skin-irritating characteristics. Mildness is a requirement of components to be included in or used in applications such as liquid dish detergents, hand cleaners and car washes.
摘要:
Amino acid ester hydrohalide is produced by reacting amino acid, alcohol, and halocarbonyl compound represented by the formula: ##STR1## in the presence of an excess of the alcohol and under substantially anhydrous conditions, wherein X.sub.1 and X.sub.2 are each independently fluoro, chloro, bromo, trichloromethoxy or tribromomethoxy.
摘要:
The present invention relates to fuel additives, fuel compositions and methods of manufacture in which the additives are provided to impart desired properties to fuels. These properties include, without limitation, reduction of nitrogen oxide and particulate emissions from the exhaust stream of internal combustion engines using the fuels. Preferred embodiments of an additive form of the composition include a nitrogen-containing compound selected from the group consisting of urea, cyanuric acid, triazine, ammonia and mixtures thereof, a carrier blend comprising an alkoxylated alcohol, a polyalkylene glycol ester and an alkanolamide and water. The additive may be provided in a concentrate form by addition of a solvent or may be provided as a final form fuel composition. A method of additive manufacture and is disclosed.
摘要:
This invention is a method of preparing a quaternized amidoamine surfactant comprising reacting an amidotertiaryamine of formula with methyl halide and alkylene oxide, an aqueous quaternized amidoamine surfactant composition, a gelled aqueous composition comprising the quaternized amidoamine surfactant composition and one or more salts or alcohols and use of the gelled aqueous composition for fracturing subterranean formations.
摘要:
Poly(oxyalkylene) glycols and polymer-supported poly(oxyalkylene) alcohols are employed as phase-transfer reagents in blocking primary amino functionality of alkali metal salts of amino acids with a benzyloxycarbonyl group.
摘要:
Asphalt-based coating compositions and surfactants. The asphalt-based coating compositions have improved performance and comprise asphalt, clay, and a propoxylated alcohol-based ether amine salt surfactant.
摘要:
An improved asphalt roof-coating composition which includes asphalt, clay, and a novel hindered acid/amine salt surfactant. The surfactant comprises an acid constituent which has at least two alkyl groups bonded to the alpha carbon and an amine constituent comprising a variety of primary, secondary and tertiary amines. The composition has excellent physical properties including good viscosity and gel stability.
摘要:
Distillate fuel compositions containing an alkyl ether mono amine derived from a Guerbet alcohol are effective in reducing the formation of intake valve deposits in internal combustion engines. A preferred alkyl ether mono amine is derived from a highly branched butoxylated Guerbet alcohol containing 20 carbon atoms and having the formulaRO[C.sub.4 H.sub.8 O].sub.(4-8) CH.sub.2 CH.sub.2 CH.sub.2 NH.sub.2where R is a highly branched alkyl group having 20 carbon atoms that is derived from a Guerbet condensation reaction.
