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:
The disclosure involves a novel amine ether acid salt surfactant. The amine constituent of the surfactant may include ether amines or fatty-based amines. The ether acid constituent of the surfactant, in particular, imparts liquidity to the surfactant. Hydrophobic regions may be included on both the amine and ether acid enhancing the surfactancy of the composition. The novel surfactant is versatile and is useful in many different applications.
摘要:
An improved asphalt roof-coating composition which includes asphalt cutback, clay, and a novel salt surfactant. The surfactant comprises an acid and alkoxylated fatty amines and alkoxylated ether amines. The novel surfactant amines are inexpensive and impart desirable physical properties to the composition.
摘要:
The disclosure involves an improved asphalt roof-coating composition which includes asphalt, clay, and a novel ether amine-acid-complex surfactant. The surfactant comprises an alkyloxyalkylamine, preferably having an alkyl chain with from 8 to 20 carbon atoms and an acid present in an amount in excess of the amount required to neutralize the amine. The composition is less expensive than prior art formulations and has improved viscosity and gel stability.
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.
