N-ACYL AMINO ACID SURFACTANTS AND DERIVATIVES THEREOF
Surfactant compositions and derivatives with low amounts of impurities are disclosed along with a method of making the same. A surfactant composition includes greater than 80% by weight of N-acyl amino acid surfactant of formula (I) and is substantially free of solvents and/or NaCl. A process for preparing an N-acyl amino acid surfactant includes combining an amino acid, a waterless base and a fatty alkyl ester of formula (III) to form a mixture that includes an amino acid salt of formula (II). The temperature of the mixture is increased to form a reaction mixture. Alkyl alcohol is removed from the reaction mixture, and the reaction mixture becomes substantially clear.

Polyamides and amidoamines derived from hydroxyalkylpolyamines: epoxy curing agents with improved properties
Polyamide and amidoamine curing agents comprising a selectively modified amine. The selectively modified amine is formed by a substitution reaction between a polyamine and an epoxide, resulting in a multifunctional amine having a hydroxyl substituent. The curing agents are used to form epoxy resins having improved properties when cured.

Synthesis of bicyclo[2.2.2]octane derivatives
Provided is a process for the preparation of certain 1,4-bicyclo[2.2.2]octane derivatives. The new synthetic procedure involves treating 1,4-dimethylene cyclohexane with an oxidizing agent in the presence of a transition metal catalyst to afford an oxo-substituted bicyclo[2.2.2]octane species. This intermediate structure can then be further derivatized. The processes of this disclosure thus affords a novel and simplified means for the commercial production of a wide variety of bicyclo[2.2.2]octane derivatives.

Synthesis and evaluation of novel amido-amine cationic gemini surfactants containing flexible and rigid spacers
The invention concerns synthesized amido-amine-based cationic gemini surfactants with flexible and rigid spacers and different hydrophobic. These gemini surfactants were prepared by modified procedure through amidation of long chain carboxylic acids using 3-(dimethylamino)-1-propylamine followed by treatment with halohydrocarbons and showed excellent thermal stability and surface properties useful for various oilfield applications such as enhanced oil recovery.
