Abstract: A compound of general formula (I) or (II), wherein Rn and Rm independently represent a C3-C27 aliphatic group, R1 to R4, which may be the same or different at each occurrence, represent hydrogen or a C1-C8 alkyl group, X1 and X2, which may be the same or different at each occurrence, represent a linear or branched divalent hydrocarbon radical with 1 to 24 carbon atoms which can be optionally substituted and/or interrupted by one or more heteroatoms or heteroatom containing groups, and R5 and R6, which may be the same or different at each occurrence, represent a group selected from —O−, -Alk-CH(OH)—CH2—SO3— and -Alk-CO2— wherein Alk represents an alkylene group.

Abstract: The present invention relates to a new process for synthesizing an amido alkyl betaine starting from a linear alcohol having from 8 to 22 carbon atoms, to an amido alkyl betaine prepared by the process with increased viscosity in water, and also to use thereof as a viscoelastic surfactant in oil and gas applications and home personal care applications. The present invention also relates to a process for synthesizing an amido amine starting from a linear alcohol having from 8 to 22 carbon atoms, and to an amido amine prepared by the process.

Abstract: The present invention pertains to a process for the cross-ketonization (Piria reaction) between an aryl carboxylic acid and an aliphatic carboxylic acid using a metal-based compound and a slight or a moderate excess of aryl carboxylic acid. A good selectivity, up to 99 mol %, can be achieved. The aryl aliphatic ketone can be used for the preparation of surfactants and other downstream products.

Abstract: A mixture of two alkoxylates surfactants, one being an aryl aliphatic carbinol alkoxylate, the other one being a dialiphatic carbinol alkoxylate, said mixture being useful for stabilizing emulsions and dispersions used in agricultural or pharmaceutical formulations. The alkoxylates surfactants may serve as substitutes for nonylphenol ethoxylates (NPE) and tristyrylphenol ethoxylates (TSE).

Abstract: The instant invention relates to surfactants having the following formula (I) wherein: each of Ra and Rb is a a linear or branched, saturated or unsaturated, hydrocarbon chain, each of Rc and Rd is a alkyl chain having 1 to 10 carbon atoms, each of (E1) and (E2) is a divalent hydrocarbon radical, A is: a group a carboxylate group —COO− (optionally in all or part in the form —COOH); or a sulfonate group —SO3− (optionally in all or part in the form —SO3H). The invention also relate to the preparation of these surfactants and their use in oil extraction, especially in EOR applications.
