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.

Claim (Index 1):
A process for synthesizing an amido alkyl betaine from a linear alcohol having from 8 to 22 carbon atoms, the process comprising\n a) in a first step, the linear alcohol having from 8 to 22 carbon atoms is condensed with an acrylonitrile to produce a \u03b2-alkoxy nitrile or with an alkyl acrylate to produce a \u03b2-alkoxy ester; b) in a second step, the \u03b2-alkoxy nitrile or \u03b2-alkoxy ester obtained from step a) is reacted with a short chain alcohol having from 1 to 4 carbon atoms to produce a \u03b2-alkoxy alkyl ester; c) in a third step, said \u03b2-alkoxy alkyl ester is reacted with an amino alkyl amine to produce an amido amine; and d) in a fourth step, said amido amine is reacted with an alkylating agent to produce the amido alkyl betaine.
