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 14):
A process for synthesizing the amido amine according to  claim 19  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 or an alkyl acrylate to produce a \u03b2-alkoxy nitrile or a \u03b2-alkoxy ester respectively; \n 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 1 to 4 carbon atoms to produce a \u03b2-alkoxy alkyl ester; and \n c) in a third step, said \u03b2-alkoxy alkyl ester is reacted with DMAPA to produce the amido amine, \n wherein in step a), the acrylonitrile or the alkyl acrylate is added in an equivalent from 0.8 to 2.0 with respect to the linear alcohol having from 8 to 22 carbon atoms.
