METHOD OF PRODUCING ALKYL IMIDAZOLINE Russian patent published in 2013 - IPC C07D233/06 

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry and specifically to a method of producing alkyl imidazoline of formula via thermocatalytic reaction of a fatty acid, where R is a C₈-C₂₂ hydrocarbon radical, which is unsaturated or saturated, with an alkyl polyamine of formula: H₂N(CH₂CH₂NH)_nCH₂CH₂NH₂, where n=2-8 in the presence of a catalyst, 1.5 pts.wt sodium glycerate, 10% sodium solution in glycerine, a mixture of compounds of formula C₃H₅O₃Na₃, C₃H₆O₃Na₂, C₃H₇O₃Na, per 1.0 pts.wt disodium salt of 1-hydroxyethylene diphosphonic acid of formula CH₃C(OH)(PO₃H)₂Na₂. Catalyst consumption is equal to 1 wt % to the mixture of starting reactants.

EFFECT: low temperature of the process and shorter synthesis time, high output of the product and improved colour index.
