Title:
METHOD FOR PRODUCING CATIONIC LIPID
Document Type and Number:
WIPO Patent Application WO/2016/093205
Kind Code:
A1
Abstract:
Provided is an industrial method for producing a cationic lipid with which it is possible to efficiently obtain a high-purity cationic lipid without requiring special equipment. A cationic lipid represented by formula (1) and a tetraalkylammonium salt having X- are mixed in an organic solvent, tetraalkylammonium iodide is precipitated by concentrating the filtrate obtained by filtering out the precipitated tetraalkylammonium iodide, and a cationic lipid represented by formula (2) is obtained.
