A Novel Method for Quaternization of Amino Acid/Peptide and Its Product Detection Using Electrospray Ionization Mass Spectrometry;

The solvent effect on quaternization of γ-chloropropyl trimethoxy siloxane and octadecyldimethylamine was studied.

The effect of inorganic iodide and solvents on the rate of the quaternization of 3-chloropropyl trimethoxy siloxane and octadecyldimethylamine was investigated.

Quaternary polyethyleneimine(QPEI) was prepared by tertiary amination and quaterisation amination.

Dimethyldiallylammonium chloride was synthesized from dimethylamine by quaterisation with allylchloride, and then copolymerized with acrylic acid and acrylamide to form a widely used cationic copolymer.

This paper sets forth a method in which as raw materials styrene-divinglbenzene synthesizes -4HCrO quaternary ammonium salt oxidizing agent as a result of chloromethylation, quaterisation and chromadizing; and also makes investigation into the fact that chlorine content of chloromethylation resin and the exchange capacity of chromadizing resin vary with time.
