Epoxy resin powder coatings were improved by adding 6% dodecyl phosphate,(if the basic material is steels,as well must added potassium ferrocynide in 1/2 molar of phosphate).

The monoester,disester and phosphoric acid in dodecyl phosphate were determined by potentiometric titration.

Four novel bis(dodecyl phosphate) compounds,HDP,DGDP,BDP and PDP were synthesized using phosphorus oxychloride,diols(hexane-1,6-diol,diethylene glycol,butane-1,4-diol or hydroquinone) and dodecanol as raw materials,and purified by recrystallization in absolute ethyl alcohol.
