Abstract
A high-efficiency method for the synthesization of N,N1,N2,N3-tetra(p-toluenesulphonyl) pentaery-thrityl tetramine is presented.Pentaerythrityl tetrabromide is mixed fully with sodium p-toluenesulphonamide whose excess amount is 15%,then put in a close Teflon-lined reactor,reacting for 6-8 hours at 210 ℃.The yield is over 95%.
