Functionalization of Carboxylated MultiWalled Nanotubes with Stabilised Phosphorus Ylide

In this paper, the chemical Functionalization of Carboxylate multiwalled carbon nanotubes by methyl (triphenyl phosphoranylidene) acetate have been investigated. Phosphorus Ylides are important compound in organic chemistry. At first, methyl (triphenyl phosphoranylidene) acetate, synthesized from salt metod in two steps: the formation of the phosphonium salt and the deprotonation of the latter to form the ylide.  MWNTSlide is obtained through MWNTcocl with methyl (triphenyl phosphoranylidene) acetate, which is confirmed by FTIR, SEM and elemental analysis. The functionalized MWNTs were dispersed very well in solvent of dimethylformamide (DMF), and the high stability of dispersed suspension could be maintained for more than 1 week without MWNT precipitation. These Functionalization have been chosen due to P=C and C=O active sites in MWNTylide for future application.
