Synthesis, Spectral Characterization and Solubility Studies Of Some Organotin Carboxylates
International Journal of Science and Research (IJSR)
This study undertook the synthesis of four organotin compounds viz: dibutyltin stearate, dibutyltin salicylate, diphenyltin salicylate and triphenyltin acetyl salicylate using their salts and acids respectively. The melting range of the products was determined using a Griffin (MBF -595 -010 M) melting point apparatus. The characterization based on the tin content analysis showed a melting range of 60 -62 ᵒC and tin content of 14.62 for dibutyltin stearate, 78 -80 ᵒC and 23.63 for dibutyltin
... cylate, 155 -157 ᵒC and 21.27 for diphenyltin salicylate, 149 -151 ᵒC and 22.84 for triphenyltin acetyl salicylate. This showed that the increase in molecular weight of the organotin compounds increased their melting range. The spectral analysis was conducted using a Genesis series FTIR, Perkin -Elmer UV-visible spectrophotometer (Lambda 3D).The products showed intense absorption bands at 1560 -1601cm -1 which has been assigned to -CO 2 asymmetric stretching vibration. General features of the spectra support the claim for the synthesis of these compounds.
