Abstract: 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 C and tin content of 14.62 for dibutyltin stearate, 78 80 C and 23.63 for dibutyltin salicylate, 155 157 C and 21.27 for diphenyltin salicylate, 149 151 C 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 CO2 asymmetric stretching vibration. General features of the spectra support the claim for the synthesis of these compounds.
