Following our succes in the synthesis of some derivatives of organotin(lV) carboxylates, in this work we reported the corrosion inhibitor study of three dibutyltin(IV) compounds using ligands of 2-, 3- And 4-nitrobenzoic acid. All the three synthesized compounds were characterized by spectroscopy techniques and also based on the microanalytical and physical data. The corrosion inhibition was evaluated with potentiodynamic polarization technique using ER644 Integrated Potentiostat eDAQ type on mild steel hot rolled plate (HRP) in DiMSO-HCl solution. The results indicated that the these compounds showed interesting inhibition activity with percentage of inhibition efficiency (% IE) of 59.3, 60.5 and 61.2 % for dibutyltin(IV) 2-nitrobenzoate, 3-nitrobenzoate and 4-nitrobenzoate, respectively. These three dibutyltin(IV) compounds have been shown promising to be potentially used as anticorrosion inhibitors.

Paragraph 0025, (2017/09/02)
The invention relates to a preparation method of high-purity dibutyltin oxide. The preparation method comprises the steps of carrying out synthetic reaction on the raw materials including dibutyltin oxide and alkali in a heterogeneous system of an organic solvent and a water solution, and finally carrying out centrifugation and drying, so as to obtain a dibutyltin oxide finished product. The product prepared by virtue of the preparation method is high in purity; the organic solvent and a surfactant are respectively used as a solvent and an extraction medium in a preparation process, and dibutyltin oxide particles generated by alkalization reaction are rapidly transferred into an organic phase by virtue of an absorption effect of the surfactant in the alkalization reaction process, so that the product is separated from water rich in chloride ions; the organic phase containing dibutyltin oxide is collected through layering separation, toluene is recycled through distillation, and then high-purity dibutyltin oxide is prepared; the content of the chloride ions in the product is effectively controlled to be less than or equal to 50ppm, so that the industrial water pollution is reduced.

The synthesis of 3 compounds of a series of dibutyl(IV) di-4-chlorobenzoate, diphenyl(IV) di-4-chlorobenzoate and triphenyltin(IV) 4-chlorobenzoate have successfully been performed by reacting the dibutyltin(IV) dichloride, diphenyltin(IV) dichloride and triphenyltin(IV) chloride respectively via the dibutyltin(IV) oxide, diphenyltin(IV) dihydroxide and triphenyltin(IV) hydroxide with 4-chlorobenzoic acid. All compounds synthesized were well characterized by 1H and 13C NMR, IR and UV-Vis spectroscopies as well as based on the microanalytical data. The anticorrosion activity of these compounds were tested on Hot Roller Plate (HRP) mild steel in DMSO-HCl solution using potentiodynamic method. The results revealed that the triphenyltin(IV) 4-chlorobenzoate clearly showed the strongest inhibitor activity compared to the other derivatives, while diphenyltin(IV) compounds were better than that of dibutyltin(IV) analogous. The results reported here indicated that the optimal activity were depended on the ligand attached to the metal centre and might also be related to the number of carbon atoms present in the organotin(IV) used.
