Results and discussion
Applicant's summary and conclusion
- Conclusions:
- The summary concludes that there are no experimental data on the stability of MOTC in water; however, based on data for other organotins [e.g., DOTC, MBTC, DBTL, DBT(2-EHMA), DOT(2-EHMA)], MOTC is expected to hydrolyze rapidly (within minutes to hours) in solution and the alkyltin moiety (MOT) is expected to be hydrolytically stable. The chloride in MOTC reacts initially with water to form mono-octyltin oxide (MOTO, which is less water soluble that MOTC) and HCl (which is quite dilute due to the low solubility of MOTC. Equilibrium reactions occur, but only in situations where there is an excess of chloride would any significant MOTC be reformed since MOTO is so insoluble and, therefore, less available for the replacement reaction to occur. At this time, no analytical technique exists that is capable of quantifying the entire MOTC compound with its chloride ligand, in dilute aqueous solution. None of the current analytical methods (e.g., alkyl or hydride derivatization) are acceptable for quantifying the resulting products of hydrolysis, as the parent compound, soluble impurities, and hydrolysis products will all be derivatized to the same final tetraalkyltin or alkyltin hydride compound, and there would be no differentiation between starting material and hydrolysis products.
