Micro-synthesis of zinc O, O-diisobutyldithiophosphate [32P] (ZDDP [32P]) was successfully attained with a yield of 33.9% from phosphorus [32P] pentasulfide and isobutyl alcohol. Because of the new experimental technique in this work, the time required to obtain the final product was remarkably shortened. It now takes less than 48h, which is quite satisfactory considering the very fast decay of phosphorus [32P].
Specific activity of the ZDDP [32P] obtained was 4.71 mCi/g-phosphorus, and the purity of the product was chemically and radiochemically high enough to be applied to ordinary tracer experiments. IR, elemental analyses, and autoradiography were employed to obtain the above conclusion.
