Title: Studies on Utilization of the Liver Oil of Deep Sea Sharks-XII
Abstract: A study has been conducted to prepare a viscosity improver for squalane by polymerizing squ-alane or partially reduced squalene, using 5% acid clay as catalyst at 210°C. (Fig. 1). Properties of the polymer and hydrogenated polymer and of those prepared from partially re-duced squalene are shown in Tables 2, 3, 5 and 6, respectively. From the study it has been found that the hydrogenated polymer is suitable as a viscosity im-prover for squalene (Table 4), and that oil prepared from squalane and hydrogenated polymer seemes to have the properties better than those of commercial watch oils. (Table 7).
