1. To manufacture a lower melting hydrogenated fish oil having a good plasticity even in winter, the effect of dimethyl polysiloxane addition on hydrogenation of refined saucy oil was investigated under normal pressure. 2. The hydrogenation apparatus used was of batch type and made of stainless steel (SUS-27), and agitated by hydrogen blowing. Dimethyl polysiloxane with different M.W. and reduced nickels were used as catalysts and reactions were carried out at 200°C under constant condition of agitation, and catalyst concentration, etc. The weight ratios of the nickel and dimethyl polysiloxane to saury oil used were 0.2wt% and 0.015wt% respectively. 3. Addition of dimethyl polysiloxane to the nickel catalyst for cocatalysing purpose facilitated the control of hydrogenation, in slowing down the rate of hydrogenation as compared with the case without it. 4. The hydrogenated oil by together use of nickel and dimethyl polysiloxane, as compared with that by nickel alone, was much more superior in its consistency at low temperature, solid fat index, and in softening point. 5. Dimethyl polysiloxane of 500c.s. was superior in action than that of 100c.s.
