Abstract:
     This invention provides a technology for removing offensive smell of fish oil which is used in a greasing agent for manufacturing leather. The problems of original technology that the offensive smell of fish oil can not be removed and the store duration is short have been solved. Its features are as follows: 100 portions of fish oil are treated by 1-4 (1-2 best) portions of formaldehyde and 0.1-1 (0.3-0.8 best) portions of phenol; then, are oxidized with H2O2 or Na2O2, whose weight is 0.5-4% that of fish oil, and air at 65-80 deg. C; next, react with hydroxylamine whose weight is 1.5-15% (2-5% best) that of fish oil; finally, 0.2 portions of phenol, 0.15 portions of antioxygen and 0.05 portions of alkaloid are added in.
