Abstract:
     This invention provides a preparing method of greasing agent for leather. It has solved the problem that fish oil is esterifed by alcohol. This alcohol esterifying technology features that fish oil is esterified by alcohol under the action of activated catalyst-sulphuric acid and promoter-monochloro acetic acid and isovaleric alcohol. The weight proportions of reactants are as follows: fish oil: 100, alcohol: 10-19 (14-17 best), sulphuric acid: 5-10 (7-9 best), monochloro-acetic acid 0.5-1 (0.1-0.5 best) and isovaleric alcohol: 0.02-0.2 (0.05-0.1 best).
