| titleOfInvention | Preparation method for preparing sulfitation fatliquor by use of waste oil |
| abstract | The invention belongs to the technical field of leather chemicals, and discloses a leather fatliquor containing sulfitation waste oil and a preparation method of the fatliquor. The method comprises the following steps: enabling the refined waste oil to react with monoethanolamine to obtain amidated waste oil; enabling the amidated waste oil to react with maleic anhydride to obtain succinate; and enabling the succinate to react with sodium hydrogen sulfite to obtain the sulfitation fatliquor. The method disclosed by the invention not only can meet the environmental need for treating gutter oil to increase the added value of the gutter oil, but also can provide the much-needed oil raw material for the leather industry; the raw materials are easily available, the cost is low, and the method is simple and convenient; moreover, the conditions in the preparation process are mild, the discharge of three wastes is avoided, and industrial production is easy to realize. |
