SULFUR-CONTAINING PALLADIUM/CARBON CATALYST, PREPARATION METHOD THEREFOR, AND METHOD FOR PREPARING P-PHENYLENEDIAMINE ANTIOXIDANT |
摘要 |
<p>Provided are a sulfur-containing Palladium (Pd)/carbon catalyst, a preparation method therefor, and a method of using the catalyst to prepare p-Phenylenediamine (PPD) rubber antioxidant. The method for preparing the sulfur-containing Pd/carbon catalyst comprises: loading Pd on an active carbon to obtain a Pd/carbon catalyst; then, preparing a slurry by mixing the Pd/carbon catalyst with a solvent; subsequently, adding a sulfide to the slurry, stirring at a predetermined temperature; finally, filtering, and acquiring the sulfur-containing Pd/carbon catalyst. Application of the sulfur-containing Pd/carbon catalyst in the preparation of the PPD rubber antioxidant not only improves the yield of the PPD rubber antioxidant and inhibits a material from being reduced into a corresponding alcohol, but also improves selectivity.</p> |
