| titleOfInvention | A kind of industrialized preparing process of the vivid red 150 of PU resistance to migration |
| abstract | The industrialized preparing process of the vivid red 150 of a kind of PU resistance to migration, belongs to pigment synthesis technical field.It obtains dispersion liquid with 3-amino-4-methoxyl benzanilide, water and hydrochloric acid through acid out salt-forming reaction；Obtain diazo solution in this dispersion liquid Sodium Nitrite aqueous solution diazo-reaction, then with 2-hydroxyl-3-naphthalenecarboxamide, 3-hydroxy-2-naphthoic acid generation coupling reaction, turn crystalline substance then through intensification and be obtained by reacting the vivid red of PU resistance to migration.The present invention is by adopting above-mentioned technology, and its reaction condition is gentle, and low for equipment requirements, the response time is short, modifying agent more typically and application difficulty less；The raw material used again is not halogen-containing, meets the product content of halogen of restriction on market, meets the novel environment friendly theme of promotion；The product bright in color light obtained, its thermostability reaches 230 DEG C, resistance to migration 5 grades. |
