| titleOfInvention | The oxidation inhibitor triglycol is two-preparation method of [3-(3-tertiary butyl-4-hydroxy-5-aminomethyl phenyl) propionic ester] |
| abstract | The present invention relates to a kind of preparation method of oxidation inhibitor, relate in particular to a kind of preparation method of hindered phenolic oxidation inhibitor.Preparation method provided by the invention is divided into five steps: (1) raw material joins in the reactor and displaces wherein air; (2) heating makes the raw material melting and removes wherein light constituent and water; (3) add the zn cpds catalyzer; (4) 150～200 ℃ were reacted 2～9 hours down, and the methyl alcohol of generation is discharged reactive system; (5) cool to and add acid neutralization below 120 ℃.This method have the reaction times short, reaction solution is of light color, catalyst levels is little and characteristics such as easy removal.1. the product that utilizes this method to make has the purity height, quality is good, can directly apply to the production of derived product; 2. good stability, the long storage nondiscoloration; 3. remaining trace catalyst does not influence product stability energy and application performance. |
