| titleOfInvention | A kind of synthetic method of Rocryl 410 |
| abstract | The present invention discloses a kind of synthetic method of Rocryl 410, the step of this synthetic method is as follows: joined by methacrylic acid in reactor, add magnetic zeolite molecular sieve again, propylene oxide is added again after stirring, reactor is heated to 80 ~ 85 DEG C, reaction 2 ~ 3h, distillation obtains Rocryl 410.After the present invention adopts magnetic zeolite sieve peg-raking catalyst, without the need to re-using stopper, thus be conducive to product separation purifying, and the productive rate of Rocryl 410 can reach more than 96%, the recyclable recycling of catalyzer, reducing synthesis cost. |
