| titleOfInvention | A kind of preparation method of amino calcium catalyst and the amino calcium catalyst of gained |
| abstract | The present invention provides a kind of preparation method of amino calcium catalyst, using calcium metal, urea, Organic Alcohol as raw material, the confined reaction at 80~100 DEG C is evaporated and adds alkane solvent and forms the slurried amino calcium catalyst after reaction.Present invention also offers with amino calcium catalyst made from the preparation method.For the amino calcium catalyst preparation method of the present invention using urea replacement of liquid ammonia cheap and easy to get as amino source, safe without cryopreservation, preparation process is gentle, easy to operate, and the manufacture cost of amino calcium catalyst can be greatly reduced, simplify technique.Activity height, the yield for the amino calcium catalyst catalysis epoxyalkane polymerization that the preparation method of the present invention obtains are good, can prepare polyethylene glycol oxide of the molecular weight ranges 5~8,000,000. |
