| titleOfInvention | A kind of preparation method of L- prolinol |
| abstract | The present invention relates to a kind of preparation methods of L- prolinol, use cheap L-Glutimic acid for raw material, with the modified ruthenium C catalyst catalysis L-Glutimic acid high-pressure hydrogenation reduction preparation L- prolinol of transition metal atoms.The modified ruthenium C catalyst catalytic activity is significantly higher than existing business ruthenium C catalyst, and the lactams hydrogenation reaction being difficult to realize in L-Glutimic acid can be made to go on smoothly.The preparation method of L- prolinol of the invention, process route is short, yield is up to 90% or so, post-processing is simple, and catalyst can be applied 20 times or more, is recycled and applies after sour water distillation, substantially green syt has been accomplished, there is no waste water, waste residue to generate, avoids the reduction such as boron hydride, lithium aluminium hydride reduction and generate a large amount of solid wastes and waste water, be especially suitable for large-scale industrial production. |
