| titleOfInvention | A kind of recoverying and utilizing method of AVM hereinafter Batan intermediate production waste liquid |
| abstract | The present invention relates to a kind of recoverying and utilizing methods of AVM hereinafter Batan intermediate production waste liquid, using generated waste liquid in AVM hereinafter Batan intermediate 5R- benzyloxy amino piperidine -2S- formic acid ester oxalate IIb production process as starting material, 5- benzyloxy imino piperidines -2S- formic acid esters III is generated through peroxidating, the chosen property reduction of III, chiral crystallization split, solid 5R- benzyloxy amino piperidine -2S- formic acid ester oxalate IIb are obtained by filtration, and gained filtrate repeats the above oxidation, reduction, split process.The neutralized preparation 5R- benzyloxy amino piperidine -2S- formic acid esters IIa of compound IIb, can prepare AVM hereinafter Batan I using gained compound IIa or compound IIb.Operation of the present invention is easy, improves atom utilization, the final total recovery of compound IIb advantageously reduces cost up to 99.0% or more, advantageously reduces the waste liquid of AVM hereinafter Batan, be conducive to environmental protection. |
