| titleOfInvention | A kind of method of synthesizing 3-hydroxybutyryl hydrazide |
| abstract | The invention provides a method for synthesizing 3-hydroxybutyryl hydrazide, comprising the following steps: placing polyhydroxyalkanoate and hydrazine hydrate in a reaction vessel, reacting at 40°C-70°C for 3-24 hours, and after the reaction Cooling to room temperature to obtain a homogeneous reaction solution, vacuum rotary evaporation of the homogeneous reaction solution at 90 ° C to remove the residual hydrazine hydrate solution to obtain a solid product, the solid product is soaked in chloroform twice to remove unreacted poly-3-hydroxyl Fatty acid esters or other by-products give 3-hydroxybutyryl hydrazide. Based on the quality of the raw material polyhydroxyalkanoate, the yield of 3-hydroxybutyrate hydrazide reached 130 wt%. The present invention realizes efficient conversion of poly-3-hydroxy fatty acid ester into 3-hydroxybutyryl hydrazide through one-step reaction, and has industrial application prospect. |
