| description | The invention relates to the technical field of organic synthesis, in particular to a preparation method of chromium propionate, which comprises the following steps: S1, adding n-propionic acid, aminoacid, water and an organic solvent into a reaction kettle, and stirring to uniformly mix to obtain a mixture 1, S2, adding chromium oxide solid into the mixture 1 in S1 to obtain a mixture 2, S3, adjusting the rotating speed, stirring the mixture 2 in the step S2, and heating the reaction kettle to enable the mixture 2 to react until no solid residues exist, so as to obtain a product 1, and S4, drying the product 1 obtained in the step S3 under reduced pressure to obtain a lysine-containing crude product. The method is green, efficient, safe, environmentally friendly and beneficial to industrial preparation of chromium propionate.
本发明涉及有机合成技术领域，尤其是指一种丙酸铬的制备方法，包括以下步骤：S1，向反应釜中加入正丙酸、氨基酸、水和有机溶剂，搅拌至混合均匀，得到混合物1；S2，向S1中所述混合物1中加入氧化铬固体，得到混合物2；S3，调整转速，搅拌S2中所述混合物2，加热反应釜，使得混合物2反应至无固体残余，得到产物1；S4，对S3中得到的所述产物1减压干燥，即得包含赖氨酸的粗品。本发 |
