Paragraph 0053; 0054, (2016/10/20)
The invention provides a preparation method of a bidentate phosphine rhodium complex. The method includes the steps of: in a nitrogen protection condition, adding an alcoholic solution of rhodium trichloride hydrate and a formaldehyde solution drop by drop to an alcoholic solution of a bidentate phosphine complex in order; continuously carrying out reaction for 10-60min at 50-120 DEG C; and separating the generated bidentate phosphine rhodium complex after a mixing solution is cooled. The preparation method of the bidentate phosphine rhodium complex has the advantages that raw materials are easily available, and the preparation method is simple and easy to operate, and overcomes the problem that the steps of the present preparation method are tedious and difficult to operate. The invention also provides the bidentate phosphine rhodium complex prepared by the above preparation method, and application of the bidentate phosphine rhodium complex as a catalyst to an alkene hydroformylation reaction.
