The invention relates to a catalyst for preparing n-Butyl butyrate by n-butanal and a preparation method thereof. The catalyst is prepared by the following steps: using a hydroxy-enriched porous organic polymer as a substrate, and forming a complexation structure of Ru on the surface of the substrate; firstly preparing a hydroxy-enriched porous organic polymer material POP; adding tert-butyl lithium or n-butyl lithium, and preparing a polymer POP-Li; and adding ruthenium salt to obtain a polymer POP-Ru. The catalyst has the characteristics of good stability, repeated use, and higher reaction conversion rate and selectivity. The preparation method is capable of creatively fixing Ru ions on the surface of the catalyst, a new idea is provided for the preparation of the catalyst, and the catalyst has the significant application value. 本发明涉及种正丁醛制备正丁酸正丁酯的催化剂及其制备方法。催化剂以富含羟基的多孔有机聚合物为基底，在其表面形成Ru的络合结构；首先制备富含羟基的多孔有机聚合物材料POP；然后加入叔丁基锂或者正丁基锂，制备聚合物POP-Li；加入钌盐，得到聚合物POP-Ru。本发明的催化剂具有稳定性好，可重复利用，反应的转化率和选择性都较高的特点。本发明创造性的将Ru离子固定在催
