The invention belongs to the field of chemical industry, and particularly relates to a method for efficiently preparing hydroxypivalaldehyde, the method comprises the following steps: firstly, a BaCeO3 catalyst or a transition metal/BaCeO3 catalyst is prepared by a simple coprecipitation method, and the hydroxypivalaldehyde is produced by using the BaCeO3 or transition metal/BaCeO3 as the catalystin a fixed bed under N2 protection. The process for preparing the catalyst is relatively simple and easy to operate, the prepared catalyst can be recycled; the obtained hydroxypivalaldehyde has highpurity, does not need to be rectified and purified, and can be directly applied to NPG production. 本发明属于化工领域，特别涉及一种高效制备羟基新戊醛的方法，首先，通过简单的共沉淀法制备BaCeO或过渡金属/BaCeO催化剂，然后，在固定床中，N保护状态下，将BaCeO或过渡金属/BaCeO作为催化剂，生产羟基新戊醛。本发明制备催化剂的过程比较简单，易于操作，且制得的催化剂可以被循环使用；制得的羟基新戊醛纯度较高，不需要进行精馏、提纯，可直接应用于NPG生产。
