The maleic anhydride method is a process used to synthesize 4-butanediol. In this process, butanediol is first reacted with oxygen to obtain butanal, and then butanal is hydrogenated to obtain 4-butanediol in the presence of an alkali catalyst.

这个新工艺的一大特点是采用了更加和的催化剂，以提高反应的选择性和产率。同时，利用丁醛和氢气作为原料，减少了对昂贵和有限资源的需求。此外，新工艺还采用了优化的反应条件和操作流程，以降低能耗和废物排放。

A major feature of this new process is the use of more environmentally friendly and efficient catalysts to improve the selectivity and yield of the reaction. At the same time, the use of butyraldehyde and hydrogen as raw materials reduces the demand for expensive and limited resources. In addition, the new process also adopts optimized reaction conditions and operating procedures to reduce energy consumption and waste emissions.
