Summary:The present invention relates to sorbierite cracking process to prepare C2-C4 diatomic alcohol and polyol, and is especially the process of preparing sorbierite with corn material and hydrocracking sorbierite to prepare C2-C4 diatomic alcohol and polyol. The process includes hydrocracking sorbierite to prepare the mixture of C2-C4 diatomic alcohol and polyol at high temperature and high pressure in the presence of cracking sodium hydroxide and nickel/ruthenium catalyst, separation and refining to obtain single product. The production process of the present invention has the advantages of novel production path, unique technological condition, simultaneous production of several kinds of alcohol and high product quality. In addition, using grains, such as corn, as material to replace non-regenerable resource is significant.
