The invention discloses a new preparation method for a chiral sulfoxide compound and its salt, and a crystal form. The method is used for enantioselective preparation of the chiral sulfoxide compound existing in the form of a single enantiomer or in an enantiomer-rich form. After complexing of a diamide tartrate ligand and titanium, and in the presence of water, the effect similar to the circumstance in which alkali is added can be achieved without adding alkali, i.e. equal enantioselectivity and conversion rate. In addition, the invention also provides a new crystal form of S-(-)-omeprazole sodium.
