The invention discloses a method for producing a high latent heat phase-change material. The method comprises the following steps: by taking an F-T synthetic product as a hydrogenation raw material, performing hydro-conversion under the effect of a catalyst; distilling a hydrogenation product, thereby acquiring a suitable boiling range component as a sweating raw material; sweating, thereby producing a target product. According to the method provided by the invention, on the basis of common sweating technology, a high-temperature constant-temperature stage is added in a cooling process; air flow is utilized to carry out a liquid component by a wax layer so as to forcefully separate a solid component from the liquid component in the sweating process; optimally, the aqueous solutions of more than two matters capable of reacting and generating gas are respectively emulsified and sweated and quick discharging of the liquid component is benefited. The method disclosed by the invention has the advantages of low equ
