The invention discloses a wax crystal used for high viscous oil as well as an asphaltene dispersant. The dispersant is an organic compound containing oil-soluble long-carbon chain fatty alkyl function group and polar ester group, amido group, phenyl and amido function groups. The dispersant has the advantages of wide raw materials source, simple synthesis technology, cleaning and no pollution during processes, easy acquisition, and transport and preservation of the product. The dispersant has good salt-resistant performance, the mineralization-resistant degree can reach 220000 mg/L; The dispersant enables complex formulation with a plurality of pour-point depressants for usage, the effect is obvious, under condition that the dispersant enables complex formulation with a pour-point depressant, the usage amount is 150 ppm, compared with the crude oil with the pour-point depressant, the crude oil with high solidification point can be reduced with more 3 DEG C, and compared with a single pour-point depressant, th
