The invention belongs to the technical field of biological diesel and relates to ethyl ester type biological diesel prepared from prickly ash seeds with a high acid value and a preparation method of the biological diesel. Methanol is changed into ethanol, and a catalyst most applicable to the reaction process is selected. The preparation method comprises steps as follows: prickly ash seed oil and ethanol are mixed in proportion, preheated and then put into a reactor, the catalyst is added, and the mixture reacts while being stirred; a product is transferred to a separating funnel to be left to stand, and glycerol is separated out after the mixture is layered; a glycerol phase is washed with diluted hydrochloric acid, the yield of glycerol is tested, and the conversion rate of biological diesel is calculated; the ethyl ester type biological diesel prepared from the prickly ash seed oil is subjected to structural representation with FT-IR and GC-MS. The conversion rate of the ethyl ester type biological diesel
