Zusammenfassung:	The invention relates to the technical field of biodiesel preparation, in particular to a cottonseed oil gleditsia sinensis biological oleic acid preparation method which comprises the following steps: filling a reactor with a solid acid catalyst, adjusting the hydrogen pressure and flow of the reactor, slowly heating, introducing presulfurized oil, and completing presulfurization of the catalyst; carrying out pre-esterification on cottonseed oil gleditsia sinensis; the method comprises the following steps: introducing pre-esterified cottonseed oil saponin and straight-run diesel oil into a pre-vulcanized reactor, and carrying out hydrogenation mixing; compared with the prior art, the preparation method of the cottonseed oil gleditsia sinensis biological oleic acid has the advantages that the cottonseed oil gleditsia sinensis is pre-esterified, the pre-esterification rate reaches 95.93-96.11%, the acid value is reduced to 2.5-2.9 KOH/g, then the pre-esterified cottonseed oil gleditsia sinensis is added into s
