Summary: | The present invention relates to a method for preparing a diester-based material and, more specifically, to a method for preparing a diester-based material which is performed as a process of continuously preparing a diester-based material comprising reaction units in which a total of n reaction units from a first reaction unit to an n^th reaction unit are serially connected, wherein the reaction units comprise a reactor for inducing esterification of a dicarboxylic acid and alcohol. The method comprises the steps of: preparing a reaction product by inducing esterification of the dicarboxylic acid and alcohol through the reactor of the first reaction unit, and supplying a lower discharge stream comprising the reaction product to a rear reaction unit via a lower discharge line; and supplying a liquid material via a liquid supply line connected to the lower discharge line of the reactor of the first reaction unit.
