description The invention relates to 3,3', 4,4'-biphenyltetraformyl tetraoctylamine and a preparation method thereof, belongs to the technical field of chemical synthesis, and solves the problems of being large in addition amount, poor in tackifying performance, environment-unfriendly and high in cost of the existing thickener. The raw materials for preparing the 3,3', 4,4'-biphenyltetraformyl tetraoctylamine include 3,3', 4,4'-biphenyltetracarboxylic dianhydride and n-octylamine, and the mol ratio of n-octylamine to 3,3', 4,4'-biphenyltetracarboxylic dianhydride is (8-15): 1. The preparation method comprises the following steps: step 1: adding a solvent and the n-octylamine into a reaction vessel; step 2: adding the 3,3', 4,4'-biphenyltetracarboxylic dianhydride for reaction; step 3: cooling, adding a precipitating agent to precipitate a product; step 4: cooling and filtering by suction to obtain the 3,3', 4,4'-biphenyltetraformyl tetraoctylamine. The 3,3', 4,4'-biphenyltetraformyl tetraoctylamine realizes low content a
