The preparation method comprises the steps of adding porous cellulose acetate microspheres, cis,cis-2,4-hexadienedioic acid, (2R,3S)-1-carboxy-4-trifluoromethyl-2,3-dihydroxycyclohexan-4,6-diene, tetra-(trimethylsilyl ether)titanium, 1,2-bis(trimethylsiloxy)cyclobutene, benzoyl peroxideand water into a reaction kettle in parts by weight, heating for reaction, and washing and drying the product, so as to obtain the adsorbing material for 1,2-cyclohexane diisononyl phthalate.

Description

technical field [0001] The invention relates to a method for purifying diisononyl 1,2-cyclohexanedicarboxylate, in particular to a method for an adsorbent for purifying diisononyl 1,2-cyclohexanedicarboxylate. Background technique [0002] Diisononyl 1,2-cyclohexanedicarboxylate belongs to aliphatic polybasic acid ester and can be used as a plasticizer. Plasticizer is a polymer material additive widely used in industry. Adding this substance in plastic processing can make it more flexible, easy to process, and can be legally used for industrial purposes. [0003] CN101417950B discloses a method for preparing 1,2-cyclohexanedicarboxylic acid dibasic ester, the reaction system is composed of phthalic acid dibasic ester, hydrogen and catalyst; the reaction temperature is 100-250°C, and the reaction pressure is 3.0- 12.0MPa, the molar ratio of H2 to phthalic acid dibasic ester is 50~450, the liquid space velocity of phthalic acid dibasic ester is 0.1~2.5h-1; the catalyst is Al2...
