Yield:-
Reaction Conditions:
Stage #1:trimellitic Anhydride with tetrabutoxytitaniumInert atmosphere;
Stage #2:n-heptan1olInert atmosphere;
Steps:
7 Example 1
General procedure: To a reactor equipped with a stirrer, a condenser and a decanter, 500 g of cyclohexane 1,2,4-tricarboxylic anhydride, 1,280 g of 2-ethylhexanol,After adding 2 g of tetrabutyl titanate (TnBT), the esterification was initiated under a nitrogen atmosphere. After terminating the esterification, the unreacted alcohol was removed, and then transesterification was performed by adding 384 g of n-butanol. After the transesterification is terminated, the catalyst and product are neutralized with an aqueous alkali solution, and the unreacted alcohol and water are purified, so as to finally obtain the contents including 1.0wt%, 15.0wt%, 45.6wt%, and 38.4wt%, respectively, The tris(n-butyl) cyclohexane 1,2,4-triester,di(n-butyl)(2-ethylhexyl)cyclohexane 1,2,4-triester,Bis(2-ethylhexyl)(n-butyl)cyclohexane 1,2,4-triester,And tris(2-ethylhexyl)cyclohexane 1,2,4-triester composition
