Example 4
A compound A-2 was synthesized as follows.
To a 200 mL flask were added 7.51 g (30 mmol) of ditrimethylolpropane (manufactured by Tokyo Kasei Kogyo Co., Ltd.), 23.78 g (120 mmol) of cis,cis-cyclohexane-1,2,4-tricarboxylic acid-1,2-anhydride (manufactured by Mitsubishi Gas Chemical Company, Inc., H-TMAn-S (trade name)), and 31.29 g of butyl acetate (manufactured by FUJIFILM Wako Pure Chemical Corporation, reagent special grade), and the mixture was stirred at 100° C. for 6 hours under a nitrogen atmosphere. Thereafter, the mixture was cooled to room temperature (25° C.) to obtain a reaction solution.
As a result of 1H-NMR measurement of the obtained reaction solution, it was confirmed that the compound (A-2) represented by the formula (17) was contained.
In addition, the obtained reaction solution was subjected to GPC measurement under the same conditions as the GPC measurement described in the synthesis of the compound represented by the formula (16). As a result, the disappearance of the peak derived from ditrimethylolpropane and the peak derived from cis,cis-cyclohexane-1,2,4-tricarboxylic acid-1,2-anhydride was confirmed. As a result of calculating the GPC area fraction (content) of the compound (A-2) contained in the reaction solution, the content was 77%.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
