Abstract
For the purpose of development of an effective process for purified CHMI particles, a series of experimental researches on the synthesis of CHMI from CHMAIE, purification and precipitation of CHMI were preformed. It is turned out that n-heptane reflux imidation is more beneficial than toluene put-out imidation not only to the synthesis but to the precipitation of CHMI. By washing the synthetic CHMI with cold n-heptane twice, purified CHMI with 99.7% purity could be obtained at the cost of 11.7% weight loss. And CMHI particles were effectively prepared by spouting molten CHMI through the spiral nozzle with 3 mm diameter under the pressure of $1.5{\sim}2.0kg/cm^2$.
