Abstract
An experiment to examine the characteristics of pyrolysis of Methyl Ethyl Ketone Peroxide was conducted in an air-present environment, using TG-DTA. Decomposition starting temperature was decreased as the increase of 98% concentrated H₂SO₄ to the MEKPO and the maximum decomposition temperature of MEKPO was 116.8℃. The activated energy calculated from differential method of pure MEKPO, MEKPO with 1 wt%, 3wt%, and 5wt% of H₂SO₄ were 0.576㎉/mo1, 0.355㎉/㏖, 0.284㎉/㏖ and 0.258㎉/㏖ respectively.
Methyl Ethyl Ketone Peroxide의 열분해 특성을 파악하기 위하여 TG-DIA의 실험장치를 사용하여 공기 분위기 중에서 실험을 하였다. 그 결과 MEKPO에 98% H₂SO₄의 첨가량이 증가할수록 분해개시온도는 낮아졌으며, MEKPO의 열분해 최대온도는 116.8℃였다. 미분법에 의하여 얻어진 값으로부터 구한 활성화 에너지는 MEKPO와 MEKPO에 98%H₂SO₄ 1%, 3%, 5%를 첨가했을 경우에 각각 0.576㎉/㏖, 0.355㎉/㏖, 0.284㎉/㏖ 및 0.258㎉/㏖을 구하였다.
