Abstract

본 발명은 불포화 지방산 에스테르 화합물의 에폭시화물의 제조방법에 관한 것으로서, 온도계, 환류냉각기 및 교반기가 부착된 4구 플로스크에 불포화 지방산 에스테르를 투입하고 서서히 교반하면서 70~80℃로 가열한 후 포름산을 상기 플라스크 내에 30분~1시간에 걸쳐 서서히 적하하고, 동시에 과산화수소와 인산의 혼합용액을 플라스크 내에 1~5시간에 걸쳐 서서히 적하하면서 상기 온도를 계속 유지하고 10~12시간 동안 반응시킨 후 유기층을 분리하여 pH가 중성이 될 때까지 수세한 후 감압건조 및 여과하여 불포화 지방산 에스테르 화합물의 에폭시화물을 제조하는 것을 특징으로 한다. 본 발명의 불포화 지방산 에스테르 화합물의 에폭시화물의 제조방법은 종래의 방법에 비해 반응효율이 높고, 제조공정이 간단하므로 반응시간이 크게 단축된 것으로서, 본 발명에 의해 제조된 불포화 지방산 에스테르 화합물의 에폭시화물은 산소함량이 월등히 높을 뿐만 아니라, 고 순도의 자연분해성 에폭시화물이다.The present invention relates to a method for producing an epoxide of an unsaturated fatty acid ester compound, wherein an unsaturated fatty acid ester is added to a four-necked flosk equipped with a thermometer, a reflux condenser, and a stirrer, and heated to 70 to 80 ° C. while gradually stirring formic acid. The mixture was slowly added dropwise into the flask over 30 minutes to 1 hour, and at the same time, the mixed solution of hydrogen peroxide and phosphoric acid was slowly dropped into the flask over 1 to 5 hours while maintaining the temperature and reacting for 10 to 12 hours. After washing with water until the pH is neutral, and dried under reduced pressure and filtered to produce an epoxide of the unsaturated fatty acid ester compound. The method for producing an epoxide of the unsaturated fatty acid ester compound of the present invention has a higher reaction efficiency and a shorter reaction time than that of the conventional method, thereby greatly shortening the reaction time. Silver is a highly pure, biodegradable epoxide that not only has a high oxygen content.
