초록

자동차 엔진용 thermostat에서 냉각수 온도제어를 위해 사용되는 wax의 제조 및 성분 분석을 실시하였다. 제조된 시료에 대해 lift 실험을 실시해 본 결과, 용제 추출법에 의해 제조된 시료가 자동차 엔진용 thermostat으로 사용 가능한 범위내에 있게 됨을 볼 수 있었다. 또한,원유의 pitch를 용제 추출한 후 감압 증류 및 산처리를 하면 보다 정밀한 wax를 제조 할 수 있음을 알 수 있었다.

The component analysis of wax for detecting temperature in automobile thermostat of the automotive engine and manufacture of it with distillation and solvent extraction were progressed. From the lift test results of prepared samples, it was found that the solvent extracted samples were in the proper range for use as an automobile thermostat of the automotive engine. And more accurate wax could be manufactured by high vacuum fractional distillation and acid treatment after solvent extraction from crude oil pitch.
