Abstract	LPG에서 황화합물의 분배계수에 미치는 영향에 관하여 연구하였다. 분석 대상 물질은 알칸계통에 사슬형머캡탄이었다. LPG의 액체상 및 기체상의 조성을 기체크로마토그래피로 분석하였다. SAS를 사용한 다중회귀분석방법(MLR)으로 황화합물의 끓는점(Bp), 온도(Tk), 용매의 조성(C₄)과 관련되 분배계수를 다음과 같이 구할 수 있었다. K_pc=0.61222(±0.000959)Bp+0.26984(±0.06504)C₄0.003803(±0.0019993)Tk, N=24, F=14.851, R²_adj=0.6437. 분배계수에 미치는 중요 인자는 황화합물의 대기압에서 끓는점과 LPG의 조성이었다. n-부탄의 높은 조성 및 높은 온도에는 분배계수가 증가하여 가스의 취기 상승효과가 클 것으로 추측된다. Partition coefficient related composition of LPG are studied. Analysed sulfur compounds are ethyl mer-captan,n-propyl mercaptan and n-butyl mercaptan. The composition of liquid phase and gas phase in LPG are deter-mined by gas chromatography. The partition coefficient to related the boiling point of sulfur compounds, the temperature and the compositions of solvents, determined by using MLR(multiple linear regression) of SAS is follows; Kpc= 0.61222(±0.6578)-0.04670(±0.000959)Bp+0.26984(±0.06504)C4+0.003803(°æ0.0019993)Tk, N=24, F=14.851, R_adj²=0.6437. The boiling points of sulfur compounds at atmospheric pressure and the compositions of LPG effect mostly on partition coefficients. It is presumed that the gas odor elevating effects should be increased, where being on high tem-perature and larger amounts of n-butane.
