Abstract

본 발명은 세제류에 함유된 클로로 에틸렌류를 분석하는 방법에 관한 것으로서, n-헥산추출법에 의해 세제류중의 클로로 에틸렌을 분석하는 방법에 있어서, 분석하고자 하는 세제시료를 클로로 에틸렌의 비점이상으로 가열한 후, 응축시켜 얻은 액상을 분석하므로서, 시료중의 클로로 에틸렌 성분이 완전히 n-헥산으로 전이되어 기상전이 현상이 일어나지 않으므로 보다 정확하게 분석할 수 있고, 또한, 분석시간도 짧을 뿐만 아니라, 고상 또는 반고상시료와 액상시료의 분석조건이 서로 같은 세제류중의 클로로 에틸렌 분석방법을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a method for analyzing chloroethylene contained in detergents, the method of analyzing chloroethylene in detergents by the n-hexane extraction method, wherein the detergent sample to be analyzed is heated to the boiling point of chloroethylene After analyzing the liquid phase obtained by condensation, the chloroethylene component in the sample is completely transferred to n-hexane, so that gas phase transition does not occur, so that the analysis can be performed more accurately, and the analysis time is not only short, but also solid or semi-solid. It is an object of the present invention to provide a method for analyzing chloroethylene in detergents having the same analysis conditions as the sample and the liquid sample.

본 발명은 n-헥산추출법에 의해 세제류중의 클로로 에틸렌을 분석하는 방법에 있어서, 세제시료를 증류수와 n-헥산이 들어 있는 용기에 넣고 70℃ 이상으로 가열하여 증발시킨 후, 증발된 기체를 액화한 다음, 이 액화된 액체를 냉각된 n-헥산 함유증류수에 의해 분리하고, 븐리된 액상을 채취하여 크로마토그래피에 의해 클로로 에틸렌을 분석하는 방법을 그 요지로 하고 있다.The present invention is a method for analyzing chloroethylene in detergents by n-hexane extraction method, the detergent sample is placed in a container containing distilled water and n-hexane, heated to 70 ℃ or more and evaporated, the liquefied gas is evaporated Then, the liquefied liquid is separated by chilled n-hexane-containing distilled water, and the main liquid is collected and the chloroethylene is analyzed by chromatography.
