On the Chemical Properties of Commercial Organofluoro Rodenticide

시판(市販) 불소계(弗素系) 살서제(殺鼠劑)의 성분특성(成分特性)

In order to know about chemical properties of a commercial organofluoro rodenticide, $Kiratol-F^{(R)}$, this experiment was carried out. Chemicals from different two manufactures were compared with synthetic compound by Gas Chromatograph and NMR-spectrophotometer. The results were as followings; 1. The permitted active ingrdient of Kiratol-F, ${\beta}$-fluoro-ethylacetate, was not identified, but ${\beta}$-fluoroethanol was a new active ingradient. 2. Kiratol-F was a water soluble liquid containing samll amounts of chloroethanol in impurity. 3. Yield of synthetic fluoroethanol was about 50%, but the composition of the reactant was assumed ${\alpha}$- and ${\beta}$-fluoroethanol, and the light condition was better than the dark in yield. 4. It was not become known any breakdown of active ingredient by the different dilutions and time intervals. So, the secondary toxicity of Kiratol-F might be relatively higher than imagination.

시판중인 유기불소계 살서제인 키라톨-F 제의 화학적(化學的)특성을 알아보기 위해 본 실험을 수행하였다. 시료는 제조회사에 따라 두 종류를 비교 검토하였으며, 아울러 실험실내 합성을 통해 주성분을 확인하고자 시도하였으며 그 중요한 결과는 아래와 같다. 1. 시판 키라톨-F제의 주성분으로 제시된 ${\beta}$-fluoroethanol acetate 는 확인할 수 없었으며, 그대신 ${\beta}$-fluoroethanol 이 주성분으로 밝혀졌다. 2. 시판 키라톨-F제는 수용액이며 chloro ethanol 이 소량 함유되어 있다. 3. 실험 실내에서 합성한 fluoroethanol은 ${\alpha}$-와 ${\beta}$-fluoroethanol 의 혼합물로 추정되며 합성수율은 광조건이 암조건보다 훨씬 높은 것으로 나타났다. 4. 키라톨-F제의 희석 배율에 따른 경시변화를 조사한 결과, 주성분의 분해는 일어나지 않았으며, 따라서 2차독성의 가능성이 매우 높은 것으로 생각된다.
