유기클로로산, 또는 에스타와 각종금속(아연, 규소, 마그네슘, 철)과의 여러 용매존재하(아세트나이트라일, 디옥센 및 토루엔)의 반응에서 얻은 반응성물, 또는 반응계중의 금속분석상태를 (n,γ)반응으로 제조한 각종방사성 금속트레이서를 사용하여 결정하였다. 유기클로로 금속 콤푸렉스의 용해도는 친수성용매에서는 현저하게 증가하였으며, 무극성용매에는 감소하였다. 이 사실은 회수된 금속, 또는 회수된 금속혼합물의 수세액중의 금속분포상태의 증가로서 확인되었다. 카보닐화합물 존재하에서 반응시켰 때에도 같은 사실을 나타내었다. 친수성용매중의 금속콤푸렉스의 용해도는 아연, 규소, 철 및 마그네슘이 순서로 감소되었으며 무극성용매하에서는 규소, 철, 마그네슘 및 아연의 순으로 감소되었다. 유기할로겐화물과 금속과의 반응생성물로 보통 예기되는 유기금속화물물은 전반응을 통하여 거의 없었다. 반응결과를 논의하였으며, 본반응과정에서 관찰한 용매의 경향에 관하여 논급하였다. Metal distribution in the reaction products and system of reactions between organo chloro acid or ester and zinc, silicon, magnesium, and tin under acetonitrile, dioxane, and toluene solvent were determined by means of radioactive tracer prepared by means of a (n, γ) reaction. It was found that the solubility of the organo halogen metal complex was markedly increased in a hydrophilic solvent and was decreased in a nonpolar solvent which resulted in an increased metal distribution in the recovered metal or water washing of the recovered metal mixture. This was also true in the case of the reaction conducted in the presence of a carbonyl compound. The relative increase of the solubility of the metal complex in a hydrophilic solvent was in order of zinc, silicon, tin and magnesium, and in a nonpolar solvent, it was in order of silicon, tin, magnesium, and zinc. There was no formation of organo metallics throughout the reaction sequence. The result was discussed and the observed solvent influence on the present reaction path was criticized. |
