    • A method of distilling and purifying high-melting materials while preventing corrosion of the device, contamination of the distillate and degeneration; and a device used therefor. The distillation purification device comprises an evaporating section (A) for evaporating high-melting organic materials subsequently to melting thereof, and collecting sections (B, C) for condensing and collecting the evaporated gas, the temperature of the collecting sections being substantially stepwise or continuously decreasing toward the downstream side, at least the evaporating section and part of the collecting section being made of a material that can be heated through electromagnetic induction by an dielectric coil, the inner surface of the device contacting high-melting organic materials being made of a material that is inert to such high-melting organic materials. Effecting distillation using this distillation purification device makes it possible to selectively collect only the intended substance in the collecting sections held at a specific temperature by electromagnetic induction; thus, a product of high purity can be obtained at a high yield.
    • 一种蒸馏和净化高熔点材料同时防止装置腐蚀,馏出物污染和退化的方法; 和用于此的设备。 蒸馏净化装置包括用于蒸发其熔融后的高熔点有机材料的蒸发部分(A)和用于冷凝和收集蒸发气体的收集部分(B,C),收集部分的温度基本上是逐步或连续的 至少蒸发部分和收集部分的一部分由可通过电介质线圈的电磁感应加热的材料制成,该装置的内表面与高熔点有机材料接触,由 对这种高熔点有机材料是惰性的材料。 使用该蒸馏精制装置进行蒸馏,可以通过电磁感应选择性地收集在特定温度下保持的收集部中的目的物质; 因此,可以高产率获得高纯度的产物。
