    • Provided are a resin tube for a guide wire, a method for manufacturing a resin tube for a guide wire, and a guide wire, configured such that the resin tube makes point contact in the axial direction with an object of contact at working site, thereby reducing frictional resistance and yielding excellent sliding properties, while also being prevented from kinking and collapsing, and having excellent buckling resistance. The resin tube for a guide wire is characterized in that the outer shape of a cross-section perpendicular to the axial direction is polygonal, elliptic, or irregular, that the resin tube is twisted in a helical shape about a deep inner-core hole as the axis of twisting, the deep inner-core hole extending in the axial direction and allowing a core wire to be inserted therein, and that the resin tube is provided with a trunk section having an undulation on the outer surface caused by the twisted eccentric wall thickness.

    • There is provided a method for obtaining a target organic compound such as an alkyladamantyl ester efficiently by purifying a crude organic compound which contains, as impurities, sublimable materials which start to sublime at temperatures lower than a boiling point of the target organic compound by use of such a simple method as distillation during its production process, without being adversely affected by adherence of the sublimable materials.The distillation is carried out in the presence of a compound having a boiling point which is lower than a boiling point of the target organic compound, e.g., a carbonyl-group-containing compound. For example, 2-methyl-2-adamantyl methacrylate (boiling point: 92° C./0.3 mmHg) containing sublimable impurities such as adamantane (sublimation starting temperature: room temperature or lower) is distilled in the presence of 1,3-dimethyl-2-imidazolidinone (boiling point: 225° C.).
    • 提供了一种通过纯化粗制有机化合物来有效地获得目标有机化合物如烷基金刚烷基酯的方法,所述粗制有机化合物含有作为杂质的可升华材料,其在低于目标有机化合物的沸点的温度下开始升华, 这种简单的方法是在其生产过程中的蒸馏,而不受升华材料的粘附的不利影响。蒸馏在沸点低于目标有机化合物的沸点的化合物的存在下进行, 例如含羰基化合物。 例如,将含有金刚烷(升华开始温度:室温以下)的升华性杂质的甲基丙烯酸2-甲基-2-金刚烷酯(沸点:92℃/ 0.3mmHg)在1,3-二甲基 -2-咪唑啉酮(沸点:225℃)。
