摘要： An economic hydrogenation process is provided which significantly suppresses palladium catalyzer activity loss, for obtaining very high purity 1,4-CHDA through a simple operation. The process includes bringing the solution containing the hydrogenation reaction product of interest into contact with steam. The resultant products may include resins having excellent weather resistance or physical properties or high purity medical drugs. The process for preparing 1,4-cyclohexandicarboxylic acid is characterized by two consecutive steps. The first step includes the hydrogenation of a solution containing terephthalic acid in the presence of a palladium catalyzer in an acid resistant vessel or in a vessel layered with acid resistant material for preparing 1,4-cyclohexandicarboxylic acid. The second step includes contacting the solution containing 1,4-cyclohexandicarboxylic acid obtained in the first step with the steam, and extracting impurities moved to the steam.
摘要翻译：提供经济的氢化方法，其显着抑制钯催化剂活性损失，以通过简单的操作获得非常高纯度的1,4-CHDA。该方法包括将含有所需氢化反应产物的溶液与蒸汽接触。得到的产品可以包括具有优异的耐候性或物理性质的树脂或高纯度药物。制备1,4-环己烷二羧酸的方法的特征在于两个连续的步骤。第一步包括在耐酸容器中的钯催化剂存在下或在用耐酸材料层压制备1,4-环己烷二羧酸的容器中氢化包含对苯二甲酸的溶液。第二步包括使第一步骤中获得的含有1,4-环己烷二羧酸的溶液与蒸汽接触，并提取移入蒸汽中的杂质。

摘要： [Object]It is intended to provide a crystalline maltitol powder less prone to consolidation, which is free from the formation of a lump during delivery or storage thereof, does not require pulverization or re-classification in use, is easy to handle in transfer, package opening, addition or mixing to another food material, and so on, and allows for automated transportation and so on.[Means for Solving the Object]The crystalline maltitol powder less prone to consolidation is obtained by charging crystalline or powdery maltitol into a shelf type dryer, a tunnel-type dryer, a cylindrical container, or the like and subjecting the equipment or container to a treatment wherein an air having a temperature of 30 to 33° C. and a relative humidity of 5% is allowed to flow into the equipment or container from one side thereof and withdrawn out of the other side thereof at a space velocity of 11 to 12 for consecutive 24 hours. Even when the relative humidity is 45%, the crystalline maltitol powder less prone to consolidation can be obtained by combining therewith other conditions such as an appropriate space velocity of the feed of air and an appropriate treatment duration.
摘要翻译：本发明的目的是提供一种不易于固结的结晶麦芽糖醇粉末，其在输送或储存期间不形成块状物，不需要在使用中粉碎或重新分级，易于处理转移，包装开放，添加或混合到另一种食物材料等，并允许自动运输等。 [解决对象的手段]通过将结晶或粉末状麦芽糖醇装入搁板式干燥机，隧道式干燥机，圆筒形容器等中，并将该设备或容器置于处理其中温度为30〜33℃，相对湿度为5％的空气从其一侧流入设备或容器，并以11〜12的空间速度从其另一侧排出连续24小时。即使当相对湿度为45％时，通过与其它条件如空气进料的空间速度和适当的处理持续时间相结合，也可以获得不容易固化的结晶麦芽糖醇粉末。
