    • A method for producing propylene oxide in which the concentration of an organic peroxide in a reaction solution after an epoxidation step is from 20 to 5,000 ppm by weight based on the amount excluding propylene in the reaction solution, the method comprising an epoxidation step of reacting an organic peroxide with propylene in the presence of a catalyst to obtain propylene oxide and an alcohol, a propylene recovery step of recovering the unreacted propylene in the epoxidation step and recycling the resulting propylene as a raw material of the epoxidation step, and a propylene oxide purification step of distilling the propylene oxide obtained in the epoxidation step to obtain purified propylene oxide.
    • 一种环氧丙烷的制造方法,其中,环氧化工序后的反应溶液中的有机过氧化物的浓度为反应溶液中除丙烯以外的量为20〜5000重量ppm,该方法为使环氧化反应 有机过氧化物与丙烯在催化剂存在下反应得到环氧丙烷和醇,丙烯回收步骤,在环氧化步骤中回收未反应的丙烯,再循环得到的丙烯作为环氧化步骤的原料,并进行环氧丙烷净化 蒸馏在环氧化步骤中获得的环氧丙烷以获得纯化的环氧丙烷的步骤。

    • A pet excreta treating material made mainly of a ground material of plant origin and having a higher water absorbency in the third measurement than in the first measurement, a water absorbency of 3% to 30% by weight in the third measurement, and a specific gravity of 0.8 to 1.2 measured before the first water absorbency measurement. The water absorbency is measured by immersing a dried excreta treating material in 25° C. water for 3 seconds and calculating the weight increase by the equation below, which is taken as water absorbency (%). In the second and following measurements, the excreta treating material immediately after the preceding measurement is dried and immersed in 25° C. water for 3 seconds to obtain a water absorbency in the same manner.Water absorbency (%)=[(weight of excreta treating material after immersion−weight of excreta treating material before immersion)/(weight of excreta treating material before immersion)]×100.
    • 一种主要由植物来源的研磨材料制成并且在第三测量中具有比第一测量中更高的吸水性的宠物排泄物处理材料,第三测量中的吸水率为3重量%至30重量%,比重 在第一次吸水度测量之前测量为0.8至1.2。 通过将干燥的排泄物处理材料在25℃的水中浸渍3秒来测量吸水度,并通过以下等式计算重量增加,其被认为是吸水率(%)。 在第二次及以下的测定中,将上述测定后的排泄物处理材料干燥,浸入25℃水中3秒钟,以同样的方式得到吸水性。 吸水率(%)= [(浸渍前的排泄物处理材料的浸渍重量后的排泄物处理材料的重量)/(浸渍前排泄物处理材料的重量)×100。
