    • Disclosed are a highly efficient neopentyl glycol preparation method and a device therefor. More particularly, disclosed are a method of preparing neopentyl glycol, wherein the method includes adding a hydroxypivaldehyde solution and hydrogen to a hydrogenation reactor that including a hydrogenation catalyst, wherein the hydroxypivaldehyde solution includes 6 to 30 % by weight of hydroxypivaldehyde, 35 to 70 % by weight of neopentyl glycol, 10 to 30 % by weight of alcohol, and 10 to 30 % by weight of water, and a device therefor.
      According to the present disclosure, a neopentyl glycol preparation method wherein separate heating is not required in a section of a feed vessel to an inlet of a hydrogenation reactor unlike conventional technologies to save energy, and, at the same time, by-products with a high boiling point are not generated in the section to prevent poisoning of a hydrogenation catalyst in a reactor due to the by-products with a high boiling point and increase a hydrogenation yield, and a device therefor can be provided.
    • 公开了一种高效新戊二醇制备方法及其装置。 更具体地说,公开了一种制备新戊二醇的方法,其中该方法包括将羟基新戊醛溶液和氢气加入到包含氢化催化剂的氢化反应器中,其中该羟基新戊醛溶液包含6至30重量%的羟基新戊醛,35至70重量% 的新戊二醇,10至30重量%的醇和10至30重量%的水,及其装置。 根据本公开内容,新戊二醇制备方法不需要在加氢反应器入口的进料容器部分中单独加热,与传统的节能技术不同,并且同时具有 为了防止由于高沸点的副产物引起的反应器内的加氢催化剂的中毒而使氢化收率提高,在该部分不产生高沸点,可以提供其装置。
