Method for producing highly efficient neopentyl glycol and apparatus for producing the same

摘要

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.
