Abstract
วิธีหนึ่งสำหรับการประดิษฐ์ บิวทิรัลดิไฮด์ ซึ่งประกอบด้วย การแยกผลิต ภัณฑ์บิวทิรัลดิไฮด์ผสมที่เกิดขึ้นโดยกระบวนการไฮโดรฟอร์มิเลชันของโพรพิลีน ไปเป็น นอร์มัล-บิวทิรัลดิไฮด์ และไอโซบิวทิรัลดีไฮด์ และการทำให้ผลิตภัณฑ์นั้นบริสุทธิ์ โดยใช้ หอกลั่นซึ่งหอกลั่นนั้นถูกปฏิบัติ ภายใต้สภาวะซึ่งความดันที่ส่วนบนสุดของหออยู่ภายในช่วง ตั้งแต่ 0.001 ถึง 0.5 กก/ซม2 มาตรวัด และความดันที่ส่วนล่างของหอนั้นอยู่ภายใน ช่วงตั้งแต่ 0.05 ถึง 1.0 กก/ซม2 มาตรวัด One way for crafting Butyraldehyde It consists of the separation of the mixed butyraldehyde product produced by the hydroformization of propylene to normal-butyraldehyde. And isobutyraldehyde And the purification of the product using the distillation tower where the distillation tower is performed Under conditions in which the pressure at the top of the tower is within the range from 0.001 to 0.5 kg / cm2, the gauge and the pressure at the bottom of the tower are within the range from 0.05 to 1.0 kg / cm2.
