In 1994, 1.5 million tonnes of isopropyl alcohol were produced in the United States, Europe, and Japan. It is primarily produced by combining water and propene in a hydration reaction or by hydrogenating acetone. There are two routes for the hydration process and both processes require that the isopropyl alcohol be separated from water and other by-products by distillation. Isopropyl alcohol and water form an azeotrope, and simple distillation gives a material that is 87.9% by m… Web首页 / 专利分类库 / 一般的物理或化学的方法或装置 / 是有关分离的最通用的小类，但不包括从固体中分离出固体。 / 用其他的液体取代被置换的液体，例如，从湿的固体或从弥散的液体或从在液体内的固体中置换 / Method of cleaning an object
Web24 sep. 2024 · You should probably be more specific when talking about chemical substances, I only know "IPA" as an abbreviation for Indian Pale Ale. I'll assume that you mean isopropyl alcohol, which forms an azeotrope with water under atmospheric conditions, so it can't be separated with normal distillation and instead requires … WebA cost effective and energy efficient distillation technique for recovering acetic acid from a waste water stream containing acetic acid and water generated during terephthalic acid production employs a liquid-liquid extraction column and a downstream dehydration distillation column that operates under azeotropic or conventional distillation conditions …
WebEen azeotroop is een ( niet-ideaal) mengsel van twee of meer componenten waarvan de dampfase dezelfde samenstelling heeft als de vloeistoffase. Hierdoor is het niet mogelijk in één destillatiekolom een mengsel zuiverder te krijgen dan de azeotroop. In onderstaande figuur zijn van drie mengsels de T,x-diagrammen weergegeven.
