WebPrimary Alcohols. Not all acid-catalyzed conversions of alcohols to alkyl halides proceed through the formation of carbocations. Primary alcohols and methanol react to form alkyl … Web27 Feb 2024 · BACKGROUND The ternary mixture of tetrahydrofuran (THF), ethanol and water contains multiple azeotropes with the sensitivity to pressure variation. The pressure-swing distillation (PSD) is a promising method to achieve the system's separation objective since it avoids many potential problems caused by adding a third component. RESULT
