Abstract
Solubilities, azeotropic compositions and some physical properties of di-sec-butyl ether (SBE), which is recently produced in commercial scale as a by-product in sec-butyl alcohol (SBA) manufacture, have been investigated.Mutual solubilities of SBE-SBA, SBE-diisobutylene, SBE-water and SBE-85 wt% aqueous sulfuric acid solution at 20°C, and liquid phase equilibrium diagram of ternary SBE-SBA-water at 20°C were measured respectively by a conventional method.Vapor-liquid equilibrium compositions of SBE-SBA and SBE-diisobutylene, and also azeotropic temperatures and compositions of SBE-water, SBE-SBA-water were determined. Other new physical data of SBE were presented.From the above experimental data, it seems plausible that SBE can be used as a useful solvent.
