The invention relates to a method for separating methyl acetate-methanol-water by adopting an extractive distillation separation method with two-solvent lateral feed. The method comprises the following steps of: (1) carrying out two-solvent lateral feed on a methyl acetate, methanol and water mixed...
Process for the separation of methanol from water containing mixtures of methyl methacrylate and methanol 1. A method of separating off methanol from a watercontaining mixture of methyl methacrylate and methanol by azeotropic distillation, wherein n-octane, toluene or dimethyl carbonate is added to th...
The present invention relates to a salt efficiency of extraction and distillation separation integrated propionate - methanol - water system, comprising: a saturated saline as the extraction agent propionate - methanol - water system for salt extraction efficiency, extraction separation After the aqueous ...
by fractional distillation. Drying with CaO is unnecessary and wasteful. Anhydrous methanol can be obtained from "absolute" material by passage through Linde type 4A molecular sieves, or by drying with CaH2, CaSO4, or with just a little more sodium than required to react with the water present...
Caused by several azeotropes, distillation is not a preferred option for the separation of water from these mixtures [22]. In the scientific literature, also adsorption has been discussed as an option to separate water from these mixtures and results from preliminary experiments are reported showing...
and water and a heavier distillation fraction consisting essentially of methyl tertiary butyl ether, the lighter distillation fraction being decanted to remove water and to provide a distillate isobutylene fraction that is charged to a surge drum from which isobutylene is returned to the contact tower...
