    摘要： Processes for producing propylene glycol monoalkyl ether are described herein and include contacting propylene oxide and an alcohol in the presence of an alkali or alkaline earth metal alkoxide catalyst to produce an alkoxylation mixture including propylene glycol monoalkyl ether; distilling the alkoxylation mixture to produce a first overhead stream including propylene oxide and the alcohol and a first bottoms stream including propylene glycol monoalkyl ether; distilling the first bottoms stream to produce a second overhead stream including purified propylene glycol monoalkyl ether and a second bottoms stream including heavier byproducts; further distilling the second bottoms stream to form a resulting bottoms stream including caustic and heavier byproducts; introducing an alkali metal borohydride into at least a portion of the resulting bottoms stream to form an alkali metal borohydride containing stream; and introducing the alkali metal borohydride containing stream into one or more distillations upstream of recovery of the second overhead stream.

    摘要： This invention comprises a process and a system thereof comprising apparatuses for developing multi-component vapor mixture by heating of solution of reactants comprising one or more of diphenols, or diphenol derivatives, and an organic compound, wherein the organic compound is one which upon reacting in a vapor state in presence of a catalyst with diphenols, or diphenol derivatives, produces a monoalkyl ether of a dihydric phenolic compound; and wherein the entire solution of reactants completely transforms into a super-heated multi-component vapor using heaters without the use of thin film evaporator. The complete transformation of the entire solution of said reactants in to super-heated multicomponent vapor is achieved by heating the entire solution firstly by a pre-heater followed by further heating by a super-heater, further comprising removal of the unevaporated or condensed high boilers and tar to drain, and subjecting the superheated vapor to vapor phase reaction mediated by catalyst to get monoalkyl ether of a dihydric phenolic compound.

    摘要： A process for removing acetaldehyde from a mixture of methyl acetate, dimethyl ether and acetaldehyde comprising distilling mixtures derived from carbonylating dimethyl ether in the presence of a zeolite catalyst to generate an overhead stream depleted in acetaldehyde as compared to the feed mixture, a base stream depleted in acetaldehyde as compared to the feed mixture and a sidedraw stream enriched in acetaldehyde as compared to the feed mixture and withdrawing from the column the sidedraw stream enriched in acetaldehyde at a point above the feed point of the feed mixture to the column. Purified mixtures may be utilised as feedstock to processes for the co-production of acetic acid and dimethyl ether.

    摘要： The invention relates to a separation processing method for a product stream (g) of a reactor (4) used for the synthesis of dimethyl ether (z) from synthesis gas (e), said product stream containing at least dimethyl ether, methanol, water, carbon dioxide, carbon monoxide and hydrogen. The product stream (g) is fed into a liquid reflux-operated absorption column (6) at least partially in a gaseous state, wherein a gaseous top stream (m) is removed from the absorption column (6) at the top end, and a liquid bottom stream (p) is removed at the bottom end of the absorption column. At least part of the bottom stream (p) is fed into a first distillation column (5), wherein a gaseous transfer stream (q) containing dimethyl ether, and a stream (r) predominantly containing methanol and/or water are removed from the first distillation column (5). At least part of the top stream (m) is first cooled to a first temperature level and subsequently further cooled to one or more additional temperature levels, wherein a first condensate stream (n) is formed after the cooling to the first temperature level, and one or more additional condensate streams (s, t) are formed after the further cooling to the additional temperature level(s). Part of the first condensate stream (n) is used to form the liquid reflux, and at least part of the additional condensate stream(s) (s, t) are fed into an additional distillation column (9), from which a liquid stream (z) is removed at the bottom end, said liquid stream substantially containing dimethyl ether and having little or no carbon dioxide. The invention also relates to a corresponding separation plant and a plant (100) for producing dimethyl ether.
