摘要： A method of producing phenol, acetone and alpha-methyl styrene. A mixture of cumene hydroperoxide and dimethylbenzyl alcohol is provided. The mixture is subjected to a first stage reaction in the presence of about 0.5 to 1.5 wt. % water and about 20 to 400 ppm sulfuric acid at a reactor pressure of about 450 to 760 mm Hg, a temperature of about 60 to 85° C., and a residence time of 4 to 45 minutes to produce a composition having an acetone to phenol mole ratio of about 1 to 1.5. The composition is subjected to a second stage reaction in the presence of about 0.5 to 3 wt. % additional water with a second stage reactor temperature of about 110 to 150° C. and a residence time of 0.5 to 30 minutes.

摘要： An improved method for the production of phenol, acetone and alpha-methyl styrene (AMS) from a cumene hydroperoxide and dimethylbenzyl alcohol (DMBA) mixture is described, wherein 0.5-5% additional water by weight is added prior to the final DMBA dehydration step, carried out in the presence of about 20-400 ppm mineral acid catalyst at 110-150° C. for 0.5 to 40 minutes residence time. The use of additional water allows greater flexibility in maintaining optimum temperature in the second stage over a much broader turndown range with fixed equipment, decreases the residual dicumyl peroxide (DCP) at the yield optimum for a given temperature, and increases the overall yield of AMS at optimum conditions at a given temperature.
摘要翻译：描述了用于从氢过氧化枯烯和二甲基苄醇（DMBA）混合物生产苯酚，丙酮和α-甲基苯乙烯（AMS）的改进方法，其中在最终DMBA脱水步骤之前加入0.5-5重量％的另外的水在大约20-400ppm的无机酸催化剂存在下，在110-150℃进行0.5至40分钟的停留时间。使用额外的水可以使固定设备在更广泛的调整范围内维持第二阶段的最佳温度更大的灵活性，在给定温度下以最优的产量降低残留的二异丙苯过氧化物（DCP），并提高AMS的总产率在给定温度下的最佳条件下。

摘要： The process of manufacturing an unsaturated mononitrile selected from the group consisting of acrylonitrile and methacrylonitrile comprising transporting a reactor effluent containing the unsaturated mononitrile to a first column where the reactor effluent is cooled with at least one aqueous stream, transporting the cooled effluent containing the unsaturated mononitrile into a second column where the cooled effluent is contacted with at least one second aqueous stream to absorb the unsaturated mononitrile into at least one second aqueous stream, transporting the second aqueous stream containing the unsaturated mononitrile from the second column to a first distillation column for separation of the crude unsaturated mononitrile from the second aqueous stream, and transporting the separated crude unsaturated mononitrile to a second distillation column to remove at least some impurities from the crude mononitrile, and transporting the partially purified crude unsaturated mononitrile to a third distillation column (product column) to further purified the crude unsaturated mononitrile, recovering the purified unsaturated mononitrile as a sidestream from the product column, introducing about 100 to about 2000 ppm of water in the form consisting of steam and distilled water into the bottom stream obtained from the product column and recycling at least part of the product bottom stream obtained from the product column to the bottom portion of the product column. In another aspect of the present invention the steam and distilled water is added directly to the product column.
