    • A process for producing high purity isopropyl alcohol. In one embodiment, the process includes the steps of: (a) feeding a feed stream comprising at least about 99.9 wt. % isopropyl alcohol into a separation column; (b) separating the isopropyl alcohol into an overhead stream taken overhead from the separation column and a bottoms stream taken as bottoms from the separation column; and (c) removing the high purity isopropyl alcohol at a point: (i) below where the feed stream enters the separation column but above the bottoms stream, or (ii) above where the feed stream enters the separation column but below the overhead stream. The high purity isopropyl alcohol has a metals content of less than about 1 ppb and a water content of less than about 100 ppm. Optionally, the process includes the step of passing the high purity isopropyl alcohol through an ion exchange resin after removing the high purity isopropyl alcohol from the separation column, thereby forming an ultra-high purity isopropyl alcohol that contains less than 100 ppt of any metal impurity.
    • 一种生产高纯度异丙醇的方法。 在一个实施方案中,该方法包括以下步骤:(a)进料包含至少约99.9wt。 %异丙醇进入分离柱; (b)将异丙醇分离成塔顶馏出物,塔顶馏出塔和从分离塔中取出的底部物流; 和(c)在以下点:(i)除去高纯度异丙醇,其中进料流进入分离塔但高于塔底流,或(ii)上述进料流进入分离塔但低于塔顶流 。 高纯度异丙醇的金属含量小于约1ppb,水含量低于约100ppm。 任选地,该方法包括在从分离塔中除去高纯度异丙醇之后使高纯度异丙醇通过离子交换树脂的步骤,从而形成含有小于100ppt的任何金属杂质的超高纯度异丙醇 。

    • This invention relates to a process for the production of an alcohol, the process comprising (a) reacting an olefin and water in the presence of a catalyst under conditions sufficient to form a crude alcohol stream comprising alcohol, and a dialkyl ether; (b) separating at least a portion of the crude alcohol stream into an alcohol-containing stream and a dialkyl ether stream; (c) contacting at least a portion of the dialkyl ether stream with an ether decomposition catalyst, the ether decomposition catalyst comprising a mixed metal oxide having the following composition XmYnZpOq where X is at least one metal selected from Group 4 of the Periodic Table of Elements, Y is at least one metal selected from Group 3 (including the Lanthanides and Actinides) and Group 6 of the Periodic Table of Elements and Z is at least one metal selected from Groups 7, 8, and 11 of the Periodic Table of Elements; m, n, p, and q are the atomic ratios of their respective components and, when m is 1, n is from about 0.01 to about 0.75, p is from 0 to about 0.1, and q is the number of oxygen atoms necessary to satisfy the valence of the other components, to form a crude dialkyl ether decomposition stream comprising alcohol and olefin; (d) recovering at least a portion of the olefin from the crude dialkyl ether decomposition stream; and (e) recycling at least a portion of the olefin recovered in step (d) to step (a).
    • 本发明涉及一种生产醇的方法,该方法包括(a)在足以形成包含醇和二烷基醚的粗醇物流的条件下,在催化剂存在下使烯烃和水反应; (b)将至少一部分粗醇流分离成含醇流和二烷基醚流; (c)使至少一部分二烷基醚料流与醚分解催化剂接触,所述醚分解催化剂包含具有以下组成的混合金属氧化物: 其中X是选自元素周期表第4族的至少一种金属,Y是选自第3族(包括镧系元素)中的至少一种金属 和锕系元素)和元素周期表第6族,Z是选自元素周期表第7,8和11族中的至少一种金属; m,n,p和q是它们各自成分的原子比,当m为1时,n为约0.01至约0.75,p为0至约0.1,q为必需的氧原子数 满足其他组分的化合价,形成包含醇和烯烃的粗二烷基醚分解物流; (d)从粗二烷基醚分解流中回收至少一部分烯烃; 和(e)将步骤(d)中回收的烯烃的至少一部分再循环到步骤(a)。
