A process for hydrogenating mixed ethers after separation from hydrocarbon mixture to saturate the unsaturated ether(s) formed from the diolefins present in the hydrocarbon mixture. This may be applied to a process for separating C⁴ to C⁷ tertiary mono-olefins(s) present in a C⁴ to C⁷ hydrocarbon mixture containing diolefins which comprises selectively reacting said tertiary mono-olefin mixture with a primary alcohol in the presence of an acid catalyst to convert it to tertiary ether(s), separating the tertiary ether(s) from the unreacted hydrocarbon mixture and containing said tertiary ether(s) in the presence of a catalyst to decompose it to tertiary olefin(s) and a primary alcohol.
一种从碳氢化合物混合物中分离出混合醚后对其进行氢化的工艺,以饱和碳氢化合物混合物中存在的二烯烃形成的不饱和醚。该工艺可用于分离含有二烯烃的 C ⁴ 至 C ⁷ 碳氢化合物混合物中的 C ⁴ 至 C ⁷ 三级单烯烃,该工艺包括在酸催化剂存在下,使所述三级单烯烃混合物与伯醇发生选择性反应,将其转化为三级醚、将叔醚从未曾反应的碳氢化合物混合物中分离出来,并将所述叔醚在催化剂存在下分解成叔烯烃和伯醇。
