WebSep 4, 2016 · Due to their low reactivity toward nucliophile, the reaction usually occur at higher temperature. For example 1-chloro-4-nitrobenzene the reaction occur at high temperature., Nucleophilic substitution reaction probably occur through the slow addition of nucleophile to the ring, and second step fast removal of Cl group. WebSimilar to methanol, DME may directly be synthesized from synthesis gas, a mixture of H2 and CO. Direct synthesis of DME actually passes two reaction steps: methanol synthesis and followed by methanol dehydration. Based on the kinetics studies, the direct synthesis of DME is dictated by the dehydration of methanol to DME [1, 2]. Thus, a
