Description
Technical field
The utility model relates to the chemical industry equipment field, particularly relates to a kind of Fu Ke acyl chloride reaction device.
Background technology
Friedel-crafts acylation is to do under the catalyst condition at strong lewis acid, allows acyl chlorides and phenyl ring carry out the reaction of acidylate.This reaction can also use carboxylic acid anhydrides as acylating reagent, and reaction condition is similar to the condition of alkylated reaction and removes.The first step is under lewis acidic condition, and dissociating of chlorine forms the acyl group carbonium ion: second step was ensuing aromatic ring electrophilic reagent attack acyl cation: final step, electric charge are transferred to the chlorine atom and form HCl, and AlCl
3Catalyst forms again.Generating the acyl group carbonium ion as can be known by reaction expression is reversible reaction.In present actual production process; generally judge by dropping time, reaction temperature and the duration of control acyl chlorides whether reaction finishes; this deterministic process human factor accounts for leading; do not monitor in real time at reaction simultaneously; can't intuitively find out the process of reaction; error in judgement and result have a long way to go, and cause the friedel-crafts acylation yield low.Simultaneously, in the friedel-crafts acylation process since in the hydrogen chloride gas phase because gas-liquid equilibrium, can carry a part of recoverable material secretly and escape.
