Abstract

The invention discloses a preparation process of iso-tridecanol, which comprises the following steps of: (1) treating a raw material by a raw material pretreatment unit to obtain a triisobutylene isomer mixed solution mainly containing alpha-triisobutylene and beta-triisobutylene; (2) carrying out hydroformylation reaction on the triisobutylene isomer mixed solution; (3) adding a complexing agent for complexing, and then carrying out phase splitting; (4) further separating an oil phase, enabling a tower kettle hydroformylation reaction liquid to enter a hydrogenation reaction unit, enabling a tower top component to be treated by a double-effect isomerization unit and then circularly enter a hydroformylation reaction unit, and enabling hydrogen generated by the double-effect isomerization unit to enter the hydrogenation reaction unit; and (5) separating and purifying the hydrogenation reaction product to obtain an iso-tridecanol product. According to the method, a hydroformylation reaction byproduct can be converted into alpha-TIB for preparing iso-tridecanol, the yield of iso-tridecanol is increased, the reaction yield is high, and side reactions are few.

Description

technical field [0001] The invention relates to the field of chemical preparation methods, in particular to a high-efficiency and energy-saving preparation process of isomeric tridecanol. Background technique [0002] Isomerized tridecyl alcohol is easy to disperse or dissolve in water, has excellent wettability, permeability and emulsification, and is widely used in the fields of textile industry, leather industry and metal processing. [0003] The basic raw materials for the synthesis of fatty alcohols include ethylene, kerosene and natural gas. The production processes mainly include hydroformylation and Ziegler processes, such as: Ziegler ethylene oligomerization and natural oil hydrogenation to produce branched chain fatty alcohols; Fischer-Tropsch synthesis Alkenes are hydroformylated to produce semi-branched alcohols; tributenes are hydroformylated to produce branched chain alcohols; aliphatic alcohols are condensed by guerbet reactions to produce Guerbet alcohols. ...
