2-Ethylbutanol (2-Ethylbutanol) is an important organic chemical material, widely used in solvents, plasticizers, spices, pharmaceutical intermediates and other fields. The following is a common manufacturing method of 2-Ethylbutanol:
I. Preparation of raw materials
The main raw materials for manufacturing 2-Ethylbutanol are ethylene, carbon monoxide and hydrogen. Among them, ethylene can be produced by methods such as petroleum cracking or ethanol dehydration, while carbon monoxide and hydrogen can be obtained by water gas reaction.
II. Synthesis reaction
1. Carbonyl synthesis: Ethylene, carbon monoxide and hydrogen are passed into the carbonyl synthesis reactor in a certain proportion, and the carbonyl synthesis reaction is carried out under the action of catalyst to produce butyraldehyde.
2. Hydroformylation: Butyraldehyde undergoes a hydroformylation reaction with carbon monoxide and hydrogen in the presence of a catalyst to produce 2-ethylbutyraldehyde.
3. Hydrogenation reaction: 2-Ethylbutyraldehyde undergoes hydrogenation reaction in the presence of catalyst to produce the target product 2-Ethylbutanol.
III. Product Separation and Purification
After the reaction, 2-ethylbutanol is separated from the reaction mixture by distillation, extraction and other separation techniques and purified to obtain a product with high purity.
The above is a common method for manufacturing 2-ethylbutanol, the specific production process needs to be optimized and adjusted according to the actual situation of the proportion of raw materials, reaction conditions, separation and purification methods and other parameters, in order to ensure the quality and yield of the product. At the same time, in order to ensure the safety and environmental protection of the production process, it is also necessary to carry out strict control and management of production equipment, waste gas and waste water treatment.
