I. Raw materials
The following raw materials are mainly used in the manufacture of isobutyric acid:
1. Carbon tetrahydrocarbon mixture: Carbon tetrahydrocarbon mixture is the main raw material of isobutyric acid, which contains isobutylene, n-butylene and other components.
2. Oxygen: Oxygen is used as an oxidizing agent to oxidize the olefins in the carbon tetrahydrocarbon mixture into carboxylic acid.
2. Process flow
The manufacturing process of isobutyric acid mainly includes the following steps:
1. Mixing of raw materials: the mixture of carbon tetra-hydrocarbons and oxygen are mixed according to a certain proportion, and enter into the oxidation reactor.
2. Oxidation reaction: In the oxidation reactor, the mixture undergoes oxidation reaction in the presence of a catalyst to produce isobutyric acid.
3. Separation of products: The reaction products are cooled and separated to give isobutyric acid and unreacted raw material.
4. Refining and purification: The product of isobutyric acid with high purity is obtained by refining and purification.
3. Operation steps
1. Checking equipment: check whether the oxidation reactor, cooler, separator and other equipment are in normal operation to ensure the safety of the production process.
2. Feeding operation: Put the carbon 4 hydrocarbon mixture and oxygen into the oxidation reactor according to a certain proportion, and control the reaction temperature and pressure.
3. Reaction control: The catalyst is added and adjusted according to the reaction conditions to keep the reaction stable. Cooling and separation of products: The products are cooled down to a certain temperature and separated into gas and liquid to obtain isobutyric acid and unreacted raw materials.
5. Refining and purification: The isobutyric acid is refined and purified to obtain a high purity product.
4. Equipment selection
In the manufacturing process of isobutyric acid, the equipment to be used includes oxidation reactor, cooler, separator, refining and purifying equipment, etc.. When selecting equipment, it is necessary to make comprehensive consideration according to the production scale, product quality requirements, safety and environmental protection and other factors, and select the equipment with stable performance, easy operation, safety and reliability.
