The manufacturing method
of tert-amyl alcohol
tert-amyl alcohol is an important organic chemical raw material, which is widely used in medicine, pesticide, spice, solvent and other fields. The production method of tert-amyl alcohol will be described below.
1. Raw Material Preparation
The main raw materials for the manufacture of tert-amyl alcohol are isobutylene and formaldehyde. Among them, isobutylene can be prepared by petroleum cracking or natural gas, and formaldehyde can be prepared by methanol oxidation. In the process of raw material preparation, it is necessary to ensure the purity and quality of raw materials to avoid adverse effects on subsequent reactions.
2. reaction process
1. hydroformylation reaction
isobutylene and formaldehyde are mixed in a certain proportion, and a catalyst is added for hydroformylation reaction. The reaction is carried out at a certain temperature and pressure, and the reaction produces 3-methyl-3-butenal.
2. Hydrogenation Reaction
3-methyl -3-butenal is subjected to hydrogenation reaction, and a catalyst is added to generate tert-amyl alcohol. The hydrogenation reaction needs to be carried out at a certain temperature and pressure, and the flow rate of hydrogen and the reaction time need to be controlled to ensure the completeness of the reaction and the purity of the product.
3. product isolation and purification
After the reaction is complete, the product needs to be isolated and purified. First, the unreacted raw materials and by-products are separated by distillation, and then the tert-amyl alcohol product with high purity is obtained by distillation. In the process of separation and purification, it is necessary to select appropriate process conditions and equipment according to the quality and purity requirements of the product.
4. safety production and environmental protection requirements
In the manufacturing process of tert-amyl alcohol, it is necessary to pay attention to safety production and environmental protection requirements. First of all, it is necessary to ensure the sealing and safety of the equipment to prevent accidents such as leakage and fire. Secondly, it is necessary to strengthen the treatment and treatment of waste gas, waste water and solid waste to avoid harm to the environment and human health.
In short, the manufacturing method of tert-amyl alcohol needs to go through many steps and links, and it is necessary to pay attention to the preparation of raw materials, the control of the reaction process, the separation and purification of products, and the requirements of safe production and environmental protection, so as to ensure the quality and purity of the products, and at the same time ensure the safety and environmental protection of the production process.
