Manufacturing method of tert-Amyl Alcohol
Tert-Amyl Alcohol is an important organic chemical raw material, which is widely used in the fields of pharmaceuticals, pesticides, spices, solvents and so on. The manufacturing method of tert-Amyl alcohol will be introduced below.
I. Preparation of raw materials
The main raw materials for manufacturing tertiary 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 method. In the process of raw material preparation, it is necessary to ensure the purity and quality of raw materials to avoid adverse effects on the subsequent reaction.
II. Reaction process
1. Aldolization reaction
Isobutylene and formaldehyde are mixed according to a certain ratio, and a catalyst is added to carry out the aldolization reaction. The reaction is carried out at a certain temperature and pressure, and the reaction produces 3-methyl-3-butenal.
2. Hydrogenation reaction
The 3-methyl-3-butenal is subjected to a hydrogenation reaction with the addition of a catalyst to produce tertiary amyl alcohol. The hydrogenation reaction needs to be carried out at a certain temperature and pressure, and the flow rate of hydrogen and reaction time need to be controlled to ensure the complete reaction and the purity of the product.
Three, product separation and purification
After the reaction is completed, the product needs to be separated and purified. Firstly, the unreacted raw materials and by-products are separated by distillation, and then the tertiary amyl alcohol product with higher purity is obtained by distillation. In the process of separation and purification, it is necessary to select suitable process conditions and equipment according to the quality and purity requirements of the product.
Four, safety production and environmental protection requirements
In the manufacturing process of tertiary amyl alcohol, it is necessary to pay attention to safety production and environmental protection requirements. Firstly, it is necessary to ensure the sealing and safety of the equipment to prevent the occurrence of accidents such as leakage and fire. Secondly, the treatment and disposal of waste gas, waste water and solid waste need to be strengthened to avoid harming the environment and human health.
In conclusion, the manufacturing method of tertiary amyl alcohol needs to go through a number of steps and links, and it is necessary to focus on the preparation of raw materials, the control of the reaction process, the separation and purification of the product as well as the safe production and environmental protection requirements, so as to ensure the quality and purity of the product, and at the same time, safeguard the safety of the production process and environmental protection.
