The manufacturing method
of isopropenyl alcohol
isopropenyl alcohol, also known as 2-propen-1-ol, is an important organic chemical raw material, widely used in fine chemicals, pharmaceuticals, pesticides and other fields. This paper will introduce the manufacturing method of isoallyl alcohol, including raw materials, process flow, operation points and so on.

1. raw material

isopropenyl alcohol manufacturing raw material mainly has two kinds: propylene and synthesis gas (carbon monoxide and hydrogen). Among them, propylene is the main raw material, and synthesis gas is the auxiliary raw material.

2. Process
The manufacturing process of
isopropenyl alcohol mainly includes the following steps:

1. Propylene oxidation reaction

After mixing propylene and synthesis gas, it is introduced into an oxidation reactor to carry out oxidation reaction under the action of a catalyst to generate acrolein and acetone and other products.

2. Aldehyde and ketone hydrogenation reaction

The acrolein and acetone and other products generated in the oxidation reactor are introduced into the hydrogenation reactor, and the hydrogenation reaction is carried out under the action of the catalyst to generate isopropenyl alcohol.

3. product separation and purification

through distillation, extraction and other separation technology, isopropenyl alcohol is separated from the reaction mixture, and purified to obtain high purity isopropenyl alcohol products.

3. Operating Points

1. Control of Reaction Temperature

In the oxidation reaction and hydrogenation reaction process, it is necessary to control the appropriate reaction temperature to ensure the reaction and product selectivity.

2. Choosing the right catalyst

Choosing the right catalyst can increase the rate and selectivity of the reaction while prolonging the service life of the catalyst.

3. Controlling the ratio of raw materials

Reasonable control of the ratio of propylene and synthesis gas can ensure the smooth progress of the reaction and improve the yield of isopropenyl alcohol.

4. Strengthen equipment maintenance and management

Regular inspection and maintenance of equipment to maintain the normal operation of the equipment can reduce the failure rate and improve production efficiency.

4. safety production and environmental protection requirements

1. Strictly abide by safety production rules and regulations to ensure the safety of employees and equipment.

2. Strengthen the treatment of waste gas, waste water and other pollutants to achieve discharge standards and protect the environment.

5. Market Prospect and Application

With the rapid development of the domestic chemical industry, the market demand for isopropenyl alcohol is showing a growing trend. In the future, with the continuous progress of technology and the expansion of application fields, the market prospect of isoallyl alcohol will be broader. Its main application areas include:

1. fine chemicals: used in the production of various alcohols, ethers, esters and other fine chemicals.

2. pharmaceutical intermediates: intermediates for the synthesis of antibiotics, vitamins and other drugs.

3. pesticides: used in the production of pesticides, fungicides and other pesticide products.

In conclusion, isoallyl alcohol, as an important organic chemical raw material, has broad application prospects in the field of chemical production raw materials. By mastering its manufacturing methods and strengthening the research and improvement of production process, the production efficiency and quality of isoallyl alcohol can be improved, and it will make a positive contribution to the development of the domestic chemical industry.
