of the manufacturing method
of isopropanol Isopropanol is an important organic chemical raw material, which is widely used in medicine, cosmetics, coatings, solvents and other fields. This article will introduce the manufacturing method of isopropanol, including raw materials, process flow, operation steps, equipment selection and other related content.

1. Raw Material

The production of isopropanol mainly uses propylene, water and hydrogen as raw materials. Among them, propylene is the main raw material, and water and hydrogen are auxiliary raw materials.

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

1. Propylene hydration reaction: propylene reacts with water under the action of a catalyst to generate a mixture of isopropanol and acetone.

2. separation and purification: isopropyl alcohol and acetone are separated by distillation and other methods to obtain isopropyl alcohol products with high purity.

3. Catalyst regeneration: The used catalyst is regenerated for recycling.

3. Operation Steps

1. Propylene, water and hydrogen are mixed according to a certain ratio and then introduced into the reactor.

2. Under the action of catalyst, propylene reacts with water to form a mixture of isopropanol and acetone.

3. After the reaction, the mixture is cooled, separated and purified to obtain isopropanol with high purity.

4. Regenerate the used catalyst for the next use.

4. equipment selection

The manufacture of isopropanol requires the use of the following equipment:

1. Reactor: For the reaction of propylene and water, a reactor with good sealing performance and stirring equipment should be selected.

2. distillation column: for separation and purification of the mixture of isopropanol and acetone, should choose a distillation column with appropriate tray and tower height.

3. Catalyst regeneration device: For the regeneration of the catalyst, a device with heating and cooling functions should be selected.

5. safety and environmental protection requirements

In the manufacturing process of isopropyl alcohol, you need to pay attention to the following safety and environmental protection requirements:

1. Strictly control the quality and proportion of raw materials to ensure the smooth progress of the reaction.

2. Strengthen the maintenance and maintenance of equipment to prevent leakage and failure.

3. Properly dispose of waste and by-products to avoid harm to the environment and human body.

4. Strengthen staff safety training and environmental awareness, improve the level of safety production.

In short, the manufacture of isopropyl alcohol needs to be carried out in strict accordance with the process flow and operation steps, select appropriate equipment, and strengthen safety and environmental protection management to ensure product quality and production safety and environmental protection.
