The manufacturing method
of isononyl alcohol
isononyl alcohol is an important raw material for chemical production, which is widely used in coatings, inks, cleaning agents, plastic plasticizers and other fields. This article will introduce the manufacturing method of isononyl alcohol, including raw material preparation, reaction process, post-treatment and so on.

1. Raw Material Preparation
The production of
isononanol requires the preparation of the following raw materials: propylene, carbon monoxide, hydrogen. Among them, propylene is the main raw material, carbon monoxide and hydrogen are auxiliary raw materials.

2. reaction process

The manufacture of isononyl alcohol mainly adopts the carbonyl synthesis method, the specific steps are as follows:

1. Propylene hydroformylation reaction: after mixing propylene, carbon monoxide and hydrogen, under the action of high temperature, high pressure and catalyst, the hydroformylation reaction is carried out to generate propionaldehyde.

2. Propionaldehyde condensation reaction: the propionaldehyde in the acidic catalyst under the action of condensation reaction to generate isononal.

3. isononyl aldehyde hydrogenation reaction: isononyl aldehyde is hydrogenated to generate isononyl alcohol under the action of a catalyst.

In the above reaction process, the following control elements need to be paid attention to: reaction temperature, pressure, type and amount of catalyst, reaction time, etc. The control of these factors has an important impact on the quality indicators such as yield, purity and color of the product.

3. post-treatment
After the
reaction is completed, post-treatment is required, including distillation, extraction, rectification and other steps, in order to obtain a higher purity isononanol product. At the same time, the waste needs to be treated to avoid pollution to the environment.

4. precautions

In the manufacturing process of isononanol, the following matters need to be paid attention to:

1. Selection and use of catalysts: Different catalysts have different effects on the reaction, and need to be selected and used according to the actual situation.

2. Control of reaction temperature and pressure: The control of reaction temperature and pressure has an important impact on the progress of the reaction and the quality of the product, and needs to be adjusted according to the actual situation.

3. Waste disposal: Waste needs to be properly disposed of to avoid environmental pollution.

In short, the manufacture of isononanol requires mastering the corresponding technologies and methods, and at the same time, it is necessary to pay attention to safety, environmental protection and other issues to ensure product quality and smooth production.
