The manufacturing method
of cinnamophenol
cinnamophenol, also known as 3-phenylpropofol, is an important organic compound widely used in the field of chemical production raw materials. It has unique fragrance and antibacterial properties, so it is often used in food additives, cosmetics and pharmaceuticals. This article will detail the manufacturing method of cinnamol.

1. Raw Material Preparation

The production of cinnamol requires the preparation of the following raw materials: phenol, acetone, sodium hydroxide. Among them, phenol and acetone can be purchased through the market, and sodium hydroxide can be purchased through chemical raw material stores.

2. reaction process

The production of cinnamol is mainly achieved by the condensation reaction of phenol and acetone under alkaline conditions. The specific steps are as follows:

1. phenol is mixed with sodium hydroxide solution and heated to a molten state.
2. Acetone was added slowly while maintaining the basic environment of the reaction system.
3. at a certain temperature, the reaction for a period of time, the formation of cinnamon phenol sodium salt.
4. Adjust the pH to neutral or acidic with acid to convert cinnamophenol sodium salt to cinnamophenol.
5. Separate cinnamol from the reaction system by distillation or extraction.

3. post-treatment
The cinnamol produced by
needs to be post-treated, including washing, drying, purification and other steps, in order to obtain high-purity cinnamol products.

4. Precautions

1. During the entire manufacturing process, it is necessary to keep the temperature and pH of the reaction system stable to ensure the smooth progress of the reaction.
2. Because cinnamol has certain toxicity, it is necessary to pay attention to safety and avoid direct contact during operation.
3. In the post-processing process, it is necessary to pay attention to the purity and yield of the product to ensure the quality and yield of the product.

In short, the manufacturing method of cinnamol is not complicated, but it is necessary to pay attention to the reaction conditions and post-treatment process to ensure the quality and yield of the product. At the same time, because cinnamol has a certain toxicity, it is necessary to pay attention to safety during operation to avoid harm to the human body.
