The manufacturing method
of furfuryl alcohol
1. Introduction

furfuryl alcohol is an important organic chemical raw material, widely used in synthetic resins, solvents, pharmaceuticals, pesticides and other fields. With the continuous development of science and technology, the manufacturing method of furfuryl alcohol has been continuously improved and optimized. This article will introduce the manufacturing method of furfuryl alcohol, including raw material preparation, reaction process, post-treatment and so on.

2. raw material preparation

furfuryl alcohol production raw materials are mainly furfural and methanol. Furfural is a colorless and transparent liquid with a special odor, which can be extracted from agricultural and sideline products such as rice husk and cottonseed hulls. Methanol is a common inorganic chemical raw materials, easy to obtain.

3. reaction process

furfuryl alcohol manufacturing process mainly includes the following steps:

1. Furfural mixed with methanol: the furfural and methanol in accordance with a certain proportion of mixing, stirring evenly.

2. Adding an acid catalyst: adding an appropriate amount of acid catalyst, such as sulfuric acid, hydrochloric acid, etc., to the mixture to promote the reaction.

3. Heating reaction: The mixture is heated to a certain temperature and kept for a certain period of time to make furfural and methanol react to generate furfuryl alcohol.

4. Cooling and separation: After the reaction was completed, the reaction solution was cooled to room temperature, and a mixture of furfuryl alcohol and methanol was separated.

4. post-treatment

1. distillation purification: the mixture of furfuryl alcohol and methanol is distilled to separate the pure furfuryl alcohol.

2. Neutralization: Use lye to neutralize the residual acid catalyst to make it meet the environmental emission standards.

3. Product packaging: Pure furfuryl alcohol is packaged for easy transportation and storage.

5. precautions

1. Control the quality and proportion of raw materials to ensure the smooth progress of the reaction and the quality of the product.

2. Strictly control the reaction temperature and time to prevent the occurrence of side reactions and the decomposition of the product.

3. Pay attention to the tightness and corrosion resistance of the equipment to ensure production safety and product quality.

6. conclusion The manufacturing method of

furfuryl alcohol involves many links and precautions, and it is necessary to strictly control the quality of raw materials, reaction conditions and post-treatment process to ensure product quality and production safety. At the same time, with the continuous progress of science and technology and the continuous improvement of environmental protection requirements, the manufacturing method of furfuryl alcohol will continue to update and improve, and make greater contributions to the development of the field of chemical production.
