The manufacturing method
of methyl acrylate
1. Introduction

Methyl acrylate is an important organic chemical raw material, widely used in coatings, adhesives, fibers, plastics and other fields. With the continuous development of science and technology, the manufacturing method of methyl acrylate is also constantly improved and optimized. This article will introduce the manufacturing method of methyl acrylate, including raw material preparation, reaction process, post-treatment and other steps.

2. Raw Material Preparation

The production of methyl acrylate requires the preparation of the following raw materials: acrylic acid, methanol, and a catalyst. Among them, acrylic acid is the main reactant, methanol is the alcoholate, and the role of the catalyst is to accelerate the reaction rate. In order to ensure the smooth progress of the reaction, the quality control and allocation of raw materials are needed.

3. reaction process

The production of methyl acrylate mainly adopts the method of esterification reaction. The specific steps are as follows:

1. Acrylic acid and methanol are added to the reactor according to a certain ratio, and the catalyst is added at the same time.
2. The esterification reaction is carried out at a certain temperature and pressure. This process requires control of the reaction rate and temperature to ensure the progress of the reaction and the quality of the product.
3. After completion of the reaction, distillation separation was performed to obtain crude methyl acrylate.

4. post-treatment

post-treatment is an essential step in the manufacturing process of methyl acrylate, which mainly includes the following aspects:

1. Distillation and purification: The crude methyl acrylate is distilled and purified to remove impurities and water to obtain high-purity methyl acrylate products.
2. Waste liquid treatment: The waste liquid produced in the reaction process is treated to avoid environmental pollution.
3. Equipment cleaning: clean the reactor and related equipment to ensure the smooth progress of the next reaction.
Precautions for
5.

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

1. Strictly control the quality and proportion of raw materials to ensure the smooth progress of the reaction.
2. Control the reaction temperature and pressure to avoid side reactions and equipment damage.
3. carry out regular maintenance and overhaul of the equipment to ensure the normal operation of the equipment and the quality of the products.
4. Strengthen waste liquid treatment and environmental protection management to reduce environmental pollution.

6. Conclusion The manufacturing method of

methyl acrylate includes the steps of raw material preparation, reaction process and post-treatment. In the manufacturing process, it is necessary to strictly control the quality and proportion of raw materials, reaction temperature and pressure and other factors to ensure product quality and output. At the same time, it is also essential to strengthen waste liquid treatment and environmental protection management. By continuously optimizing manufacturing methods and strengthening production management, the manufacturing efficiency and product quality of methyl acrylate can be further improved, which contributes to the development of the chemical production field.
