Manufacturing methods
of tert-butyl acrylate
tert-butyl acrylate (TBA) is an important organic chemical raw material, which is widely used in polymer synthesis, coatings, adhesives, textile treatment and other fields. This paper introduces the manufacturing method of tert-butyl acrylate in detail, including raw material preparation, reaction process, post-treatment and product quality control.

1. raw material preparation

1. Acrylic acid: Acrylic acid is the main raw material for the production of tert-butyl acrylate. Acrylic acid with higher purity should be selected to ensure product quality.
2. Tert-butyl alcohol: As another raw material for the esterification reaction, tert-butyl alcohol also needs to ensure high purity.
3. Catalyst: Sulfuric acid is usually selected as a catalyst to promote the esterification reaction.

2. reaction process

1. Pretreatment: Acrylic acid and tert-butyl alcohol are added to the reactor in a certain proportion, and the catalyst sulfuric acid is added at the same time.
2. Heating reaction: start stirring, gradually increase the temperature of the reactor, and keep the esterification reaction in the range of 60-80 ℃.
3. Dehydration: During the reaction process, water will be generated, which needs to be discharged in time through the water separator to promote the reaction to the direction of producing tert-butyl acrylate.
4. Post-treatment: When the reaction proceeds to a certain extent, the heating is stopped and the reaction solution is cooled to room temperature.

3. post-treatment and product quality control

1. Neutralization and washing: alkaline absorbent is added to the reaction solution to react with residual sulfuric acid, and then washed to remove impurities in the reaction solution.
2. Distillation: tert-butyl acrylate is separated from unreacted acrylic acid and tert-butyl alcohol by distillation to obtain tert-butyl acrylate with higher purity.
3. Quality inspection: quality inspection of the production of tert-butyl acrylate, including purity, acid value, color and other indicators to ensure that the product meets the relevant standards.

4. safety production and environmental protection requirements

1. safety production: in the production process, should strictly abide by the safety operation procedures, to ensure the normal operation of equipment, to prevent accidents.
2. Environmental protection requirements: The waste water, waste gas and other pollutants generated in the production process should be treated and discharged after meeting environmental protection standards to reduce the impact on the environment.

5. Suggestions for optimizing the production process

1. Improve the purity of raw materials: The use of high-purity raw materials is conducive to improving the product quality and yield of tert-butyl acrylate.
2. Catalyst selection: Other types of catalysts can be tried to improve the reaction rate and selectivity.
3. Optimize process parameters: Improve production efficiency and product quality by adjusting process parameters such as reaction temperature and reaction time.
4. Strengthen equipment maintenance: regularly inspect and maintain production equipment to ensure normal operation of equipment and reduce failure rate.

In short, the manufacturing method of tert-butyl acrylate involves many links and factors, in order to ensure product quality and production efficiency, it is necessary to strictly control the quality of raw materials, optimize the reaction process, strengthen post-processing and product quality control. At the same time, pay attention to safety production and environmental protection requirements, and promote the development of chemical production in a green and efficient direction.
