HMA (Hydrogenated Methacrylate) is an important raw material for the production of chemicals and is widely used in adhesives, coatings, inks and other fields. A manufacturing method of HMA will be introduced below.
I. Preparation of raw materials
1. methyl methacrylate (MMA): purity ≥99.5%
2. hydrogen: purity ≥99.9%
3. catalyst: generally platinum catalyst
2. Preparation of equipment
1. high-pressure reactor: used to carry out the hydrogenation reaction
2. stirring device: used to ensure that the reaction proceeds uniformly
3. temperature control device: used to control the temperature of the reaction
4. pressure control device: used to control the reaction temperature
4.
4. Pressure control device: used to control the reaction pressure
3. Manufacturing steps
1. Add methyl methacrylate (MMA) into the high pressure reactor and maintain a certain temperature and pressure.
2. Start the hydrogenation reaction by introducing hydrogen gas and adding catalyst at the same time.
3. Control the reaction temperature and pressure, and maintain a certain reaction time, so that the reaction is fully carried out.
4. After the reaction, carry out post-processing, including cooling, separation, purification and other steps, to obtain pure HMA products.
4. Precautions
1. The selection and use of catalyst should be carried out in strict accordance with relevant regulations and operational requirements to ensure safety and catalytic effect.
2. The control of reaction temperature and pressure should be precise to avoid side reactions and safety accidents.
3. The purity and quality of the products should be paid attention to in the post-treatment process to ensure the use performance of the products.
In conclusion, the manufacture of HMA requires strict control of conditions in all aspects such as raw materials, equipment and manufacturing process to ensure the quality and safety of the products. Meanwhile, the manufacturing process should meet the relevant requirements of environmental protection and safe production to promote the sustainable development of the chemical industry.
