On acrylic acid

Acrylic acid is also an important chemical substance. Its characteristics are specific, it has a wide range of uses, and the production method is also exquisite.

First, the properties of acrylic acid
Acrylic acid, like a colorless liquid, has an irritating odor. When it boils, it is about one hundred and forty degrees Celsius, and when it melts, it is nearly zero degrees Celsius. This substance is soluble in water, ethanol, and ether solvents. It has active chemical properties and contains carbon-carbon double bonds. It is easy to cause addition and polymerization reactions. It can combine with many compounds to form new substances, laying the foundation for chemical synthesis.

Second, the application of acrylic acid
Acrylic acid is widely used in the field of industry and life. In the paint industry, acrylic paints made from this raw material have excellent weather resistance, chemical corrosion resistance and color stability. They are often applied to building exterior walls and automobile surfaces to keep them bright for a long time and resist wind and rain erosion. In the field of adhesives, acrylic adhesives are highly viscous, cure quickly, and have a wide range of applications. They can bond metals, plastics, wood and other materials. They are indispensable in the electronics and packaging industries. In the textile industry, acrylic-treated fabrics have anti-wrinkle, waterproof, anti-fouling and other characteristics to improve the quality and practicality of fabrics. In the papermaking, leather, oilfield and other industries, acrylic acid also plays an important role in helping the development of various industries.

Third, the production of acrylic acid
There are various methods for the production of acrylic acid. One is the propylene oxidation method, which uses propylene as raw material, and under specific catalyst and temperature and pressure conditions, acrylic acid is obtained through two-step oxidation reaction. This process is mature and has considerable output. It is the main production method today. The second is the ethylene carbonylation method, which uses ethylene, carbon monoxide and water as raw materials to synthesize acrylic acid through catalytic reaction. This method has high atomic utilization rate and environmental protection advantages. However, the technical requirements are also high. In addition, there are other production routes, each with its own advantages and disadvantages. Producers need to weigh their options according to the actual situation in order to achieve efficient, economical and environmentally friendly production purposes.

Acrylic acid, with its unique properties, has shown important value in many fields. With the progress of science and technology, its application and production technology will continue to innovate, contributing more to social development.
