Acrylic acid is a versatile chemical compound that has become an essential ingredient in a wide range of industries, from adhesives and coatings to superabsorbent polymers and personal care products. As the world’s second-largest producer of acrylic acid, China has played a significant role in shaping the global acrylic acid market. This article delves into the intricacies of China’s acrylic acid industry, exploring its production capacity, market dynamics, manufacturing processes, and the various applications of this important chemical.
Acrylic acid, also known as 2-propenoic acid, is a colorless, crystalline organic compound with the chemical formula CH₂=CHCO₂H. It is a highly reactive carboxylic acid that is widely used in the production of various polymers, esters, and other chemical intermediates.
China’s acrylic acid industry has experienced significant growth in recent years, with the country’s production capacity steadily increasing. According to industry reports, China’s acrylic acid production capacity reached 3.8 million metric tons in 2020, accounting for approximately 35% of the global production capacity.
The demand for acrylic acid in China has been driven by the country’s rapidly expanding industries, such as superabsorbent polymers, paints and coatings, and adhesives. The table below outlines the key market segments and their respective shares in China’s acrylic acid consumption:
| Segment | Market Share (%) |
|---|---|
| Superabsorbent Polymers | 40% |
| Paints and Coatings | 20% |
| Adhesives and Sealants | 15% |
| Textile Auxiliaries | 10% |
| Other Applications | 15% |
The Chinese acrylic acid market is dominated by several large-scale producers, including:
These companies have invested heavily in expanding their production capacities and improving their technological capabilities to meet the growing demand for acrylic acid in China and globally.
The primary method for producing acrylic acid in China is the propylene oxidation process. This two-step process involves the oxidation of propylene to acrolein, followed by the oxidation of acrolein to acrylic acid.

The propylene oxidation process requires the use of specific catalysts and precise reaction conditions to optimize the yield and purity of the acrylic acid produced. Commonly used catalysts include molybdenum-based and vanadium-based catalysts, which are often combined with other metal oxides to enhance their performance.
Acrylic acid is a key raw material in the production of superabsorbent polymers (SAPs), which are widely used in personal care products, such as diapers, feminine hygiene products, and adult incontinence products.
Acrylic acid and its derivatives are used in the formulation of water-based paints and coatings, providing improved adhesion, durability, and weather resistance.
Acrylic acid-based polymers and copolymers are used in the production of pressure-sensitive adhesives, construction adhesives, and sealants.
Acrylic acid and its esters are employed as textile auxiliaries, such as binders, thickeners, and finishing agents, in the textile industry.
Acrylic acid also finds applications in the production of plastics, detergents, cosmetics, and as a chemical intermediate for the synthesis of other compounds.
The production of acrylic acid can result in the generation of various environmental pollutants, such as volatile organic compounds (VOCs) and wastewater. Stringent environmental regulations in China have driven manufacturers to adopt cleaner production technologies and implement effective waste management strategies.
Ongoing research and development efforts are focused on improving the efficiency and sustainability of acrylic acid production, including the exploration of alternative feedstocks, such as renewable biomass, and the development of more advanced catalysts and reaction processes.
The prices of key raw materials, such as propylene, can be volatile, which can impact the overall production costs and profitability of the acrylic acid industry in China.
China’s acrylic acid industry has emerged as a global powerhouse, driven by the country’s rapidly growing demand for this versatile chemical. The industry’s impressive production capacity, coupled with the diverse applications of acrylic acid, underscores its strategic importance in supporting the development of numerous downstream industries. As the industry navigates challenges related to environmental concerns and raw material price fluctuations, the pursuit of technological advancements and sustainable production methods will be crucial in shaping the future of China’s acrylic acid market.
