This year, the completion and operation of a 30,000-ton-per-year glyoxal production plant by Shanghai Huayi Group Shangsu Vulcanization Co., Ltd. has intensified the issue of overcapacity in China's glyoxal market. Despite the growing production capacity, the domestic product quality remains relatively low, and the application areas are still concentrated, leading to increasing challenges in managing excess supply. To address this, it is essential for the industry to enhance technological capabilities and broaden the range of applications.
In 2006, China consumed approximately 45,000 tons of glyoxal. The majority—46.7%—was used in the pharmaceutical industry, followed by textile printing and dyeing (22.2%), light industry (24.4%), and smaller shares in the oil industry (4.4%) and other sectors (2.3%). By 2010, total demand is projected to reach around 57,000 tons, with the same three main industries continuing to dominate consumption.
The light industry sector, particularly the paper industry, accounted for about 11,000 tons of glyoxal use in 2006. As China's economy grows and consumer demands for higher-quality products increase, this sector is expected to see steady growth, reaching around 13,000 tons by 2010.
Textile printing and dyeing is another key application area. In 2006, it consumed roughly 10,000 tons, and with the global shift of the dye industry towards China, demand is expected to rise to about 12,000 tons by 2010.
Glyoxylic acid, a derivative of glyoxal, is an important intermediate in organic synthesis. With the rapid development of the pharmaceutical industry, the demand for pharmaceutical-grade glyoxal has been rising. In 2006, the consumption was around 21,000 tons, and it is anticipated to reach 27,000 tons by 2010.
In the oil industry, glyoxal is mainly used in pipeline lubricants, primarily by large-scale oil fields. The 2006 consumption was approximately 20,000 tons, and this is expected to grow to around 30,000 tons by 2010.
The overcapacity problem has become more evident as many manufacturers have expanded or built new facilities due to the attractive market prospects. Currently, there are nearly 10 producers in China, with a total annual production capacity of about 100,000 tons and actual output of around 55,000 tons. Major companies include Shanghai Huayi Group Shangsu Vulcanization (58,000 tons/year), Hubei Hengri Chemical (10,000 tons/year), and others. With new plants coming online, such as Hubei Luotian Shunhui’s 20,000-ton facility, total capacity is expected to reach 120,000 tons by 2010, while demand will only be around 57,000 tons. This imbalance suggests that new projects should be approached with caution.
To resolve the crisis, manufacturers need to focus on improving product quality, especially in reducing formaldehyde content, and controlling costs. Additionally, the acetaldehyde method offers better quality and broader applications, and domestic R&D efforts should focus on solving environmental issues like wastewater and exhaust emissions, while improving yield and process efficiency.
Currently, most glyoxal is used in textile, pharmaceutical, and paper industries, which have high quality requirements. To expand the market, the industry should promote applications in construction, oil extraction, coatings, water treatment, leather tanning, cement additives, and other sectors where lower-quality glyoxal is acceptable.
Finally, expanding exports is crucial. While countries like the U.S., Japan, and Germany produce large quantities for domestic use, many in Russia, Australia, and Southeast Asia still rely on imports. Chinese producers should target international markets, improve product quality, and work toward sustainable and healthy industry growth.
