Research Report of China's industry of oxalic acid, 2009

Oxalic acid is an important organic raw material base, mainly used to produce drugs such as antibiotics, synthetic borneol, pharmaceutical intermediates, extracts of precipitation of metals rare earth, rust dyeing, tanning agents, metal cleaners, etc. with the application teams expansion of oxalate in the synthesis of pharmaceuticals and pesticides, oxalate demands for increased steadily over the past years. Currently, demand volumes of oxalate in the world is near 400 thousand tons. In 2008, yields of oxalic acid in China exceeds 200 thousand tons and the volume of exports were about 50 thousand tons.

The traditional methods of industrialized production of oxalic acid mainly sodium completion of the format, oxidation, process oxo process of oxidation of glycol, propylene oxidation process, carbon monoxide, etc. coupling process Today, the manufacturing process Oxalic acid is through the chemical route for coal and the costs are low. The main mechanism lies in the later period, parts of hydrolyzed products intermediate generates dibutyl oxalate oxalic acid and methanol. Methanol can be used to produce the methyl ester of nitrous acid, which is used to produce dimethyl oxalate to achieve the objectives of cyclical utilization. During the pairing process, when the production of 1 ton glycol, oxalic acid 2 tons is produced at the same time.

Oxalic acid is mainly used to produce tetracycline, aureomycin and terramycin, etc. in the pharmaceutical industry. The development of these pharmaceutical products is highly dependent on export trends. With the development of the pharmaceutical industry China is expected that demands for oxalic acid in China's pharmaceutical industry will increase gradually.

Another important use Oxalic acid is the fusion of the rare earths. According to statistics, the smelting of rare earth needs 1.4 tons per ton of oxalic acid. In 2008, the demands for oxalic acid in China's rare earth industry were more than 100 thousand tons.

Currently, the largest manufacturer Oxalic acid in China is Yuanping Chemicals Co., Ltd, with annual output capacity of 70 thousand tons. In 2008, their actual returns exceeded 40 000 tonnes. The other domestic manufacturers are small scale and low concentration. The traditional method of industrialization of the production of oxalic acid has to use sulfuric acid and lead, which causes a serious threat to the environment.

Beyond Chemicals Co. Jinmei Tongliao, capable of producing oxalic acid synthesis carbonyl Ltd nitrate, other manufacturers generally adopt the process of carbohydrate oxidation of nitric acid, glycol oxidation of mixed acids and propylene oxidation of nitric acid, etc process also sodium formate additive process, comparatively contaminated environment, has been replaced in the world.

Tongliao Jinmei chemical Co., Ltd plans to build coal projects glycol made with the annual yield of 1.2 million tonnes. It is anticipated that a total investment of 10 billion yuan (1.43 billion dollars) and draft plans to be completed in three periods: the total amount of investment in the first period is 2 billion yuan (280 million dollars) for the construction of glycol project of 150 thousand tons and 40 thousand tons-project of oxalic acid. It is expected that the first-stage project will be completed in August 2009 and can produce 60,000 tons of glycol and oxalic acid 40 thousand tons in 2009, which will produce 150 thousand tons glycol and oxalic acid 100 thousand tons in 2010; the second period project is expected glycol 400 thousand tons to begin in mid March 2010 and be completed in late September 2010.

After the oxalic acid project Tongliao Jinmei Chemicals Co., Ltd in operation, is expected to hit hard on the current Chinese market of oxalic acid. Many oxalic acid medium and small manufacturers is replaced by the cost and environmental protection. On occasion, it is likely to reduce the price of oxalic acid fast that mass is constant small increase after withdrawing from the market.

Financial institutions international crisis that erupted in the second half of 2008, had affected China's exports of oxalic acid. Yuanping Chemicals Co., Ltd, the largest manufacturer National oxalic acid, had closed the regular general oxalic acid production lines due to the lack of order and moved to participate in research and production of oxalic acid used in the electronics industry and rare earth.

Compared with other chemicals, Oxalic acid price fluctuates slightly with the influence of international financial crisis. At the beginning of 2008, the bid price of 99.6% oxalic acid of Yuanping Chemicals Co., Ltd was 5,500 yuan (786 dollars) per tonne, rising to 7,000 yuan (1,000 dollars) per ton and again later reduced to 5,000 yuan (714 dollars) per ton and 5,500 yuan (800 dollars) per ton in early 2009.
