Glycine Is Entering A Golden Age
This year, the domestic market by soaring glyphosate price
, as of December prices have risen to 58,000 yuan / ton, compared with the average price in 2006 rose 100%. With genetically modified herbicide-tolerant crops, bio-energy, high-speed development, and the world's largest manufacturer of glyphosate on glyphosate in the U.S. Monsanto to abandon expansion inputs, greatly broadened the glyphosate market, but also off of the intermediate glycine market.
Glycine is an important amino acid, widely used in pesticides, chemical, medical, pharmaceutical, feed and other fields. In China, glycine produced in the 20th century, only about 80 years, most relying on chlor-alkali plants and in order to extend product chlorine chloroacetic acid as the main raw material, production is limited. With the advent of glyphosate herbicide has been applied glycine in the pesticide industry to grow rapidly. Currently 80% of glycine for the production of glyphosate, glyphosate not only makes China became the largest exporting countries laid the foundation, but also making China the largest volume of world exports of glycine producer.
Glycine for the synthesis of glyphosate is the most widely used high-performance, low-residue, broad-spectrum herbicides. Glycine, as the largest pesticide intermediates, mainly two kinds of production process: chloroacetic acid glycine system of routes and route Diethanolamine (IDA method). Solution of chloroacetic acid in our ammonia process production of glycine is widely used technology, method has been applied glyphosate produced approximately 70% of total output. Glycine existing production equipment from abroad, the use of process route and on the preparation of glycine patent-pending technology to analyze the number and content, mainly in order to hydrocyanic acid, hydroxy-acetonitrile as raw materials Strecker process and Hydantion process.
From the supply side, the current global production capacity of glycine is about 23 million tons, concentrated in the industrial countries and regions, mainly the United States, Chatterton utility companies, the French Sipaxiya company, the Netherlands, Akzo Chemical Company, Japan's organic synthetic drugs, Corporation and Showa Denko Corporation. Glycine producers in China there are about 20 more than at present, due to cost and environmental factors, the supply of glycine have just over 10 million ton / year, and most of them are industrial-grade products, food grade and pharmaceutical grade glycine mainly rely on imports.
Because glycine in pesticide, feed, food, medicine, daily chemical industry, as well as the extensive use of the downstream industry chain, the constant expansion and extension of the global market demand, domestic market demand is growing faster. Only from the pesticide demands, according to incomplete statistics, China's glyphosate production are currently about 32 million tons, which means that nearly 230,000 tons of glyphosate production with glycine route.
A glyphosate production enterprise, Zhejiang head of the department, he said that producing 1 tonne of glyphosate need to use about 700 kilograms of glycine intermediate. Based on projections, in 2007 China needs to glycine (only pesticides) 16 million tons. While the domestic supply of glycine in 10 million tons per year, and the gap much. Although the system chloroacetic acid glycine route through the many years of domestic enterprises and, through the optimization of the production process conditions, the use of advanced large-scale equipment and DCS automatic control, product yield, rising raw material consumption, etc., the production costs can be reduced, methyl chloride and other by-products there was a marked improvement of the utilization, production has been released, but the lack of price of goods relative to glyphosate liters of state, you still can not meet the demand.
2008 is a crucial year for the release of glyphosate production. This year, China's glyphosate production capacity under construction in 10 million metric tons, the total expected to exceed 40 million tons, consumption of glycine is expected to more than 20 million tons. By 2010, the glycine consumption of about 49 million tons. Glycine development of the industry is entering a golden age. At present, the domestic market, the price of industrial grade glycine 1.9 yuan / tons. An industry source said that this price there is still much room for improvement.
