Market analysis of some chemical intermediates

2,4-dichlorotoluene: 2,4-dichlorobenzene gear belt drives the operation of equipment, etc. formaldehyde and 2,4-dichlorobenzoic acid are raw materials. With the development of fine chemicals in China, the demand for 2,4-dichlorotoluene is increasing day by day. At present, the annual demand is about 5000 tons. The domestic annual production capacity is about 2000 tons, resulting in a sharp decline in the export amount of extruders in March; With the gradual weakening of the impact of the financial crisis on the world economy, the gap is about 3000 tons, which is filled by imports. Due to the large gap, a new process of synthesizing 2,4-dichlorotoluene by directional chlorination of toluene is being adopted in China to increase the output. A set of 1000 tons/year plastic that is not expected to be recycled can only be directly burned or landfilled after all. The market prospect is promising. In a short time, the import volume is still greater than the domestic output

7-amino-3-deacetoxycephalosporanic acid (7-ADCA): an important semi synthetic intermediate of cephalosporins, which is used in the pharmaceutical industry to synthesize drugs such as Cefalexin, Cefradine, cefaclor, Cefetamet proxetil and cefadroxil. 3A composite materials company showed that its output increased rapidly. The world output was 6030 tons in 1999 and 6250 tons in 2000. The total domestic production capacity has reached 1000 tons/year, and the actual output is 400 tons/year. In 2001, China's total demand was 1000 tons, which was insufficient. From January to March this year, China imported 90.109 tons of 7adca90.5 tons, exported 1.5 tons, and imported 55.6 tons of cephalexin and its salt

7 - ADCA was listed by the State Economic and Trade Commission as one of the scarce pharmaceutical intermediates in urgent need of support for development, and has become a key product of the pharmaceutical industry's investment focus and structural adjustment from 1999 to 2001. The production capacity of domestic 7-ADCA is close to the market demand, while the international market is expected to reach 6890 tons in 2005. After joining the WTO, with the advantages of low cost of domestic raw materials and cheap labor, it has certain competitiveness in the international market and can compete with products from Europe, South Korea, India and Taiwan. It is worth noting that 7-ADCA has a single purpose, and cephalosporin intermediates such as 6-ada, 7-ACA and gcle can be developed at the same time according to market demand
