The gap of p-aminophenol is large

China has become the world's largest producer of antipyretics and analgesics. The output of aspirin, paracetamol, analgin and other varieties exceeds 10000 tons, while that of phenacetin, aminopyrine, antipyrine and other varieties exceeds 1000 tons. At present, the output of antipyretics and analgesics in China is growing rapidly, and it is expected to grow at a rate of about 8% in the future. The production of intermediates for antipyretic and analgesic drugs is large, and there are many manufacturers. With the increase of antipyretics and analgesics, the intermediates have made great progress.

In 2003, the consumption of paracetamol in China increased rapidly, and the export also showed a rapid growth momentum. The export volume was 28163 tons, with a year-on-year growth rate of about one time. In the first half of 2004, although its export growth slowed down, it still increased. From January to May 2004, the export volume of paracetamol was 12501 tons, slightly higher than that of the same period last year. P-aminophenol is an important intermediate in the synthesis of paracetamol, which has been growing rapidly in recent years. At present, the annual output of p-aminophenol in China is about 32000 tons. It is estimated that by 2005, the domestic output of paracetamol will reach more than 50000 tons, and the pharmaceutical industry will consume 45000 tons of p-aminophenol. Combined with the application in other fields, the total demand of p-aminophenol in 2005 is about 50000 tons, with a large market gap and a broad prospect of development and utilization.
