3. Chlorosulfonic acid use
First, mainly used in the manufacture of sulfonamides, as well as dye intermediates, sulfonating agents, dehydrating agents, plastics, pesticides and synthetic saccharin.
two. Production overview of chlorosulfonic acid in China
With the continuous development of China's chemical industry, the production of chlorosulfonic acid has increased rapidly. In 1990, the output was only 80.6kt. In 1999, it increased to 120.2kt. In 2005, it reached 194.5kt. In 2009, it was above 300kt. The products are mainly sold in China, and the export volume is small.
III. Overview of the consumption of chlorosulfonic acid in China
With the development of the dye industry and related industries, the demand for chlorosulfonic acid in the domestic market is increasing. In 1990, the consumption was 67,000 tons, in 1999 it was 115,000 tons, in 2005 it was 200,000 tons, and in 2009 it was 24- 280,000 tons, most of the chlorosulfonic acid produced in China is consumed by the domestic market, and the growth of consumption is basically the same as the output.
four. Analysis of the import and export of chlorosulfonic acid in China
Due to the characteristics of chlorosulfonic acid products, the import and export volume of this product is very small. In 2005, the export was about 15,000 tons. However, with the enhancement of the competitiveness of domestic chlorosulfonic acid production enterprises, exports are an inevitable trend for enterprises to maintain sustained growth.
Fives. Market analysis of chlorosulfonic acid
Since 2005-2007, the chlorosulfonic acid market has been relatively stable. However, after entering the off-season demand in the third quarter of 2007, prices in some regions have risen, and the market price is basically 2200-2550 yuan/t. Since 2008, the price of chlorosulfonic acid has basically stabilized at 2,700-3,000 yuan. In 2009, with the rise in prices, the price basically remained at 3,500-4,200 yuan / ton. Mainly because the raw material market price increase is large, sulfur and liquid chlorine prices are relatively high, this year (2010) has a 20%-30% increase. At present, most of the major domestic chlorosulfonic acid producers use imported sulfuric acid.
In addition, due to the fact that the production capacity of enterprises with chlorosulfonic acid production capacity below 10 kt/a in China is about 100 kt/a, most of the small enterprises producing chlorosulfonic acid will shut down, stop, and turn as the market competition becomes increasingly fierce. This provides a development space for enterprises with raw materials and technological advantages to build chlorosulfuric acid plants of 20kt/a or more.
six. Introduction of chlorosulfonic acid production enterprises in China
At present, there are about 10 manufacturers of chlorosulfonic acid in China. Among them, Shenyang Xinguang Chemical Factory is the largest manufacturer of chlorosulfonic acid in China. Shenyang Xinguang Chemical Factory (Group) has Shenyang No.5 Reagent Factory and Shenyang Trial Biochemical Technology. Development Co., Ltd. (formerly Shenyang Reagent No. 3 Factory) has a total annual production capacity of 40,000 tons; Shandong Liaocheng Luxi Chemical Third Chemical Fertilizer Plant has an annual production capacity of 20,000 tons (2008 data);
The output of chlorosulfonic acid of Shandong Huayan Pesticide Chemical Group is 10,000 tons/year; the annual output of Jiangsu Jiewei Chemical Industry Co., Ltd. is 20,000 tons/year. Shanghai Wusu Chemical Co., Ltd. is 15,000 tons/year, and Hebei Yinzhou Hongji Chemical Co., Ltd. has an annual output of 7,000 tons.
7. Introduction of high purity chlorosulfonic acid enterprise.
In terms of high-purity chlorosulfonic acid, Shenyang Xinguang Chemical Plant (Group) is the only company in China that can produce reagent grade chlorosulfonic acid, with an annual output of about 10,000 tons. The purity is 97-99%, and the sulfuric acid and other acrobatic content are controlled at 1-2%, which can meet the quality demand of high-purity chlorosulfonic acid in any domestic sulfonation enterprise. The purity is up to 99.9% or more, while other domestic chlorosulfonic acid enterprises are basically 95% industrial grade chlorosulfonic acid with more heavy metals.
Moreover
Shenyang No.5 Reagent Factory, Shenyang Xinguang Chemical Plant (13889302460), Shanghai Jiaoyu Chemical Co., Ltd., Tianjin Chemical Reagent Factory, Shanghai Huaxin Chemical Co., Ltd., Tianjin Chemical Industry Supply and Marketing Company, Wuxi Sulfuric Acid Plant 20,000 tons/year (2007 The annual production capacity is 20,000 tons/year, and the following companies are all in 2007).
Henan Open Source Chemical Group has 20,000 tons/year, Taiyuan Chemical Group Corporation has 20,000 tons/year, and Jilin Sifang United Chemical Co., Ltd. has 15,000 tons/year.
Eight. 2011 price forecast
Ordinary industrial chlorosulfonic acid due to the increase in prices and raw materials in 2010, the price will reach 10,000 yuan / ton in 2011, and
The price of refined chlorosulfonic acid is currently between 25,000 and 50,000 yuan/ton, depending on the difference in purity and heavy metals. In the past year or two, due to the shortage of market and price reasons, the price will rise slightly. It is expected that the price will reach 30,000 yuan or more in 2011. With the demand for fine chemical raw materials from China's sulfonation enterprises, refined chlorosulfonic acid (reagent grade) The demand will increase significantly, while the production capacity of ordinary industrial grade chlorosulfonic acid will be compressed.
