Jiande Dayang Chemical Co.,Ltd. is a high-tech enterprise in Zhejiang Provice, Located in Hangzhou City in the Yangtze delta that enjoys advanced economic development. Founded in 1976,presently we have assets of nearly RMB 200,000,000 yuan and cover an area of 300 sq km. Moreover ,we have such subsidiaries as Jiyuan Dayang Chemical Co.,Ltd., Hangzhou Dayang Nanometer Technology Co.,Ltd., Shanghai Taiyang Chemical Co.,Ltd., Jiande Dahua Thermal Power Co.,Ltd., Inorganic Branch Factory, Organic Branch Factory, Power Branch Factory and Dayang Chemical High-Tech Research&Development Center. Hence, our company is a group-type enterprise, which has been comprehensive engaged in manufacture , scientific research, development and trade.

Our company is one of the biggest manufactures of potassium carbonate in the world ,and will have realized the manufacturing capacity of over 100,000 tons by 2005. We enjoy complete product specifications and excellent quality ,thus our products having been well favored by customers at home and abroad. For dozens of years, according to the sampling tests of the State Testing Center for Inorganic Salt Quality, the qualified rates of all our products have reached 100%. We have paid much attention to technological innovation and established close cooperative relations with various famous domestic institutions of higher learning as well as research institutes with our capabilities in technological progress and technological innovation elevated. Accordingly, We have been able to manufacture potassium carbonate with the new process of“low-temperature self-carbonation of ion exchange”that has been developed by our company independently, thereby having improved the product quality and lowered the manufacturing cost. The relevant developing project wad listed into the 2003’s State Torch Plan Program. Moreover, we have successfully developed the comprehensive-utilization system for wastewater from potassium carbonate manufacture , and have reclaimed industrial-grade and agricultural-grade ammonium chlorides as sideline products, being the first to have realized the zero drainage of the industrial wastewater in the domestic potassium carbonate trade. Besides, we have successively developed 20-odd varieties of fine chemical products in the florin-containing product series, with the main ones of 2-chloro-6-fluorobenzaldehyde, 2-chloro-6-fluorobenzyl chloride, p-fluorobenzaldehyde etc., and also have developed nanometer-grade titanium dioxide, tertiary-butylhydroxyquinone, isodiether, succinic etc.

We are willing to closely cooperate with domestic and foreign friends from all circles, achieving successes in the future.
