Since 1993, The coke output of China has been ranked first in the world. In 2004, the coal tar output of China is about 7 million tons. As the main component of coal tar, the mass fraction of fluorene in coal tar is 1-2%. Therefore, China has abundant fluorene resources. At present, most manufacturers do not extract fluorene, only burn it as cheap fuel oil and carbon black raw material, which is a great waste of precious fluorene resources. Jinan Realong chemical Co., Ltd is committed to the extraction and development of fluorene, at the same time, deeply excavates the downstream products of fluorene to exaggerate the application field of fluorene and bring more considerable benefits.

Fluorene is a white flake crystal, stored in coal tar, melting point 116-117 degrees Celsius, boiling point 295 degrees Celsius, insoluble in water, soluble in carbon disulfide, ether, benzene, thermal ethanol.

In recent years, the preparation of high value-added chemicals around the deep processing of raw materials is a hot research topic, such as the preparation of 9-fluorenone, 9-oxime methanol, bisphenolphthalein, polyfluorene and so on. In particular, the German company Ludgege has been able to use our bismuth to produce 9-fluorenone, 9-nonanol, 9-anthracenecarboxylic acid, 9-indole acetic acid and other products.

Our aim is to provide stable and high quality products for domestic and foreign companies and scientific research institutions. Looking forward to cooperating with you.
