Extraction Method:  

Methane, diphenylene- extraction methods are two methods of distillation and potassium melting:

(1) distillation method. The heavy oil wash including the anthracene oil front fraction was rectified by a distillation column of 60 trays, the fluorene fraction of 290-310 ° C was cut off, and the Methane, diphenylene- cut of 293-297 ° C was further fractionated by the Methane, diphenylene- fraction. The narrow fractions were cooled, crystallized and centrifuged to give crude Methane, diphenylene-. The crude Methane, diphenylene- was recrystallized from xylene-water mixed solvent to obtain industrial Methane, diphenylene- having a purity of about 95%.

(2) potassium melting method. Raw materials for the 290 ~ 310 ℃ fluorene fraction. The fluorene fraction was fractionated and cut into fluorene narrow fractions of 292 to 302 ° C. The fluorene narrow cut plus potassium hydroxide at 280 ~ 300 ℃ under the melting, hydrolysis, remove impurities to obtain crude fluorene. Recapitalization of crude fluorene, resulting 292 ~ 298 ° C fractions obtained by recrystallization of industrial fluorene. Fine fluorene from industrial fluorene, in addition to using xylene - water mi


Uses:

This product is an important organic synthesis of raw materials. Industrial fluorene polycyclic aromatic hydrocarbons is a coal tar, a wide range of uses, can be synthesized trinitrofluorenone, aromatic transparent nylon, Indanthrene, is an important organic synthesis of raw materials; can be used for the preparation of drugs, synthetic resins , Dyes and various additives, can also be used to produce detergents, wetting agents, liquid glitter, pesticides, photographic materials and liquid crystal compounds. For example, 9,9-bis- (2-carboxyethyl) fluorene can be used to prepare a polyimide resin, and 2-dialkyl aminoacetyl fluorenone can be used as an analgesic and antispasmodic agent, 9-fluorenone-2-carboxy Amino alcohol esters can be used as local anesthetics, 2-dialkyl aminomethyl fluorene antispasmodics, analgesics and antihypertensives, and 5-fluorenecarboxylic acid is a plant growth-stimulating hormone.
