9H-fluorene

Introduction:

Alias: 9H-fluorene is the fluorene, also called Diphenylenemethane; 2,2'-Methylenebiphenyl; 2,3-Benzindene; o-Biphenylenemethane; alpha-Diphenylenemethane-9H-fluorene; 2,2’-Methylemebiphemyl; alpha-diphenylenemethane; diphenylene-methan; Methane, diphenylene-; o-Biphenylmethane.

Although 9H-fluorene is obtained from coal tar, it can also be prepared by dehydrogenation of diphenylmethane. Alternatively, it can be prepared by the reduction of fluorenone with zinc. 9h-fluorene can be used for manufacture of dyestuff, medicines, and other organic synthesis chemical products.

Physical and chemical properties:

This product has a molecular weight of 166.22, a boiling point of 297.9 ° C, a melting point of 115 ° C and a density (20 ° C) of 1.181 g / cm3. White flaky crystals, easily sublimated in a high vacuum, insoluble in water, slightly soluble in ethanol, soluble in benzene, carbon disulfide, soluble in ether and glacial acetic acid. Fluorene can be used in the preparation of pharmaceuticals, synthetic resins, dyes and various auxiliaries and can also be used to produce detergents, wetting agents, liquid glitters, pesticides and photographic materials.

Features:

1) 9H-fluorene is weakly acidic.

2) 9H-fluorene is insoluble in water, soluble in organic agent, very soluble in high vacuum.

3) 9H-fluorene is easy to sublimate in high vacuum environment.

Package

The package of all our chemical products reaching up to the industry standard, we usually use kraft drums or woven bags for our powder state products.

Application: 

9H-fluorene 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.
