BENZOTHIAZOLE HAVING FLUORENE SKELETON AND METHOD FOR PRODUCING THE SAME
-
Paragraph 0057, (2017/01/09)
PROBLEM TO BE SOLVED: To provide a novel 2-mercaptobenzothiazole having a fluorene skeleton which can be used as the raw material for a polybenzothiazole having a fluorene skeleton, and a method for producing the same. SOLUTION: It is found out that the reaction between a bis-o-bromoaniline having a fluorene skeleton and a xanthic acid and/or an alkali metal salt of the xanthic acid makes it possible to produce a novel 2-mercaptobenzothiazole having a fluorene skeleton with good selectivity.

Chlorination process, alkylation of products of said process and some products thereof

, (2008/06/13)
Compounds having acidic protons and a molecular structure which can delocalize the electron density of the conjugate base (target compounds) are chlorinated by contacting such compounds with a perchloroalkane and aqueous base in the presence of a phase transfer catalyst which is an tetraalkylammonium hydroxide. Chlorinated products, preferably gem-dichloro compounds, are produced. The gem-dichloro compounds are useful for alkylation of aromatic compounds. For instance fluorene is chlorinated to form 9,9-dichlorofluorene which is reacted with such compounds as phenol or aniline to form such compounds as 9,9-bis(hydroxyphenyl)fluorene, 9,9-bis(aminophenyl)fluorene, or 9-aminophenyl-9-chlorofluorene.
Epoxy resin curing agent, curing process and composition containing it

, (2008/06/13)
Epoxy resin compositions which on curing yield cured resins having a high glass transition temperature, high ductility, and low moisture pick-up sed. To obtain such cured resins, 9,9--bis(aminophenyl)fluorenes are used as cured agents.
