标题:Process for preparation of benzophenone, anthraquinone and O-dibenzoylbenzene
发明人：FIELDS ELLIS K
权利人:STANDARD OIL CO INDIANA
摘要:Process for the concurrent synthesis of benzophenone, anthraquinone, and o-dibenzoylbenzene by pyrolysis of benzoic acid salts of yttrium, erbium, and dysprosium and mixtures thereof at temperatures of from about 200 DEG C. to 500 DEG C. and a pressure of about 0.1 to about 100 atmospheres. In an alternative method, a benzoic acid compound is passed through an oxide of yttrium, erbium, dysprosium and mixtures thereof in the presence of steam.

标题:Nucleophilic displacement method for synthesis of non-rigid PBZ polymers
发明人：INBASEKARAN MUTHIAH N; MULLINS MICHAEL J
权利人:DOW CHEMICAL CO
摘要:Azole rings, such as oxazole and thiazole rings, can activate an aromatic ring bonded to a leaving group such as a halogen atom so that the aromatic ring will undergo aromatic nucleophilic substitution. The reaction is useful for making ethers, thioethers and amines containing azole rings. In particular, monomers having azole rings, activated aromatic rings with leaving groups and nucleophilic moieties can react under conditions of aromatic nucleophilic displacement to form non-rigid rob PBZ polymers. The non-rigid rod PBZ polymers can be used to form molecular composites with rigid rod PBZ polymers which molecular composites are not substantially phase separated.

摘要:Described herein are PEKK polymers having improved processability and improved crystallinity. It was surprisingly found that PEKK polymers formed using a specifically adapted nucleophilic synthesis route, in which different monomers are added to the polymerization reaction at different points during the synthesis, had lower glass transition temperatures ('Tg') and increased crystallinities, relative to PEKK polymers formed using traditional nucleophilic synthesis routes ('traditional PEKK polymers'). Furthermore, compared with PEKK polymers synthesized using an electrophilic synthesis routes, the PEKK polymers described herein and significantly lower halogen content. The synthesis routes includes a first heating of a first monomer blend in a reaction mixture, a subsequent first addition of a second monomer blend to the reaction mixture, and a second heating of the reaction mixture subsequent to the first addition.
