权利人:XEROX CORP
摘要:Methods are provided for preparing aromatic silicon-containing compounds. The methods include providing an aromatic starting material; reacting the aromatic starting material with a base to form an aromatic salt; and reacting the aromatic salt with a halo-alkylene-silane to form an aromatic silicon-containing compound. Compositions prepared by these methods, protective layers that include hydrolysis and condensation products of such compositions, electrophotographic photoreceptors that include such protective layers, and image forming apparatuses that include such electrophotographic photoreceptors are also provided. In addition, method for preparing electrophotographic photoreceptors that include protective layers including hydrolysis and condensation products of aromatic silicon-containing compounds prepared by the methods for preparing aromatic silicon-containing compounds are provided.

发明人：MURPHY LEANNE DAWN
权利人:XEROX CORP
摘要:Processes for selectively hydrogenating double and/or triple bonds in organic molecules include providing at least one organic molecule containing a double and/or triple bond, providing at least one hydrogen donor molecule, and hydrogenating the double and/or triple bond in the presence of at least one catalyst. Processes for preparing arylamine molecules include selectively hydrogenating double bonds in arylamine compounds by providing at least one organic molecule containing a multiple bond, providing at least one hydrogen donor molecule, and hydrogenating the multiple bond in the presence of at least one catalyst. The processes provide efficient, cost-effective and safe methods for conducting selective hydrogenation reactions in the synthesis of organic molecules, such as charge-transport molecules.

标题:Stabilizer against hydrolysis for an ester-group-containing resin and a thermoplastic resin composition
发明人：TAKAHASHI IKUO; IIDA HIROTAKA; YANAGISAWA KEN-ICHI
权利人:NISSHIN SPINNING
摘要:A stabilizer against hydrolysis, which can solve conventional problems of a carbodiimide compound compounded in an ester-group-containing resin or a biodegradable plastic as a stabilizer against hydrolysis, such as poor heat resistance and a coloring problem due to yellowing, and can provide enhanced resistance against hydrolysis, and a thermoplastic resin composition of an ester-group-containing resin or a biodegradable plastic containing the same. Specifically, that the stabilizer against hydrolysis includes a carbodiimide composition comprising an aliphatic carbodiimide compound (A) and a phosphorus antioxidant (B), preferably the stabilizer contains a carbodiimide composition wherein a phosphorus antioxidant (B 1 ) is dispersed and present in the carbodiimide composition by admixing the phosphorus antioxidant (B 1 ) during synthesis of the aliphatic carbodiimide compound (A), and a thermoplastic resin composition having a superior stability against hydrolysis, characterized in that said stabilizer against hydrolysis is compounded in an easily hydrolysable resin (C).

摘要:Continuous and batch processes for selectively hydrogenating double and/or triple bonds in organic molecules include providing at least one organic molecule containing a double and/or triple bond, providing at least one hydrogen donor molecule, and hydrogenating the double and/or triple bond in the presence of at least one catalyst. Continuous and batch processes for preparing arylamine molecules include selectively hydrogenating double bonds in arylamine compounds by providing at least one organic molecule containing a multiple bond, providing at least one hydrogen donor molecule, and hydrogenating the multiple bond in the presence of at least one catalyst. The continuous and batch processes provide efficient, cost-effective and safe methods for conducting selective hydrogenation reactions in the synthesis of organic molecules, such as charge-transport molecules.

摘要:A carbodiimide composition having an improved heat resistance which meets conventional requirements for a carbodiimide compound to be compounded in an ester-group-containing resin or a biodegradable plastic, and exhibiting no coloring problems due to yellowing, and having a superior stabilizing effect agains hydrolysis. The carbodiimide composition comprises a carbodiimide compound (A) and an antioxidant (B), having a 5% weight loss temperature not lower than 250° C. as determined by a thermogravimetric (TG) method, wherein an antioxidant (B) is dispersed and present in the composition by admixing during synthesis of a carbodiimide compound (A), a stabilizer against hydrolysis mainly comprising the carbodiimide composition and a thermoplastic resin composition containing the same.
