Microwave assisted one pot synthesis of 7-substituted 2-(2-oxo-2H-chromen-3-yl)acetic acids as precursors of new anti-tumour compounds

02-Aug-2010 | Silvia Kováčová, Lucia Kováčiková, Margita Lácová, Andrej Boháč, Marta Sališová, Chemical Papers, 2010

Perkin condensation with subsequent intramolecular lactonisation as one pot syntheses of 2-(2-oxo-2H-chromen-3-yl)acetic acids VIIa-Xa has been studied. The required acids VIIa-Xa were prepared as precursors of recently discovered compounds possessing antineoplastic activities. Syntheses of ...

Chain extension of adipic acid and (or) succinic acid/butanediol polyesters with 2,2′‐(1,4‐phenylene)‐bis(2‐oxazoline) and adipoylbiscaprolactamate combined chain extenders

30-Jul-2010 | Xu, Shao Yi; Shi, Yan Hong; Zhao, Jing Bo; Jiang, Sheng Ling; Yang, Wan Tai, Polymers for Advanced Technologies, 2010

Abstract This paper provided an easy and flexible method to synthesize high molecular weight polyesters by polycondensation and chain extension. Low molecular weight polybutylene adipate, polybutylene succinate, and poly(butylene succinate-co-butylene adipate) (PBSA) were synthesized through ...

Synthesis and electrochemical characterizations of nano size Ce doped LiMn2O4 cathode materials for rechargeable lithium batteries

07-Jul-2010 | D., Arumugam , G. Paruthimal, Kalaignan, Journal of Electroanalytical Chemistry, 2010

LiCexMn2-xO4 (x = 0.00 to 0.10) cathode materials for rechargeable lithium-ion batteries were synthesized by simple sol-gel technique using aqueous solutions of metal nitrates and succinic acid as the chelating agent. The gel precursors of metal succinates were dried in vacuum oven for 10 h at ...

Unsaturated, biobased polyesters and their cross‐linking via radical copolymerization

01-Jul-2010 | Jasinska, Lidia; Koning, Cor E., Journal of Polymer Science Part A: Polymer Chemistry, 2010

Biobased, unsaturated polyesters derived from isosorbide, maleic anhydride, and succinic acid were synthesized and characterized. The presence of maleic anhydride units in the structure of the polyesters allowed converting them into cured coatings by radical copolymerization with crosslinking ...

The Lewis Acid-Catalyzed Synthesis of Hyperbranched Oligo(glycerol–diacid)s in Aprotic Polar Media

29-Jun-2010 | Victor T. Wyatt, Gary D. Strahan, Alberto Nuñez, Journal of the American Oil Chemists' Society, 2010

The Lewis acid, titanium (IV) butoxide [15% (w/w; catalyst/reactants)], was used to catalyze the condensation of 0.05 mol glycerol with 0.10 mol of succinic acid, glutaric acid, and azelaic acid to produce oligomers. The reactions were refluxed in dilute solutions of dimethylsulfoxide (DMSO) or ...

(Co‐)Polyesters Derived from Isosorbide and 1,4‐Cyclohexane Dicarboxylic Acid and Succinic Acid

01-Jun-2010 | Garaleh, Mazen; Yashiro, Takao; Kricheldorf, Hans R.; Simon, Peter; Chatti, Saber, Macromolecular Chemistry and Physics, 2010

The homopolyester of isosorbide and cis-trans 1,4-cyclohexane dicarboxylic acid (CHDA) was prepared by three different methods, but only polycondensation of isosorbide and CHDA dichloride yielded a satisfactory molecular weight (corrected = 11 000 Da). For the best sample the MALDI-TOF mass ...

Aqueous-Phase Hydrogenation of Biomass-Based Succinic Acid to 1,4-Butanediol Over Supported Bimetallic Catalysts

28-May-2010 | Doan Pham Minh, Michèle Besson, Catherine Pinel, Patrick Fuertes, Carole Petitjean, Topics in Catalysis, 2010

The effect of addition of Re to activated carbon-supported Ru and Pd catalysts in the hydrogenation of 15 wt% succinic acid aqueous solutions to 1,4-butanediol (BDO) was examined. The yield and selectivity were in the range 62–66% at 160 °C and 150 bar over the Re promoted catalysts. Bio-succinic ...

Hydrogenation of Succinic Acid to γ-Butyrolactone over Palladium Catalyst Supported on Mesoporous Alumina Xerogel

20-May-2010 | Ung Gi Hong, Sunhwan Hwang, Jeong Gil Seo, Jongheop Yi, In Kyu Song, Catalysis Letters, 2010

Abstract Mesoporous alumina xerogel (AX) was prepared by a sol–gel method for use as a support for palladium catalyst. Palladium catalyst supported on mesoporous alumina xerogel (Pd/AX) was then prepared by an impregnation method. For comparison, commercial alumina (AC) was also used to prepare ...

Hygroscopic Properties of Internally Mixed Particles of Ammonium Sulfate and Succinic Acid Studied by Infrared Spectroscopy

20-May-2010 | Lorena Miñambres; María N. Sánchez; Fernando Castaño; Francisco J. Basterretxea; María ..., Journal of Physical Chemistry A, 2010

Atmospheric aerosols typically consist of inorganic and organic material. Although the organic fraction can affect the behavior of mixed organic/inorganic particles, their physical properties are not well-understood. In this work, infrared spectra of internally mixed submicrometer particles of ...
