Determination of the Thermal Diffusivity of Calcium Salts of Saturated Carboxylic Acids1
(International Journal of Thermophysics, 2013-01-16)
Functionalized cobalt clusters. Properties of carboxylate clusters (CO)6Co2HCC-COOH and (CO)10Co 4HCC-COOH as related to their structures
(Elsevier S.A., 2002)
Reaction of propiolic acid (HCCCOOH) with dicobalt octacarbonyl (Co 2(CO)8) and tetracobalt dodecacarbonyl (Co 4(CO)12) leads to the organometallic carboxylic acids (CO)6Co2HCC-COOH (1) and (CO)10Co 4HCC-COOH (2) in good ...
Synthesis and X-ray diffraction study of calcium salts of some carboxylic acidsa
(Powder Diffraction, 2013-01-16)
Microwave Assisted Synthesis of ethyl-quinolon-4-one-3-carboxylates and Hydrolysis to quinolon-4-one-3-carboxylic Acids
(Bentham Science Publishers, 2014-05)
A fast and efficient microwave assisted synthesis of several ethyl-quinolon-4-one-3-carboxylates and quinolon- 4-one-3-carboxylic acids has been developed. The 3-carboethoxy quinolones are easily obtained in a one-pot ...
Practical synthesis of a functionalized 1-oxo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The synthesis of a functionalized 1-oxo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid has been performed in 10 steps from the readily available dimedone. Only three purifications by flash chromatography are required ...
Study of the reaction mechanism of the transesterification of triglycerides catalyzed by zinc carboxylates
(Elsevier Science, 2013-06)
In this theoretical and experimental study, the mechanisms for the transesterification of triglycerides catalyzed by zinc carboxylates were analyzed and discussed. Different alternatives were examined: (A) the classic Lewis ...
Partitioning of Carboxylic Acid Between Oil and Water Phases: Experimental, Correlation, and Prediction
Partition coefficients for the carboxylic acids (A) acetic and formic acids between oil and water were measured, correlated, and predicted. The experiments were conducted by equilibrating the systems, soybean oil (SO)– ...
Intraspecific variability of dihydrochalcone, chromenes and benzoic acid derivatives in leaves of Piper aduncum L. (Piperaceae)
Chemical analysis carried out in leaves of 18 specimens of Piper aduncum L. (Piperaceae) occurring at Ripasa Reserve, Araraquara, SP, Brazil indicated two distinct populations when investigated over a period of 14 months ...
