Phenylpropanoic acid or hydrocinnamic acid is a carboxylic acid with the formula C 9 H 10 O 2 belonging to the class of phenylpropanoids. It is a white, crystalline solid with a sweet, floral scent at room temperature. Phenylpropanoic acid has a wide variety of uses including cosmetics, food additives, and pharmaceuticals. [5]
Phenylacetic, 3-phenylpropanoic and 3-phenylpropenoic acids are found in propolis, mammalian exocrine secretions or plant fragrances. During a systematic study of the lipids from seeds of the plant Araceae, [1] the presence of 13-phenyltridecanoic acid as a major component (5-16% of total fatty acids)was discovered. Other similar compounds but ...
Hydrogenation is a chemical reaction between molecular hydrogen (H 2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule ...
Tropic acid is a chemical with IUPAC name 3-hydroxy-2-phenylpropanoic acid and condensed structural formula HOCH 2 CHPhCOOH. It is a laboratory reagent used in the chemical synthesis of atropine and hyoscyamine. Tropic acid is a chiral substance, existing as either a racemic mixture or as a single enantiomer.
Phenylpropiolic acid, C 6 H 5 CCCO 2 H, formed by the action of alcoholic potash on cinnamic acid dibromide, C 6 H 5 CHBrCHBrCO 2 H, crystallizes in long needles or prisms which melt at 136–137 °C. When heated with water to 120 °C, it yields phenylacetylene (C 6 H 5 CCH).
The water thread experiment is a phenomenon that occurs when two containers of deionized water, placed on an insulator, are connected by a thread, then a high-voltage positive electric charge is applied to one container, and a negative charge to the other. At a critical voltage, an unsupported water liquid bridge is formed between the ...
In addition, the volume of each experiment is independent of that of the volume of the flow tube thereby saving a significant amount of reactant per experiment. When performing reaction screening and libraries, segment composition is typically varied by the composition of matter. When performing reaction optimization, segments vary by ...
In chemistry, the hydrogenation of carbon–nitrogen double bonds is the addition of the elements of dihydrogen (H 2) across a carbon–nitrogen double bond, forming amines or amine derivatives. [1] Although a variety of general methods have been developed for the enantioselective hydrogenation of ketones, [ 2 ] methods for the hydrogenation of ...
