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]
Chromic acid oxidizes it to benzoic acid; zinc and acetic acid reduce it to cinnamic acid, C 6 H 5 CH=CHCO 2 H, whilst sodium amalgam reduces it to hydrocinnamic acid, C 6 H 5 CH 2 CH 2 CO 2 H. Ortho-nitrophenylpropiolic acid, NO 2 C 6 H 4 CCCO 2 H, prepared by the action of alcoholic potash on ortho-nitrocinnamic acid dibromide, crystallizes ...

The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
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 ...

In addition, the formation of carbon dioxide from decarboxylation reactions during hydrotreating can form carbonic acid when contacted with water. [19] Hydrogen Consumption - removing oxygen, cracking long-chain molecules, and saturating olefinic bonds will chemically consume two to four times the hydrogen of a conventional ULSD hydrotreater.
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.
