Acetic acid is the second simplest carboxylic acid (after formic acid ). It is an important chemical reagent and industrial chemical across various fields, used primarily in the production of cellulose acetate for photographic film, polyvinyl acetate for wood glue, and synthetic fibres and fabrics.
Evernic acid is an organic compound and depside with the molecular formula C 17 H 16 O 7. [2] Evernic acid was first isolated from the lichen Usnea longissima. [3] [4] Evernic acid is soluble in hot alcohol and bad soluble in water. [5] [6] [7] Evernic acid is produced by the lichens Ramalina, Evernia, and Hypogymnia.
Infobox references. Caproic acid, also known as hexanoic acid, is the carboxylic acid derived from hexane with the chemical formula CH3(CH2)4COOH. It is a colorless oily liquid with an odor that is fatty, cheesy, waxy, and like that of goats [1] or other barnyard animals. It is a fatty acid found naturally in various animal fats and oils, and ...
Adipic acid or hexanedioic acid is the organic compound with the formula (CH 2) 4 (COOH) 2.From an industrial perspective, it is the most important dicarboxylic acid: about 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon.
Indole-3-acetic acid ( IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1] IAA is a derivative of indole, containing a carboxymethyl substituent. It is a colorless solid that is soluble in polar organic ...
t. e. Constrained Application Protocol ( CoAP) is a specialized UDP-based Internet application protocol for constrained devices, as defined in RFC 7252. It enables those constrained devices called "nodes" to communicate with the wider Internet using similar protocols. CoAP is designed for use between devices on the same constrained network (e.g ...
Infobox references. Sebacic acid is a naturally occurring dicarboxylic acid with the chemical formula HO2C (CH2)8CO2H. It is a white flake or powdered solid. Sebaceus is Latin for tallow candle, sebum is Latin for tallow, and refers to its use in the manufacture of candles. Sebacic acid is a derivative of castor oil.
