Hippuric acid (Gr. hippos, horse, ouron, urine), benzoyl glycocoll or benzoyl amidoacetic acid, C₉H₉NO₃ or C₆H₅CO NHCH₂CO₂H, an organic acid found in the urine of horses and other herbivorae. Greek (Greek Ελληνικά, IPA – Hellenic) constitutes its own branch of the Indo-European languages. ... Urine is liquid waste excreted by the kidneys and eventually expelled from the body in a process known as urination. ... Binomial name Equus caballus Linnaeus, 1758 The Horse (Equus caballus) is a sizeable ungulate mammal, one of the seven modern species of the genus Equus. ...

It is excreted when many aromatic compounds, such as benzoic acid and toluene, are taken internally. Justus von Liebig in 1829 showed that it differed from benzoic acid, and in 1839 determined its constitution, while in 1873 Victor Dessaignes (Ann. 87, p. 325) synthesized it by acting with benzoyl chloride on zinc glycocollide. It is also formed by heating benzoic anhydride with glycocoll (Theodor Curtius, Ber., 1884, 17, p. 1662), and by heating benzamide with monochloracetic acid. Freiherr Justus von Liebig (May 12, 1803 in Darmstadt, Germany - April 18, 1873 in Munich, Germany) was a German chemist. ... Benzoyl chloride, also known as benzenecarbonyl chloride, is a colourless, fuming liquid, C6H5COCl, with an irritating odour. ...

It crystallizes in rhombic prisms which are readily soluble in hot water, melt at 187°C. and decompose at about 2400°C. It is readily hydrolysed by hot caustic alkalis to benzoic acid and glycocoll. Nitrous acid converts it into benzoyl glycollic acid, C₆H,CO.OCH₂CO₂H. Its ethyl ester reacts with hydrazine to form hippuryl hydrazine, C₆H₅CONHCH₂CONHNH₂, which was used by Curtius for the preparation of azoimide. For the battery, see alkaline battery The word alkali can mean:- In chemistry, an alkali is a specific type of base, formed as a carbonate, hydroxide or other ionic salt of an alkali metal or alkali earth metal element. ... Structural formula Benzoic acid, C6H5C(O)OH, is an aromatic carboxylic acid. ... Nitrous acid weak monobasic acid known only in solution and in the form of nitrite salts. ... Hydrazine is a chemical compound with formula N2H4 used as a rocket fuel. ... This article needs to be cleaned up to conform to a higher standard of quality. ...
