Beschreibung
Ethyl 2-hydroxdybenzoate is also known as Ethyl salicylate, which a kind of ester formed through the condensation between salicylic acid and ethanol. It can be used as a perfumery, artificial essence flavoring agent and used in cosmetics. It can also be used as analgesics, anti-inflammatory and antipyretic agents.
Chemische Eigenschaften
clear colourless to pale yellow liquid
Occurrence
Reported found in raspberry, tomato, currants, rum, whiskey, red wine, plum brandy, Cape gooseberry, Feijoa
fruit, papaya and scotch.
Verwenden
manufacture of artificial perfumes.
synthetische
By esterification of salicylic acid with ethyl alcohol and concentrated H2SO4 at 100°C in the presence of aluminum sulfate; by heating to the boil an alkaline solution of salicylic acid and ethyl p-toluenesulfonate.
Vorbereitung Methode
Ethyl salicylate is found naturally in currants and strawberries
. It is manufactured commercially by the esterification
of salicylic acid with ethyl alcohol.
Allgemeine Beschreibung
Ethyl salicylate was hydrolysed to salicylic acid by the use of an extractive electrospray ionisation (EESI) device.
