Salicylic acid phenyl ester or phenyl salicylate is the phenyl ester of salicylic acid .
presentation
Phenyl salicylate can be prepared by reaction of Salicylsäurechlorid with phenol can be produced.
properties
Phenyl salicylate is a colorless, crystalline powder that has a slightly aromatic odor and is only very slightly soluble in water, but more soluble in benzene , chloroform , ethanol and ether .
The bromination of phenyl salicylate with elemental bromine in glacial acetic acid initially leads to the 5-bromo derivative. The 3,5-dibromo derivative is formed when 2 moles of bromine are used.
use
Phenyl salicylate has an antiseptic and anti-rheumatic effect and is also used as UV -protection for the skin and for plastics use. It was introduced into therapy in 1886 as Salol ® ; The main purpose was to disinfect the urinary tract .
