Sodium salicylate circulates in the blood unchanged, decomposition occurring in the kidney, and probably in tissues suffering from the of Poynton and Paine. It used to be stated that these drugs are marked cardiac depressants; and the heart being invariably implicated in rheumatic fever, it is supposed that these drugs must be given with great caution. It has now been established that, provided the kidneys be healthy, natural salicylic acid, sodium salicylate prepared from the natural acid, and salicin, are not cardiac depressants. Of the two latter, 300 grains may be given in a dose and i 2 oz. in twenty-four hours, without any toxic symptoms. The artificial acid and its salt contain ortho-, paraand meta-cresotic acids, which are cardiac depressants. The vegetable product - which is extremely expensive - must be prescribed or the synthetic product guaranteed "physiologically pure," tested upon animals and found to have no toxic properties. Salicylates are the next safest to quinine of all antipyretics, whilst being much more powerful in all febrile states except malaria. Sodium salicylate escapes from the blood mainly by the kidneys, in the secretion of which sodium salicylate and salicyluric acid can be detected within fifteen minutes of its administration. After large doses haematuria has been observed in a few cases. The rapid excretion by the kidneys is one of the cardinal conditions of safety, and also necessitates the very frequent administration of the drug.

They are derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol.
Experiment 7: Synthesis of Ester Methyl Salicylate
Esters, whether artificial or natural, are wide used flavorings and perfumes.
used, in high concentrations, as a rubefacient and analgesic in deep heating liniments (such as Bengay) to treat joint and muscular pain
used, in low concentrations (0.04% and under), as a flavoring agent in chewing gum and mints
used as a simulant or surrogate for the research of chemical warfare agent sulfur mustard, due to its similar chemical and physical properties
used as an antiseptic in Listerine mouthwash produced by the Johnson & Johnson company.
Most instances of human toxicity due to methyl salicylate are a result of over-application of topical analgesics, especially involving children.

ESTERIFICATION OF SALICYLIC ACID USING Ce 4 + MODIFIED ..

SALICYLIC ACID (ortho-hydroxybenzoic acid), an aromatic acid, C 6 H 4 (OH)(CO 2 H), found in the free state in the buds of and, as its methyl ester, in gaultheria oil and in the essential oil of It was discovered in 1838 by Piria as a decomposition product of salicin. It may be obtained by the oxidation of saligenin and of salicylic aldehyde; by the distillation of copper benzoate; by the decomposition of anthranilic acid with nitrous acid; by fusion of ortho-chlor or ortho-brom benzoic acid with potash; by heating orthocyanphenol with alcoholic potash; by heating a mixture of phenol, carbon tetrachloride and alcoholic potash to 100° C. (F. Tiemann and K. Reimer, 1876, 9, p. 1285); and by the action of sodium on a mixture of phenol and chlorcarbonic ester (T. Wilm and G. Wischin, 1868, 6).
