Disturbances of acid-base equilibrium in salicylate intoxication.
The uricosuric activity of phenylbutazone, probenecide and sulphinpyrazone is strongly antagonized by salicylate and maybe completely diminished by small doses due to decreased tubular reabsorption of uric acid (Insel, 1996).
The loss of buffering capacity and the effects of salicylate on carbohydrate, lipid and protein metabolism lead to the development of a metabolic acidosis or, more commonly in practice, a mixed acid-base disturbance (Proudfoot & Brown, 1969; Meredith & Vale, 1981; Proudfoot, 1983).

Preparation of Phenol from Salicylic Acid - …
Salicylic acid may cause excessive drying and irritation in some people (Parish, 1991).
Free College Essay Synthesis of Salicylic Acid from Wintergreen Oil
Metabolic pathways of salicylic acid become saturated and thus plasma concentration increases, producing toxicity.
(vinyl alcohol)-Salicylic Acid Conjugate: Synthesis and ..
However, in severe salicylate poisoning in adults, metabolic acidosis may also occur.
Salicylic acid (PIM 642) - INCHEM
The dyes industry was also in the forefront in asserting intellectual property rights. Favorable patent laws play important roles in the pharmaceutical and life science industries; witness the recent scramble to patent human genes. However, they did not benefit aspirin. Bayer settled for registering a trademark for the name Aspirin. It did not patent acetylsalicylic acid, not because it would not but because it could not. The chemical was old stuff, synthesized by French chemist Charles Frederic Gerhardt back in 1853.

Salicylic acid is also used in the form of paint and in the form of collodion basis (10 to 17%) or as a plaster (20 to 50%) to destroy warts and corns.
Benzoic acid - New World Encyclopedia
In patients with significant acidosis and in patients who ingest multiple doses or sustained release preparations, the Done nomogram will tend to underestimate the severity of salicylate intoxication (Todd et al., 1981).
Benzoic acid was discovered in the 16th century
He also synthesized Aspirin because his father, who had severe arthritis, could not tolerate the salicylic acid he was taking for pain relief.
The Kolbe Synthesis for the production of salicylic acid was created by the German chemist Hermann Kolbe.
Topical Agents Used in the Management of Hyperpigmentation
Further Analysis THE END Presented by MY LIFE: YOU LIGHT IT UP Conclusion The overall objectives of this experiment were to synthesize aspirin, to perform a crude purity test on said aspirin, to standardize and prepare solutions of both NaOH and HCL, and to qualitatively determine the purity of the aspirin by finding the percentage of acetylsalicylic acid in the aspirin.
