Archived from the original on 2017-07-27. p.622: Piria mentions "Hydrure de salicyle" (hydrogen salicylate, i.e., salicylic acid). Commercial vendors prepare sodium salicylate by treating sodium phenolate (the sodium salt of phenol) with carbon dioxide at high pressure (100 atm) and high temperature (115 °C)– a method known as the Kolbe-Schmitt reaction. Acidifying the product with sulfuric acid gives salicylic acid:

The aspirin should be analyzed forthe presence ofany contaminating salicylic acid. In the final part of today’s lab, you will take a small amount of your aspirin and test it withiron(III) chloride (FeCl 3).FeCl 3reacts with phenols(alcohol groups attached to aromatic rings)to produce colored complexes. Notice that salicylic acid contains the phenol functional group but aspirin does not. Therefore, the more salicylic acidthat contaminatesyour aspirin,the darker the color will bewithFeCl 3. The chosen recrystallization solvent will dissolve the compound when hot, but not at room temperature. If no crystals form, try: 1) scratching the inside of the flask with a glass rod at the interface of the solution or 2) concentrating your solution by boiling off some solvent. You may have too much solvent, i.e., your solution is not saturated, or 3) try the two-solvent recrystallization method.Buchanan WW, Kean WF (June 2002). "The Treatment of Acute Rheumatism by Salicin, by T.J. Maclagan — The Lancet, 1876". The Journal of Rheumatology. 29 (6): 1321–1323. PMID 12064852. In practice you purify by slowly cooling a hot, saturated solution of your compound. While cooling, molecules of the same type align in a crystal lattice, forming crystals. After cooling, crystals are collected by vacuum filtration and washed by rinsing with ice-cold solvent. At the laboratory scale, it can also be prepared by the hydrolysis of aspirin (acetylsalicylic acid) [25] or methyl salicylate (oil of wintergreen) with a strong acid or base; these reactions reverse those chemicals' commercial syntheses.

No. You need to cool the solution first to room temperature before placing it in the ice-water bath. Besides reducing the risk of breaking your flask and loosing your product in the ice-water, you will get better and purer crystals if you let the solution cool slowly. Hemel PB, Chiltoskey MU (1975).

SAFETY

Put at least 60 mL oflaboratorywater into a 150mL beaker (or similar size). Then put this beaker in an ice-water bath. Use this cold water in steps9,12,13,and14below. Main article: Medical uses of salicylic acid Cotton pads soaked in salicylic acid can be used to chemically exfoliate skin.

Acne treatment: A study published in the Journal of Drugs in Dermatology found that salicylic acid is an effective treatment for acne, helping to unclog pores, reduce inflammation, and prevent future breakouts.Salicylic acid is biosynthesized from the amino acid phenylalanine. In Arabidopsis thaliana it can also be synthesized via a phenylalanine - independent pathway. If none of the solvents tested is suitable for the single-solvent method, use the two-solvent method for recrystallization. In most cases, the single-solvent method is the recrystallization method of choice.
