(oil of wintergreen).4 Part 2: Synthesis of Methyl Salicylate.

(Rosmarinus Officinalis)
A sharp fresh green fragrance, originally from France, Spain and Portugal, this aromatic shrubby perennial bush has silver green leaves sky blue flowers, the oil is steam distilled from the flowers. A great oil for stimulating and clearing the mind, a reviving and refreshing oil.

Essential oils are also effectively used at home in different ways, both for their medicinal and cosmetic qualities. They are used as perfumes for potpourris, sometimes added to beauty preparations, or used in simple baths. They are known to be good for the scalp and skin care, and some oils even have a healing effect on the body. Essential oils can be even used in minor first aid treatment or to help relieve colds, headaches, aching muscles or period pains.

Wintergreen Oil, Synthetic | Spectrum Chemical

2 reactions carried out:
H2SO4 – catalyzed
H3PO4 – catalyzed (less strong, less potentially harmful)
Micro-scale reaction – less waste
Extraction with diethyl ether (instead of methylene chloride) – less toxic Reflux-condensation setup: synthesis of wintergreen oil Salicylic acid, methanol, sulfuric/phosphoric acid
Stirred in hot water bath, while cooling steam with water current, for 60 minutes
Removed from heat, cooled to ambient temperature Liquid-Liquid extraction: Diethyl ether and DI water added to reaction mixture, organic layer (bottom) extracted
Organic layer washed 3x with sodium bicarbonate (vented to release CO2 gas), extracted after last wash, and solvent (ether) boiled off
NMR spectra analyses performed on remaining product (1) (2) Hartel, A.M.; Hanna, J.M.
