Anisole, or methoxybenzene, is an organic compound with the formula CH 3 OC 6 H 5. It is a colorless liquid with a smell reminiscent of anise seed, and in fact many of its derivatives are found in natural and artificial fragrances .
Its chemical names are based on considering the structure as either an acetyl (methyl-ketone) analog of anisole. Other names It can also be seen as a methyl ether analog of acetophenone. Acetanisole is found naturally in castoreum, the glandular secretion of the beaver. [1]
Anisole (C 6 H 5 OCH 3) is the simplest phenol ether, and is a versatile precursor for perfumes and pharmaceuticals. [1] Vanillin and ethylvanillin are phenol ether derivatives commonly utilized in vanilla flavorings and fragrances, while diphenyl ether is commonly used as a synthetic geranium fragrance.
Lawesson's reagent is commercially available. It can also be conveniently prepared in the laboratory by heating a mixture of anisole with phosphorus pentasulfide until the mixture is clear and no more hydrogen sulfide is formed, [2] then recrystallized from toluene or xylene. Samples give a strong odor of hydrogen sulfide owing to partial ...
Trinitroanisole was first prepared in 1849 by the French chemist Auguste Cahours by reacting p-anisic acid (French: acide anisique) with a mixture of sulfuric acid and fuming nitric acid. [ 3 ] [ 4 ] Trinitroanisole can be prepared by the reaction of 2,4-dinitrochlorobenzene with methanol in the presence of sodium hydroxide followed by the ...
