Identity

Florantone T is a name for 6-acetyltetralin. Other names for it include 5,6,7,8-tetrahydro-2-acetonaphthone and 5,6,7,8-tetrahydronaphth-2-yl methyl ketone. Its formula is C₁₂H₁₄O, and its structure is written CC(=O)C1=CC2=C(CCCC2)C=C1, an acetyl group on the aromatic ring of a tetrahydronaphthalene.

Properties

Its evaporation rate is very slow. It carries an irritant safety label. Its boiling point is estimated at 287 °C and its flash point at 119.07 °C. Its XLogP3-AA is 3.0, and its pKa is estimated at 8.01, that of a weak base.

Parent hydrocarbon

Tetralin, or 1,2,3,4-tetrahydronaphthalene, is a hydrocarbon of formula C₁₀H₁₂ and a partially hydrogenated derivative of naphthalene.

Uses and storage

Florantone T serves as a fragrance ingredient and as a chemical intermediate, for example in the synthesis of drug-like compounds. Its listed applications are perborate powder detergents, liquid detergents, concentrated fabric softeners, soaps, alcoholic fine fragrances, toiletries and antiperspirants. It is stored in a cool, dry place in tightly sealed containers, protected from heat and light.

Цікавий факт

Tetralin, the parent hydrocarbon of 6-acetyltetralin, was used in sodium-cooled fast reactors as a secondary coolant to keep sodium seals around pump impellers solidified, until NaK superseded it.

Отримання й хімія

Спосіб отримання

Tetralin, the parent hydrocarbon of 6-acetyltetralin, is made by the catalytic hydrogenation of naphthalene, traditionally over nickel catalysts, and too much hydrogenation turns it into decalin. Tetralin derivatives can be prepared by the Darzens tetralin synthesis, an intramolecular electrophilic aromatic substitution of a 1-aryl-pent-4-ene with concentrated sulfuric acid.
