解説アランダム,あらんだむ,アメリカのノートン社製の人造コランダム研磨材の商品名。日本ではこの名が古くから使用されていたため、アルミナ質粒子をさす一般名のように使われている。礬土頁岩(ばんどけつがん),ボーキサイト,あるいはバイヤー法のアルミナをアーク炉で溶融すると得られる人造コランダムα-Al2O3の商品名.研磨剤,耐火物などに用いられる.ボーキサイトをコークスと電気炉内で溶融してつくる溶融アルミナや、アルミナ粉末を粘結剤で成形したのち焼成した焼結アルミナなどがある。硬度は焼結アルミナのほうが溶融アルミナよりやや低い。砥石(といし)、研磨布材として多量に使用される。また、るつぼなど耐火物原料としても使用される。
用途有機合成原料。
使用1'-Acetonaphthone is used in the preparation of S(-)-1-(1'-naphthyl) ethanol, an important synthetic intermediate of mevinic acid analog.
一般的な説明Stereoselective reduction of 1-acetonapthone in aqueous media by whole cells of Geotrichum candidum has been investigated in various organic co-solvents. Magnetic field effects on the photoinduced electron-transfer reaction between 1-acetonaphthone and diphenylamine in micellar solution have been studied by laser flash photolysis.
純化方法If the NMR spectrum indicates the presence of impurities, probably 2-acetylnaphthalene, convert the substance to its picrate by dissolving in *benzene or EtOH and adding excess of saturated picric acid in these solvents until separation of picrates is complete. Recrystallise the picrate till the melting point is 118o. Decompose the picrate with dilute NaOH and extract with Et2O. Dry the extract (Na2SO4), filter, evaporate and distil the residue. The 2,4-dinitrophenylhydrazone crystallises from EtOH and has m 259o. [Stobbe & Lenzer Justus Liebigs Ann Chem 380 95 1911, Williams & Osborne J Am Chem Soc 61 3438 1939, Beilstein 7 IV 1292.]
