1-propanol. C 3 H 8 O(60.10). CH 3 CH 2 CH 2 OH. Sometimes used to refer to aliphatic saturated alcohols with three carbon atoms, but 1-propanol, which has a hydroxyl group at the terminal carbon, is the term used. Also called n -propanol. A few percent of fusel oil contains it. In the laboratory, it is obtained by reacting ethylmagnesium chloride with trioxymethylene. In industry, it is either distilled from fusel oil or synthesized by hydrogenating propionaldehyde, which is obtained by oxo synthesis from ethene, carbon monoxide, and hydrogen. It is also obtained as a by-product in the synthesis of methanol. A colorless liquid with an odor similar to ethanol. Melting point -126.2 °C, boiling point 97.21 °C. 0.79948. 1.38355. Explosive range 2.1-13.5% by volume. Easily soluble in water, ethanol, and ether. Used as a solvent for paints, printing inks, etc. [CAS 71-23-8][See other terms] Isopropyl alcohol Source: Morikita Publishing "Chemical Dictionary (2nd Edition)" Information about the Chemical Dictionary 2nd Edition |
1-propanol.C3H8O(60.10).CH3CH2CH2OH.炭素数3の脂肪族飽和アルコールを総称する場合もあるが,そのうちとくに末端炭素にヒドロキシ基をもつ1-プロパノールをいう.n-プロパノールともよばれる.フーゼル油中に数% 含まれる.実験室的には,塩化エチルマグネシウムとトリオキシメチレンとの反応で得られる.工業的には,フーゼル油から分留するか,エテン,一酸化炭素および水素からオキソ合成で得られるプロピオンアルデヒドを水素化して合成される.また,メタノール合成の副生物としても得られる.エタノールに似た香りをもつ無色の液体.融点-126.2 ℃,沸点97.21 ℃.0.79948.1.38355.爆発範囲2.1~13.5体積%.水,エタノール,エーテルに易溶.塗料,印刷インキなどの溶剤として用いられる.[CAS 71-23-8][別用語参照]イソプロピルアルコール 出典 森北出版「化学辞典(第2版)」化学辞典 第2版について 情報 |
