물성

물과는 임의의 비율로 혼합되지만, 염화칼슘의 찬 포화 용액에는 녹지 않으므로 에틸알코올과 구별된다. 에틸알코올, 에테르에도 임의의 비율로 혼합된다. 산화하면 프로피온알데히드가 되며 다시 프로피온산이 된다. 황산에 의해 탈수하면 프로필렌이 되며 여기에 요오드화수소를 첨가한 후 가수 분해하면 이소프로필알코올을 생성한다 240~250℃로 수산화칼륨을 작용시키면 프로피온산과 프로필렌이 된다. 브롬과는 반응하여 1, 1-디브로모프로피온알데히드와 브롬화프로필을 생성하며 요오드와 수산화칼륨에서는 요오도포름을 생성한다.

합성

염화에틸마그네슘과 트리히드록시메틸렌을 반응시킨다. 또 프로피온알데히드를 환원해도 좋다. 공업적으로는 천연물에서 분별 증류로 얻어지며 메틸알코올 합성의 부산물로서 얻어진다.

개요

1-propanol is the compound with the hydrogen atom in the propane molecules being replaced by hydroxyl group. Because the hydroxyl group can substitute the hydrogen atoms contained in the carbons in the two terminals of carbon chain or middle carbon, thus generating two isomers, n-propyl alcohol and isopropyl alcohol.
The chemical property of the 1-propanol is similar to that of ethanol. It is the byproduct during the process of the methanol synthesis from carbon monoxide and hydrogen. At room temperature and normal pressure, it appears as colorless transparent liquid with fragrance odor. In industry, it is prepared through the reaction between ethylene, carbon monoxide and hydrogen under high pressure and cobalt catalysis; alternatively through the hydration of propylene under the action of sulfate or through the catalytic hydrogenation of acetone. It is commonly used as a solvent with irritating effect on the eyes and mucosa. Inhalation of propyl alcohol steam can lead to dizziness, headache and vomiting, etc.

화학적 성질

1-Propanol is a clear, colorless liquid with an alcoholic odor and a characteristic ripe, fruity flavor. It is soluble in water and miscible with organic solvents (Propanols). It has better dissolution properties than ethanol for fats and oils, and dissolves polar resins in the same way as ethanol. Cellulose nitrate and poly(vinyl acetate) are, however, almost insoluble. For economic reasons propanol is of only limited use as a solvent, and is a starting material for esters.

물리적 성질

Colorless liquid with a mild, alcohol-like odor. Experimentally determined detection and recognition odor threshold concentrations were <75 μg/m³ (<31 ppb_v) and 200 μg/m³ (81 ppb_v), respectively (Hellman and Small, 1974). An odor threshold concentration of 100 ppb_v was reported by Nagata and Takeuchi (1990).

Also reported found in apple, apricot, banana, sweet cherry, papaya, pineapple, orange juice, lingonberry, cranberry, grapes, peas, pineapple, raspberry, strawberry, onion, leek, tomato, ginger, vinegar, many cheeses, butter, fatty fish, fish oil, cooked beef, mutton and pork, beer, several types of bread, pear brandy, Scotch blended whiskey, malt whiskey, cognac, armagnac, weinbrand rum, bourbon whiskey, Irish whiskey, rum, grape wines, cider, sherry, cocoa, tea, roasted filberts and peanuts, honey, soybean, oats, passion fruit, plum, beans, mushroom, apple and plum brandy, gin, rice, rice bran, quince, prickly pear, jackfruit, sake, buckwheat, loquat, wild rice, anise brandy, endive, truffle, arrack, clam, cape gooseberry and Chinese quince.

용도

1-Propanol is used in making n-propyl acetate; and as a solvent for waxes, resins, vegetable oils, and flexographic printing ink. It is produced from the fermentation and spoilage of vegetable matter.

주요 응용

The propanols are used mainly as solvents for coatings; in antifreeze compositions and household and personal products; and as chemical intermediates for the production of esters, amines, and other organic derivatives. As a solvent, 1-propanol is used principally in printing inks, paint, cosmetics, pesticides, cellulose esters and insecticides.
1-Propanol is used commercially to produce glycol ethers. These are characterized by dual functionality, which imparts high solvency, chemical stability, and water compatibility.

제조 방법

1-Propanol is produced commercially by the oxo process by reacting ethylene with carbon monoxide and hydrogen in the presence of a catalyst to give propionaldehyde, which is then hydrogenated. 1-Propanol [71-23-8] is the major product of catalytic reduction of propanal (→Propanols). Reduction is carried out most economically by a continuous vapor-phase process over a heterogeneous catalyst of supported reduced nickel, copper, and/or zinc and manganese metals.

정의

ChEBI: 1-Propanol is the parent member of the class of propan-1-ols that is propane in which a hydrogen of one of the methyl groups is replaced by a hydroxy group. It has a role as a protic solvent and a metabolite. It is a short-chain primary fatty alcohol and a member of propan-1-ols.
