Propan-1-ol

1-프로판올 C화학적 특성, 용도, 생산

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.

Purification Methods

The main impurities in n-propyl alcohol are usually water and 2-propen-1-ol, reflecting the commercial production by hydration of propene. Water can be removed by azeotropic distillation either directly (azeotrope contains 28% water) or by using a ternary system, e.g. by also adding *benzene. Alternatively, for removal of gross amounts of water, reflux over CaO for several hours is desirable, followed by distillation and a further drying. To obtain more nearly anhydrous alcohol, suitable drying agents are firstly NaOH, CaSO4 or K2CO3, then CaH2, aluminium amalgam, magnesium activated with iodine, or a small amount of sodium. Alternatively, the alcohol can be refluxed with n-propylsuccinate or phthalate in a method similar to the one described under EtOH. Allyl alcohol is removed by adding bromine (15mL/L) and then fractionally distilling from a small amount of K2CO3. Propionaldehyde, also formed in the bromination, is removed as the 2,4-dinitrophenylhydrazone. n-Propyl alcohol can be dried down to 20ppm of water by passage through a column of pre-dried molecular sieves (type 3 or 4A, heated for 3hours at 300o) in a current of nitrogen. Distillation from sulfanilic or tartaric acids removes impurities. Albrecht [J Am Chem Soc 82 3813 1960] obtained spectroscopically pure material by heating with charcoal to 50-60o, filtering and adding 2,4-dinitrophenylhydrazine and a few drops of conc H2SO4. After standing for several hours, the mixture is cooled to 0o, filtered and distilled in a vacuum. Gold and Satchell [J Chem Soc 1938 1963] heated n-propyl alcohol with 3-nitrophthalic anhydride at 76-110o for 15hours, then recrystallised the resulting ester from H2O, *benzene/pet ether (b 100-120o)(3:1), and *benzene. The ester was hydrolysed under reflux with aqueous 7.5M NaOH for 45minutes under nitrogen, followed by distillation (also under nitrogen). The fraction with b 87-92o is dried with K2CO3 and stirred under reduced pressure in the dark over 2,4-dinitrophenylhydrazine, then freshly distilled. Also purify it by adding 2g NaBH4 to 1.5L of alcohol, gently flushing with argon and refluxing for 1day at 50o. Then 2g of freshly cut sodium (washed with propanol) is added and refluxed for one day, and finally distilled, taking the middle fraction [Jou & Freeman J Phys Chem 81 909 1977]. [Beilstein 1 IV 1413.]

비 호환성

Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, perox- ides, permanganates, perchlorates, chlorine, bromine, fluo- rine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. n-Propanol reacts with alkali metal, nitrides and strong reducing agents to give flammable and/ or toxic gases. Reacts with oxoacids and carboxylic acids to form esters plus water. Converted by oxidizing agents to propanal or propionic acid. May initiate the polymerization of isocyanates and epoxides

폐기물 처리

Dissolve or mix the material with a combustible solvent and burn in a chemical incinera- tor equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
