実験手順

Both 1,4-butanediol and tetrahydrofuran are useful as a solvent and raw materials for organic synthesis such as polymeric material. They have been produced through various ways. For example, tetrahydrofuran is produced by (a) catalytic hydrogenation of furan which has been obtained by elimination of carbonyl group from furfural, (b) dehydration cyclization of butanediol obtained by hydrogenation of butynediol which is a reaction product of acetylene and formaldehyde and (c) reaction of 1,4-diacetoxybutanediol and water in the presence of an acid catalyst; and 1,4-butanediol is produced by (d) hydrogenation of butynediol and (e) hydrolysis of 1,4-diacetoxybutane.
