| titleOfInvention | Method for producing 1,4-butanediol |
| abstract | PROBLEM TO BE SOLVED: To provide a method for easily purifying crude 1,4-butanediol containing impurities and efficiently producing high-purity 1,4-butanediol. SOLUTION: By flowing a crude 1,4-butanediol melt on a wall cooled to a temperature below the freezing point of 1,4-butanediol in each of the following steps, A crystallization step of obtaining butanediol crystals, and heating the 1,4-butanediol crystals obtained in the crystallization step to a crystal melt by heating the wall surface to a temperature equal to or higher than the freezing point of the 1,4-butanediol crystals. , 4-butanediol is purified by a melt crystallization method comprising a recovery step. |
