| titleOfInvention | Method for separating adamantanols |
| abstract | (57) Abstract: An adamantanetriol is obtained from a mixture of adamantanetriols having three hydroxyl groups and adamantanols having a different number of hydroxyl groups such as adamantanemonols, adamantanediols, and adamantanetetraols. Separation is simple and efficient. SOLUTION: An aqueous solution or an aqueous dispersion of a mixture of adamantanetriols and adamantanols having different numbers of hydroxyl groups is brought into contact with ethyl acetate at a temperature of 40 ° C. or more, so that the ethyl acetate phase has 3 hydroxyl groups. The following adamantanols are distributed to the aqueous phase with adamantanols having 4 or more hydroxyl groups. Then, after separating the ethyl acetate phase, cooling is performed to precipitate crystals of adamantanetriols. Adamantane monools and adamantane diols do not precipitate even when cooled, and the precipitated crystals become adamantane triols with high purity. |
