METHODS OF PURIFYING 1,2,4-BUTANETRIOL AND COMPOSITIONS INCLUDING 1,2,4-BUTANETRIOL |
摘要 |
Methods of purifying BT are disclosed. The method comprises adding at least one polyhydroxyl compound to a crude BT mixture comprising BT and at least one boron-containing compound to form a polyhydroxyl compound/BT mixture. In one embodiment, the polyhydroxyl compound/BT mixture is then heated to a temperature greater than the boiling point of BT but less than the boiling point of the at least one polyhydroxyl compound. In another embodiment, the polyhydroxyl compound/BT mixture is heated to a temperature greater than the melting point of the polyhydroxyl compound, and then to a temperature greater than the boiling point of BT but less than the boiling point of the at least one polyhydroxyl compound. A composition comprising BT is also disclosed.
