9,9-双(6-羟基萘-2-基)芴的溶剂合物晶体及其制备
摘要：
本发明公开了一种9,9-双(6-羟基萘-2-基)芴的溶剂合物晶体及其制备，由9,9-双(6-羟基萘-2-基)芴与乙腈制备的溶剂合物结晶为9,9-双(6-羟基萘-2-基)芴的溶剂合物晶体I，由9,9-双(6-羟基萘-2-基)芴与乙酸乙酯制备的溶剂合物结晶为9,9-双(6-羟基萘-2-基)芴的溶剂合物晶体II。本发明制备的9,9-双(6-羟基萘-2-基)芴溶剂合物晶体I和晶体II脱溶剂化后的最大熔融吸热峰在261～266℃,堆积密度大于0.4g/mL，热稳定性高,在40℃保存三个月颜色和纯度基本不变，堆密度高、流动性好，易于转移加料。
摘要（英）：

The invention discloses a solvate crystal of 9,9-bis(6-hydroxy naphthalene-2-group) fluorene and preparation thereof. A solvate crystal prepared from the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene and acetonitrile is a solvate crystal I of the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene, and a solvate crystal prepared from the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene and ethyl acetate is a solvate crystal II of the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene. The solvate crystal I and solvate crystal II of the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene, which is prepared through the invention achieve the maximum melting endothermic peaks of 261-266 DEG C and the stacking density of 0.4 g/mL after being desolvated, is basically unchanged in color and purity after being preserved at 40 DEG C for three months due to high heat stability and has the advantages of high stacking density, good flowability and easiness for loaded material transfer.
