摘要： A method of purifying ammonia borane is provided whereby crude ammonia borane is dissolved in a basic aqueous solution, the solution is heated to decompose and precipitate impurities found in the crude ammonia borane, and the impurities are separated by filtration. The aqueous solution containing dissolved ammonia borane is then cooled to a temperature of from 10° C. to −10° C., to precipitate the ammonia borane, which is recovered and dried to yield a high-purity product.

摘要翻译： 提供了一种纯化氨硼烷的方法，其中将粗氨硼烷溶解在碱性水溶液中，将溶液加热分解并沉淀在粗氨甲烷中发现的杂质，并通过过滤分离杂质。 然后将含有溶解氨硼烷的水溶液冷却至10℃至-10℃的温度，以沉淀氨硼烷，将其回收并干燥，得到高纯度产物。
