补充产品信息:
格氏试剂是由法国化学家Victor Grignard发现于1900年的有机金属化合物。这类以“RMgX”为通式的化合物能够由卤代烃与金属镁在乙醚等无水溶剂中1)制备得到，并且已经广泛地用于有机合成中。
格氏试剂通常以溶液的形式使用，一般呈现为浅灰色至浅棕色透明溶液。它们一般以烷基卤化镁(RMgX)和二烷基镁(R2Mg)的中间态存在，是和复杂组分形成的平衡态混合物 (称为“Schlenk平衡”)。2) 此外，其中的一些种类可能由于溶解度降低而产生沉淀。但这并不会影响它们的实际使用。
当出现沉淀时：
请轻轻地摇晃瓶子使悬浮物充分分散后使用（如果沉淀物的量非常少，您可以使用悬浮液的上层清液）。特别是在冬天等寒冷的条件下，可能经常生成大量沉淀物。这种情况下，请用干燥的玻璃棒捣碎后使用。此外，您也可以按如下方法使用：将瓶子放进塑料袋后浸入40℃的水浴中使固体溶解。请注意瓶子开启时有机溶剂的挥发。
