Product introduction
无气味。对光敏感。微吸湿。200℃以下稳定。易溶于水、无水乙醇、甲醇和丙酮,微溶于乙醚和氯仿,几乎不溶于石油醚。在水溶液中逐渐分解而浑浊,矿酸能促进分解,加入数滴稀氢氧化钠溶液可延缓分解。水溶液的pH调节到约5时,可以在室温中保存,如在45℃,该溶液可保存5天而不变质。有刺激性。钾的重量法和滴定法测定。生物碱、季铵盐等大阳离子的缔合沉淀。测血钾用。测定钾、铷、铯、汞、铊及有机碱(生成碱);通过离子交换得到稳定的、结晶性N-酰胺盐。与三氟甲磺酸乙烯基酯或芳基酯偶联形成芳烯烃和联芳基化合物。 应用: · 四苯硼钠可与胺、铵离子和大碱金属离子(如铯或铷离子)形成疏水盐。因此,它通常在重量分析中用作沉淀剂。 · 通过离子交换得到稳定的、结晶性N-酰胺盐。[3]与三氟甲磺酸乙烯基酯或芳基酯偶联形成芳烯烃和联芳基化合物。 Application: · Generates stable, crystalline N-acylammonium salts by ion exchange.[2] Couples with vinyl and aryl triflates to form arylalkenes and biaryls. · Sodium tetraphenylborate can form hydrophobic salts with amines, ammonium ions, and large alkali metal ions such as cesium or rubidium ions. Hence it is commonly used in gravimetric analysis as a precipitating agent.
