Application

磷酸可用作测定普通磷脂的磷-31核磁共振（31磷核磁共振）化学位移的标准。它可用于以下研究：
  • 作为31P核磁共振波谱分析人脑白质脂质组成的外部标准。
  • 31P NMR波谱作为组蛋白H4酸不稳定磷酸化的外部标准。
  • 作为参考标准，通过反应前和反应后质谱31核磁共振和傅里叶变换红外光谱法研究二氧化硅/氧化铝负载的磷酸钠上存在的表面物质。
  • 作为催化剂在一系列表面改性和未改性的ZSM-5上（623K）苯乙酸酯的气相弗里斯重排。

General description

磷酸 (H 3 PO 4 ) 在工业上用于处理金属表面以获得更好的涂料和树脂涂层的附着力。
We are committed to bringing you Greener Alternative Products that adhere to one of the four categories of Greener Alternatives. Phosphoric acid is an enabling product which enhances the sustainability of lithium-ion batteries by improving the ionic conductivity of solid-state electrolytes through water-mediated synthesis. This process reduces reliance on harmful solvents, minimizes waste, and promotes the formation of structures that facilitate lithium ion transport, demonstrating a commitment to greener chemistry and efficient energy storage solutions.
