一般說明

碳酸氢钠,也被称为小苏打,通常被用作温和的碱来中和酸性溢出,调节pH值,并抵消体内某些酸性毒素的影响。当与醋或柠檬汁等酸性成分反应时,它还会产生CO ,从而起到发酵剂的作用。

應用

碳酸氢钠用作

  • :在合成1,2:5,6-二- o -环己基- d -甘露醇和2,3-环己基- d -甘油醛的过程中,作为温和碱来中和反应混合物。
  • 沉淀剂,在共沉淀法中合成γ -氧化铝(γ-Al2O3)催化剂过程中甲醇脱水反应生成二甲醚。
  • 为设计高性能薄膜复合正向渗透(TFC-FO)膜,研究了多孔聚醚砜支撑层形成过程中提高基质孔隙度的成孔剂和CO2源。

  • Contactless conductivity sensor employing moist paper as absorbent for in-situ detection of generated carbon dioxide gas.: This study utilizes sodium bicarbonate in a novel approach for the development of a contactless conductivity sensor. The sensor uses moist paper to absorb CO2 gas generated from sodium bicarbonate, demonstrating its potential for environmental monitoring and analytical applications (Sonsa-Ard et al., 2020).
