General description
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CO₂ ，从而起到发酵剂的作用。
Application
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。
- 采用湿纸作为吸收剂的非接触式电导率传感器现场检测产生的二氧化碳气体。：研究利用碳酸氢钠开发新型非接触式电导率传感器。该传感器使用湿纸吸收碳酸氢钠产生的CO2气体，展示了其在环境监测和分析应用方面的潜力（Sonsa-Ard et al., 2020）。

Blood flow through intrapulmonary arteriovenous anastomoses (IPAVA) is increased by acute hypoxia during rest by unknown mechanisms. Oral administration of acetazolamide blunts the pulmonary vascular pressure response to acute hypoxia, thus permitting the observation of IPAVA blood flow with minimal
