一般說明

碱石灰是氢氧化钙与氢氧化钠或氢氧化钾的混合物。如果没有储存在密封的容器中,它会因为吸收二氧化碳和水分而迅速变质。在实验室中,它也用作干燥剂。
苏打石灰对七氟烷降解的影响已被研究。降解产物的毒性已被研究。

應用

碱石灰可:
  • 用作一种水解试剂,以靛红酸酐中合成灭草松。
  • 用于农田土壤CO2的排放监测。
  • 用于直接测定溶解于过饱和水中的CO2(二氧化碳)含量。

苏打石灰可用于将α-氨基酸转化为伯胺。

The Science of the total environment, 408(4), 976-984 (2009-11-11)
Several exposure campaigns of silica-soda-lime window glass have been performed in 30 European sites and 1 in Canada in order to understand, quantify and model the phenomenon of soiling. In this purpose samples were exposed sheltered from the rain. Parallel

Anesthesia and analgesia, 110(3), 747-753 (2010-02-27)
Carbon monoxide (CO) can be produced in the anesthesia circuit when inhaled anesthetics are degraded by dried carbon dioxide absorbent and exhaled CO can potentially be rebreathed during low-flow anesthesia. Exposure to low concentrations of CO (12.5 ppm) can cause

Optics express, 20(5), 5429-5439 (2012-03-16)
Materials presenting high optical nonlinearity, such as materials containing metal nanoparticles (NPs), can be used in various applications in photonics. This motivated the research presented in this paper, where morphological, linear and nonlinear optical characteristics of gold NPs on the
