碳酸氨鈉溶液在加热时則分解,逸出二氧化碳生成碳酸鈉,硷度增大不适用。其反应如下: 2 NaHCO_3(?)Na_2CO_3+H_2O+CO_2 在加热灭菌时,容器在严密封閉下,二氧化碳虽然不致逸去,但亦不能全部进入溶液中、而存于容器的空间,溶液的硷度增大仍不适用。据文献記載,安瓿在熔封之前。均事先通入二氧化碳1—2分鐘,以增加二氧化硬濃度,使反应向左进行。即可制成。但溶液体积与气体流量及通入二氧化碳的时間,均有密切的关系,在操作时尚难掌握,我們对这点进行了改进,具体操作如下:
Sodium carbonic acid solution is decomposed when heated, escape carbon dioxide to produce sodium carbonate, increased alkalinity does not apply. The reaction is as follows: 2 NaHCO_3 (?) Na_2CO_3 + H_2O + CO_2 in the heat sterilization, the container is tightly closed, although carbon dioxide does not escape to, but can not all enter the solution, and stored in the container space, the solution of alkali The degree of increase still does not apply. According to the literature, ampoules before sealing. Prior to the introduction of carbon dioxide for 1-2 minutes, in order to increase the hardness of the dioxin, the reaction to the left. Can be made. However, the solution volume and gas flow and time into the carbon dioxide, are closely related to the operation is difficult to grasp, we have made improvements on this point, the specific operation is as follows:
