岩征水热合成反应釜是实验室消解常用的仪器,使用范围广,价格优惠,深受科研工作者好评!但是这常用不起眼的小仪器如果使用不当,也会带来安全上的隐患!岩征仪器提醒使用水热反应釜,水热合成反应釜请注意以下事项:

1.将反应物倒入聚四氟乙烯衬套或PPL衬套内,并保证加料系数小于0.8。

2.确保釜体下垫片位置正确(凸起面向下),然后放入聚四氟乙烯衬套或PPL衬套和上垫片,先拧紧釜盖,然后用螺杆把釜盖旋扭拧紧为止。

3.将水热合成反应釜置于加热器内,按照规定的升温速率升温至所需反应温度。(小于规定的安全使用温度)。

4.当确认釜内温度低于反应物系种溶剂沸点后方能打开釜盖进行后续操作。待反应结束将其降温时,也要严格按照规定的降温速率操作,以利安全和反应釜的使用寿命。

5.确认釜内温度低于反应物系种溶剂沸点后,先用螺杆把釜盖旋扭松开,然后将釜盖打开。

6.水热合成反应釜每次使用后要及时将其清洗干净,以免锈蚀。釜体、釜盖线密封处要格外注意清洗干净,并严防将其碰伤损坏。

Hydrothermal synthesis reactor operation methods:

1.Pour the reaction into a polytetrafluoroethylene liner or PPL liner, and to ensure that the feeding coefficient less than 0.8.

2.Make sure that the kettle body gasket in the correct position (convex face down), then put into the PTFE bushing or PPL bush and upper gasket, first tighten kettle lid, then screw the kettle lid knob tighten until.

3.Place the hydrothermal synthesis reaction kettle in a heater, the temperature was raised to the desired reaction temperature in accordance with a predetermined heating rate. (Less than a predetermined safe operating temperature).

4.When confirm kettle temperature is below the boiling point of the reactants lines kinds of solvents in order to open the kettle lid for subsequent operations. After the completion of the reaction to cool, but also strictly accordance with the provisions of the cooling rate operation, to facilitate the safety and reactor service life

5.After confirming that the the autoclave temperature below the boiling point of the solvent of the reaction system species, first use the screw to release the autoclave lid knob , and then open the autoclave lid .

6.Hydrothermal synthesis reactor must be promptly cleaned after each use to prevent corrosion.Pay special attention to clean the kettle body, kettle cover line seal and take strict precautions against its bumps damage.
