确认反应釜反应结束后,缓慢排放氢气至尽(注意内稍有压力就关闭排气阀,以免氧气进入),打开进气阀,冲入氮气至0.2Mpa关闭进气阀,然后缓慢打开排气阀,放出里面的混合气体,将尽时重新输入氮气,如此换气三次后,用真空泵抽出液面上的气体,打开排气阀、取样阀,开始从底阀放料(注意,由于里面有遇氧易自燃的物质如Pa/cRaneyNi,因此杜绝洒落在盛器外),如有洒漏,请立即用湿毛巾将其蘸出,放入有水的桶内,后用少量稀酸将其破坏掉,放料毕立即关闭底阀门。

Confirm the end of thereactor www.gfanyingfu.com after reaction, hydrogen to slow discharge (note that in slightpressure to close the exhaust valve, the inlet valve is opened, oxygen enters),nitrogen gas into the 0.2Mpa to close the inlet valve, and then slowly open theexhaust valve, the mixed gas released inside, will do when the new input ofnitrogen, so ventilation three after using the vacuum pump out of gas on thesurface, open the exhaust valve, sampling valve, discharge valve from the start(note that because there are oxygen in the spontaneous combustion of substancessuch as Pa/c, RaneyNi and so on in the container, put an end to outside) ifthere is leakage, please be with a wet towel immediately into there is water inthe barrel, with a small amount of dilute acid will destroy the discharge valveimmediately shut down the bottom end.

 

放完料的反应釜,应立即清洗,清洗前应按以下步骤进行:

After discharge the reactionvessel, should be cleaned immediately before cleaning should be carried outaccording to the following steps:

 

1、将反应溶剂从排气阀充入釜内,清洗掉大部份残留物后,注入水半釜进行搅拌10分钟,此时方可打开釜盖,对釜内壁进行清洗;

1,the reaction solvent from the exhaust valve charging into the tank, cleaningout most of the residues, the injection of water into the pot for 10 minutes,then open the lid, the inner wall of the tank cleaning;

 

2、清洗时,必须清洗釜盖、取样阀,同时在釜内有水的情况下,稍充一下氮气;

2,cleaning, must clean the kettle cover, sampling valve, while there is water inthe kettle, a little filling nitrogen;

 

3、暂时不用的反应釜,最好将反应釜内加入70%体积干净的无水乙醇浸泡,可以不拧紧螺丝。

3,temporarily without the reactor, it is best to add 70% volume of the reactorinto a clean ethanol soak, you can not tighten the screws.
