Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As depicted in figs. 1 and 2, the horizontal continuous producing apparatus of phosphorus pentafluoride of the invention, including horizontal reacting container 1,
With the liquid level maintaining segment 2 of certain altitude, the 2 arbitrary height position of liquid level maintaining segment in the inner cavity of the horizontal reacting container 1
The area equation for the horizontal cross-section set, the lower section of the liquid level maintaining segment 2 are provided with feed pathway 3, and the horizontal reacting of top holds
1 one end of device is provided with inlet channel 4, and the other end is provided with exhaust passage 5.
Horizontal reacting container 1 uses high-temperature and high-presure resistent reactor, and feed pathway 3 is sleeping for liquid phosphor to be continuously passed through
Formula reaction vessel 1, fluorine gas for being continuously passed through horizontal reacting container 1 by inlet channel 4, and exhaust passage 5 will be for that will react generation
Phosphorus pentafluoride discharge.When due to the yellow phosphorus using solid powder as raw material, it is not easy to control contact of the yellow phosphorus with fluorine gas
Area causes reaction to be not sufficiently stable, and control is not easy.And solid yellow phosphorus is heated as liquid first with heating equipment by the present invention
Then liquid phosphor is passed through horizontal reacting container, then fluorine gas is passed through horizontal reacting container above yellow phosphorus liquid level by state, make
Fluorine gas is merely able to contact with yellow phosphorus liquid level, and it is excessive with the contact area of yellow phosphorus and lead to react excessively violent to avoid fluorine gas.
With the progress of reaction, the yellow phosphorus in horizontal reacting container 1 is constantly consumed, and yellow phosphorus liquid level can reduce, liquid level
It can change, in order to guarantee reacting balance, the liquid level area of liquid phosphor should be as constant as possible, to guarantee fluorine gas and Huang
The contact area of phosphorus remains unchanged, therefore with the liquid level maintaining segment 2 of certain altitude, liquid in the inner cavity of horizontal reacting container 1
The area equation of the horizontal cross-section of 2 arbitrary height position of face maintaining segment.Liquid level maintaining segment 2 is the position required where yellow phosphorus liquid level
Range, it is the liquid levels maintaining segment 2 such as 10mm, 20mm, 30mm that the liquid level maintaining segment 2 of certain altitude, which specifically can be height,.It is reacting
In the process, it is continuously added to new liquid phosphor according to the depletion rate of yellow phosphorus, yellow phosphorus liquid level is made to be in liquid level maintaining segment 2 always
In, it can guarantee that the contact area of fluorine gas and yellow phosphorus remains unchanged, reaction rate is avoided biggish fluctuation occur.
It is excessively violent to avoid reacting in order to react fluorine gas only with the liquid level of yellow phosphorus, and convenient for control reaction rate, fluorine
Gas is merely able to be passed through from the top of liquid level maintaining segment 2, i.e., the horizontal reacting that 2 top of liquid level maintaining segment is arranged in feed pathway 3 holds
In device 1.
In order to guarantee that reacting balance, the liquid level of liquid phosphor should also be steady, can not occur biggish fluctuation, liquid as far as possible
State yellow phosphorus generally uses delivery pump as power-equipment, with certain stream when new liquid phosphor enters horizontal reacting container 1
Speed will necessarily cause to impact, and then lead to yellow phosphorus liquid fluctuating to existing liquid phosphor in horizontal reacting container 1, in order to subtract
Feed pathway 3, is arranged in the lower section of liquid level maintaining segment 2 by small this percussion, it is desirable to is arranged in horizontal reacting container 1
Bottom, the liquid phosphor being newly added in this way from bottom enter and mix with original yellow phosphorus, can slow down to horizontal reacting appearance
The impact of existing liquid phosphor in device 1, keeps yellow phosphorus liquid level steady.
Although existing conventional gas-liquid reactor also has feed inlet, discharge port etc., above-mentioned requirements are obviously unable to satisfy,
Be not suitable for the present invention claims phosphorus pentafluoride preparation process, the present invention is the setting of making of preparation process for phosphorus pentafluoride
Meter has the advantages that simple structure, reacting balance, reaction controllability are good.
