摘要： High-yield catalytic production of acrylonitrile at an elevated temperature, from a reaction mixture containing propylene, ammonia and molecular oxygen, utilizing a catalyst comprising an oxide composition having the empirical formula Mo.sub.a Co.sub.b Fe.sub.c X.sub.d O.sub.e wherein X denotes at least one atom of an element selected from among calcium, tungsten, chromium, zirconium, titanium, zinc, manganese, and tin and the atomic ratio a:b:c:d:e is in the range of 12:4 to 10:1 to 6:0 to 1.0:40 to 70, said catalyst being prepared by providing an aqueous mixture containing compounds of the elements, drying the aqueous mixture, and calcining the dried solid product at a temperature of at least 500.degree. C.

摘要： With respect to any overflow from storage tank, without making cutting off or perforation of the tank wall, perpetual maintenance-free outflow is effected by means of a siphon without the use of power pump before overflowing. Auxiliary pools fixed to both ends of siphon are additionally installed. Referring to FIG. 1A, W-curved tube (1) that upon expansion on a plane, assumes a W-shape is used as a siphon. Start-up portions on both sides thereof are used as auxiliary pools. Even when the water level in storage tank (5) lowers to the bottom, a balance is kept by the heads (2) of water held in the auxiliary pools to thereby stop any water flow break in the siphon, enabling perpetual prevention of breakdown of siphon action. Every time the water level in the storage tank once more goes up above the auxiliary pools and set water level (4), by the state of water head (7) similar to that of the siphon tube of FIG. 6 made from the valve 34 of FIG. 7, 38 of FIG, 8, and drainpipe 39, increased water is caused to naturally and rapidly flow out through the siphon.
摘要翻译：对于从储罐溢出的任何溢流而言，在不切断或穿孔罐壁的情况下，在溢流之前通过虹吸管实现永久免维护外流而不使用动力泵。额外安装固定在虹吸两端的辅助水池。参考图1。在图1A中，W形弯管（1）在平面上膨胀时假定W形被用作虹吸管。其两侧的启动部分被用作辅助池。即使储水箱（5）的水位下降到底部，通过辅助水池中的水头（2）保持平衡，从而停止虹吸管中的任何水流断裂，使得永久防止虹吸作用。每当储水箱中的水位再次上升到辅助水池上方并设定水位（4）时，水头（7）的状态与图3的虹吸管的状态类似。由图3的阀34制成。图8的图7,38和排水管39中，增加的水自然并迅速地通过虹吸管流出。
