The patient experienced severe reaction with potassium and sodium. By high heat decomposition of toxic gases. It is corrosive to most metals in case of tide. In case of high fever, the internal pressure of the container increases, and there is a risk of cracking and explosion.
with vanadium pentoxide and activated carbon as raw materials, chlorine gas was introduced for chlorination reaction.
used as a catalyst for Copolymerization of ethylene-propylene rubber and ethylene-cyclopentadiene. It is also a variety of organic compounds solvent, can also be used for the synthesis of organic compounds of vanadium.
rat oral LDso:140mg/kg. It is irritating and corrosive to eyes, skin and mucous membranes. Inhalation can cause lung damage. Oral cause oral, throat, chest and stomach severe burning pain. Staff should be protected. If the skin and eyes are touched, they should be immediately rinsed with plenty of flowing water. Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat source.

purpose | is the preparation of ethylene-propylene rubber, ethylene-cyclopentadiene copolymerization catalyst |
production method | vanadium pentoxide and activated carbon are used as raw materials, and chlorine gas is introduced for chlorination reaction. It can be prepared by reacting a mixture of vanadium pentoxide and carbon with chlorine. The reaction tube used is a product with an inner diameter of 25mm and a length of 700mm. Since VOCl3 is liquid at room temperature, the outlet of the reaction tube should be bent downward, A water-cooled condenser was connected and a branched flask with a grinding mouth was installed as a receiver for vocl3. 8g of vanadium pentoxide and 6 times the molar ratio of carbon are mixed, the mixture is put into a boat, and then inserted into the center of the reaction tube, and the air in the reaction tube is replaced by a rare gas, this is followed by replacement with dry chlorine gas. Then, the chlorine gas was introduced at a rate of 300/min, and the material portion was heated to 400-° C., and the VOCl3 was accumulated in the receiver. At this time, the receiver was cooled with ice-cooling sodium chloride refrigerant. The discharged gas is introduced into the chlorine gas absorption bottle and completely absorbed. The resulting VOCl3 was processed in a noble gas and stored in ampoules. Further, VOCl3 can also be obtained by reacting vanadium pentoxide with chlorine at 800 to 1000 °c. |
