摘要
PCT No. PCT/EP92/02159 Sec. 371 Date Dec. 3, 1993 Sec. 102(e) Date Dec. 3, 1993 PCT Filed Sep. 18, 1992 PCT Pub. No. WO93/06043 PCT Pub. Date Apr. 1, 1993The invention relates to a method for the continuous preparation of vanadium pentoxide gel and an apparatus for implementing the method. According to the present invention, the vanadium pentoxide is raised to a temperature at least 100 DEG C. higher than its melting point; it is poured continuously into a quenching reactor 2 containing distilled water at ambient temperature; the gel obtained flows by overflowing to an ageing reactor 4, the contents of which are recirculated to the quenching reactor; the concentration of the gel contained in the ageing reactor 4 is measured continuously so as to adjust continuously the quantity of distilled water to be added to the quenching reactor 2; the contents of the ageing reactor are evacuated into a storage drum 9. Application to the manufacture of vanadium pentoxide for anti-static applications.
