Abstract

Inventia se refera la un procedeu pentru anhidrizarea acidului boric în strat fluidizat, anhidrizarea fiind efectuata în doua trepte, mentinînd acidul boric în prima trapta la 140 degree C, timp de 15 min, dupa care, în a doua trapta, urmeaza o încalzire a aerului cu 1 degree /min pîna la 260 degree C, temperatura la care materialul se mai mentine timp de 30 min.The invention relates to a process for the anhydration of boric acid in a fluidized bed, the anhydride being carried out in two steps, maintaining the boric acid in the first trap at 140 ° C for 15 minutes, after which, in the second trap, there is a heating of the air with 1 degree / minute to 260 degrees C, the temperature at which the material is maintained for 30 minutes.
