Abstract
A process for preparing aluminophosphate compounds (and substituted derivatives) of the structural type VFI. This preparation process is characterized in that the speed of increase in temperature of the reaction mixture is greater than 250.degree. C./hour, the total time of heating of the reaction mixture, including the rise in temperature and the plateau heating, being less than one hour. The temperature of the plateau heating is between 100.degree. and 200.degree. C. The synthetic compounds in accordance with the invention possess
