FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Aluminium chloride solution is mixed with sodium orthophosphate solution to obtain an aluminium phosphate suspension and a supernatant fluid. The suspension is precipitated at temperature of 50-70°C. The supernatant fluid is removed and the aluminium phosphate precipitate is sterilised. The mixing, precipitation, removal and sterilisation steps are carried out in a closed system.
EFFECT: method enables to obtain an aluminium-containing adjuvant AlPO4 with high output and sterility.
