Abstract

Η παρούσα ευρεσιτεχνία αφορά μέθοδο παρασκευής ξηρού θειοκτικού οξέος, κατά την οποίαν υπάρχον ακατέργαστο υλικό, εμπλουτισμένο σε θειοκτικό οξύ, υποβάλλεται σε επεξεργασία με υγρό, ή υπέρ το κρίσιμο σημείον CO2, και έτσι, με μία απλή τεχνική μέθοδο, φθάνουμε σε θειοκτικό οξύ με χαμηλές περιεκτικότητες υπολοίπων διαλυτών.
