ABSTRACT
Recrystallized in
multiple solvent consisting of ethanol,low-carbon alcohol and water,antioxidant1010 was
refined,and the main factors of affecting crystalliza tion including solvent,water et.
al.were studied in the laboratory,and individua l delta-form crystals of antioxidant1010
with good stability,fast drying speed,hi gh purity,heavy bulk density,good flowability,low
volatility was obtained.
Key words:antioxidant1010;recrystallization;delta-form
