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 cr ystals
