δ-型抗氧剂1010及其结晶制备 孙延喜 常桂祖 魏玉德 摘要:在乙醇、低级醇A和水三元混合溶剂中, 通过对抗氧剂1010粗品的重结晶精制研究,
制备得到了纯度高、堆密度大、流动性好、挥发份低、质量稳定、干燥速度快的δ-型抗氧
剂1010。 Individual delta-form
crystals of antioxidant 1010 SUN Yan-xi,CHANG
Gui-zu,WEI Yu-de 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. 作者简介:孙延喜(1969-),男(汉族),甘肃省兰州市人,工程师,硕士。已申请专利三项。
