CA 是以精制短棉绒经醋酸活化,在硫酸催化剂存在下,用醋酸和酯酐混合液使之乙酰化,然后加稀醋酸水解到所需的酯化度的产物。按照酯化度不同,可分为一醋酸纤维素、二酯酸纤维素、三醋酸纤维素。酯化度不同而有不同的性质和用途。酯化度大小对溶解性能有很大影响,酯化度降低则在极性溶剂中的溶解度增加,但在非极性溶剂中溶解度减小。醋酸含量60%-61.5%的三醋酸纤维素,因含羟基少,对水不敏感,可溶于二氯甲烷等。醋酸含量51%-58%的二醋酸纤维素为一般工业上用的醋酸纤维素,可溶于丙酮。三醋酸纤维素和 二醋酸纤维素为白色无定形屑状或粉状固体,无明显熔点,220 ℃开始软化。相对密度1.27-1.32,吸水性(24h)1%-4%。 醋酸纤维素可用于配制溶剂型胶粘剂,粘接眼镜、玩具等塑料制品。贮存于阴凉、通风、干燥的库房内。防雨、防晒。
