合成方法

1.将精制短棉绒干燥后，经醋酸活化，再在醋酸催化剂存在下，与醋酸和醋酐混合液进行酯化反应，使之乙酸化，然后加稀醋酸水解。中和催化剂，使产物深沉析出，经脱酸洗淀、精煮、干燥可得。

2.将精制短棉绒干燥后，经醋酸活化，再在硫酸催化剂存在下，与7倍于精制短棉绒的醋酸和醋酐混合液进行酯化反应，使之乙酸化，然后加稀醋酸水解到所需要的水解度（1.72～1.95）。中和催化剂，使产物沉淀析出，经脱酸洗涤、精煮、干燥后即得一醋酸纤维素。在乙酰化反应时，改变加入的醋酸和醋酐混合液的量，可制得二醋酸纤维素和三醋酸纤维素。醋酸和醋酐混合液的量为精制短棉绒的8.5倍，反应毕加稀醋酸水解达到取代度为2.28～2.49，得到二醋酸纤维素。醋酸和醋酐混合液的量为精制短棉绒的10倍，反应毕加稀醋酸水解达到取代度为2.8～2.9，得到三醋酸纤维素。

用途

1.用于制药品的肠溶衣、醋酸纤维过滤膜等, 用于制醋酸纤维塑料、醋酸纤维素过滤膜等

2.可用于配制溶剂型胶黏剂，粘接眼镜、玩具等塑料制品。是纤维素酯中应用最广的一种，根据不同的乙酸纤维素品种及选择相应的助剂，可制成机械、汽车、飞机、电气设备的相关部件及家庭日用品等。二乙酸纤维素可用丙酮溶解后，经纺丝而用作香烟过滤嘴及纺织材料；加入增塑剂可制成塑料膜，可用注塑成型工艺制成板、管、棒、包装容器及车把、手柄、笔杆等用品；还可用于制造录音胶带、反渗析膜、包装薄膜、电容器薄膜、玻璃纤维粘接剂及涂料等。三乙酸纤维素可用氯甲烷溶解后纺丝制作乙酸纤维及相应纺织材料，也可用流延成膜工艺制造照相和电影胶片、Ｘ射线底片、绝缘薄膜隔膜、高压电机的扁电线绝缘等。医用乙酸纤维素还广泛用来制造血液透析和血液过滤膜、人工肾膜材料等。

型号	用途	特性
Eastman™ Cellulose Acetate (CA-398-10)	涂料、涂料玻璃、涂料纸/纸板、消费类电子产品、电动、压敏胶粘带、木材密封剂	Eastman™ CA-398-10 is a low viscosity solution grade of cellulose acetate.
Eastman™ Cellulose Acetate (CA-398-3)	涂料、涂料玻璃、涂料纸/纸板、消费类电子产品、电动、食品包装、食品接触应用、压敏胶粘带、木材密封剂	Eastman Cellulose Acetate (CA-398-3) is one of the lower viscosity solution grades of cellulose acetate. The average ASTM viscosity of CA-398-3 is 3 seconds. Eastman Cellulose Acetate (CA-398-3) is supplied in the form of a fine, dry, free-flowing powder. This multipurpose rheology enhancer, provides high strength and good resistance to ultraviolet light, heat, oils and greases. Useful in lacquers for glass, plastic, wire and release coatings. It may be blended with appropriate solvents, plasticizers, and other modifying resins to formulate coatings for paper, glass, plastic, wire screen, and electrical wiring. Food additive regulations issued by the Food and Drug Administration (FDA) permit use of cellulose acetate in specific food packaging applications. Cellulose acetate is also prior sanctioned for use in film in food-contact applications. CA is also recognized by the FDA as generally recognized as safe (GRAS) for use in paper and paperboard in contact with food.
Eastman™ Cellulose Acetate (CA-398-30)	压敏胶粘带、密封胶	Eastman™ Cellulose Acetate CA-398-30 is a high-viscosity, high molecular weight cellulose acetate supplied as fine, dry, free-flowing powder. The powder is free from coarse particles and excessive fines. Its relatively uniform particle size permits good plasticizer distribution during blending. Cellulose acetate CA-398-30 offers good physical properties for molded and extruded articles. It may be compounded into plastic using extrusion equipment or heated rolls.
Eastman™ Cellulose Acetate (CA-398-6)	压敏胶粘带、密封胶	Eastman™ Cellulose Acetate (CA-398-6) is a low viscosity solution grade cellulose acetate. Eastman™ cellulose acetate is supplied in the form of fine, dry, free-flowing powder. Food additive regulations issued by the Food and Drug Administration (FDA) permit use of cellulose acetate in specific food packaging applications. Cellulose acetate is also prior sanctioned for use in film in food-contact applications. CA is also recognized by the FDA as generally recognized as safe (GRAS) for use in paper and paperboard in contact with food.
