【摘要】 本工艺将醋酸溶液投入反应釜中,加入烧碱中和,充分搅拌得醋酸钠水溶液。加热浓缩后冷却结晶,离心脱水得粗品,经重结晶,干燥后得无水醋酸钠,并通过红外、脱水率及SEM对产品进行了实验验证。通过工艺设计,确定了各段的工艺参数,并对总工艺流程和重结晶工艺流程进行了设计。更多还原

【Abstract】 This technology prepared sodium acetate solution with agitating acetic acid and caustic soda mixture solution in a reactor.The rough product obtained by concentration,cooling and centrifugation of the mixture reaction solution.The anhydrous sodium acetate crystal was got by recrystallization and dehydrating.The final product was studied by infrared spectroscopy analysis,scanning electron microscope analysis,and dewatering rate.The whole technology and the recrystallization processes were designed and the optimum technology parameters were determined.更多还原
