Investigation on the preparation of calcium magnesium acetate as deicing salt using furfural wastewater

Calcium magnesium acetate (CMA), an environmentally friendly deicing salt, was prepared from furfural wastewater. A production line of CMA (5t/day) was established according to laboratory study, and CMA was produced using the line. The results indicated that the designed preparation process can be applied to actual production, and acetic acid and water from furfural wastewater basically attain to zero discharge due to be recycled. The content of active components in the CMA was high and it had environmentally friendly characteristics. The CMA and its solution also had a good performance in melting snow.
