Abstract
This invention refers to chemical industry, in particular to process for manufacture of paraformaldehyde and can be used for manufacture of the final product with 80-83% purity. Technical result is to obtain paraformaldehyde is not characterized with adhesiveness. The method provides for preparing concentrated solution of formaldehyde, mixing catalyst up to receiving the homegenious mixture, pouring the mixture heated up to 80-100°C on to the conveyor belt, transporting the heated mixture from the first to the second heated areas, the temperature being preserved in the first area from 70°C to 90°C, and in the second area-from 25°C to 35°C. 1 fig.
