The preceeding report indicated that the best method of suppressing the side reaction in the manufacture of formaldehyde from methanol was a direct spraying of cooling fluid on the bottom of catalyst layer.The problem whether or not the formaldehyde absorbed solution can be used as a cooling spray fluid has been investigated.<BR>Namely, the formaldehyde absorbed solution was applied on a pilot plant for manufacturing of 37% formaldehyde solution with a capacity 1 ton/day as a cooling fluid and studied the effect of increasing concentration of formaldehyde from a pure water. The result indicated that it was as effective as the pure water until the formladehyde content reached up to 37%. There was an agreement in experimental and theoretical yields within the variation of 1%.
