Process for preparing stable aqueous suspensions of formaldehyde |
| abstract |
ABSTRACT OF THE DISCLOSURE: Stable aqueous suspensions of formaldehyde of at least 40% by weight concentration are prepared by heating aqueous formaldehyde solutions to a temperature of from about 40°C to about 80°C in the presence of stabilizing agents, in the presence or absence of methanol, and at a pH in the range of from about 0.5 to 1.5 or about 6.0 to about 8.0, cooling the mass to a temperature of from about 10°C to about 40°C, and adjusting the pH thereof to about 3.0 to 4.0, the concentration of formaldehyde in the starting aqueous solution ranging from about 40% to 60% by weight. |
