WAY TO PRODUCE A STABLE WATER SUSPENSION OF FORMALDEHYDE AND PRODUCTS OBTAINED THEREOF |
| abstract |
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 DEG C. to about 80 DEG 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 DEG C. to about 40 DEG C., and adjusting the pH thereof to about 3.0 to 4.0. |
