| titleOfInvention | STABILIZED, PULVERED FORMALDEHYDE |
| abstract | According to an aspect of the invention, a polymerized form of formaldehyde is available in granular form containing a polymerized form of formaldehyde, such as paraformaldehyde, a buffer, such as sodium phosphate dibasic anhydrous, and a stabilizer, such as hydroxymethyl cellulose, or hydroxypropyl methyl cellulose. When added to an aqueous solvent, the paraformaldehyde can dissolve in alkaline solution, and depolymerizes into a formaldehyde solution containing a stabilizer. Optionally a second member of the buffer pair or another buffer or pH adjuster can be used. The stabilized depolymerized formaldehyde solution is then ready for use, or can be modified by addition of other substances, such as sodium phosphate monobasic monohydrate. Additionally, an additional buffer may be included in the granular mixture to increase the rate at which the solid dissolves and depolymerizes. |
