ABSTRACT:
Disclosed is a process to produce paraformaldehyde prills having a low dissolution time and low concentration of insoluble formation. The insolubles are believed to lead to stickiness, tackiness, and loss of flowability of the product, loss of handling, and lead to storage problems of the final prill product. To address this problem, a concentrated formaldehyde solution is prepared having a purity ranging from 37%-99% and may be mixed with an amine additive, an amine and alcohol additive, or amine, alcohol, and caustic additive. Alternatively, the final prill may be sprayed with an amine or amine mixture stabilizer.
