The production process consists of two steps, as shown in Figure 7. In the first step, urea reacts with an aqueous solution of formaldehyde under slightly basic conditions to form several different hydroxymethylated ureas. The degree of substitution depends on the ratio of formaldehyde to urea as well as on other reaction conditions.
