Abstract: In this article, studied the process of producing urea-formaldehyde compounds, i.e. dimethyl urea. The pH of the suspension was determined to be dependent on the addition of sodium hydroxide, ammonia and the ratios of carbamide to formalin. In all the pH ranges studied, the suspension was found to be very sensitive to the amount of ammonia added. Optimum process parameters of process introduction, in particular, amount of additive provides preparation of suspension with pH value 7.5-8.5 for example with the addition of 3.5 ml of ammonia, pH of suspension reaches up to 8.0 at ratio 1:1.
Key words: dimethylolurea, diffractogram, system, roentgenogram, derivatogram, nomagram, ratio, reactor, solution, fungicide, disinfectant.
