Abstract

Molasses is a natural bioactive material from sugar industry, containing a lot of organic acids such as formic, lactic, acetic. Interaction between formic acid and urea is very important in the production fertilizers with bioactive materials. Interaction between urea and formic acid was found to occur at different ratios of the components. CO(NH2)2·HCOOH and CO(NH2)2·2HCOOH were obtained when the molar ratio was equal 1 : 1 and 1 : 2, respectively.

Crystallization of CO(NH2)2·HCOOH lasts 15 days, but CO(NH2)2·2HCOOH crystallization duration is equal to 7 days.

Urea solubility increased when at higher concentrations of formic acid.

The various structures of urea formiates was confirmed by different instrumental methods.

The urea and formic acid interaction products are stable at room temperature.
