Conclusions

  1. 1.

    A process was developed for obtaining alkyl carbametes from urea and the corresponding alcohols in the presence of an aluminosilicate catalyst.

     
  2. 2.

    Optimal regions for synthesis of methyl carbamate were determined by the Box-Wilson method of multifactor systematization.

     
  3. 3.

    The effect of various factors (temperature and length of reaction, ratio of initial reagents, space velocity of raw-material introduction, quality of the initial raw material, and length of operation of the catalyst) on the yield of methyl carbamate were studied.

     
  4. 4.

    C2-C5 alkyl carbamates were obtained in yields of 75–79% of the theoretical under the optimal conditions found for methyl carbamate.
