INTRODUCTION
The search for highly effective low-toxic biologically active compounds based on them is constantly ongoing, as can be judged by a large number of publications in the world scientific and patent literature. Syntheses of new compounds based on derivatives of substituted cyclic, aromatic saturated and unsaturated alcohols, as well as ferrocene-containing phenols and isocyanates, as well as their practical application, have broad prospects in solving the priority tasks of development, primarily in the chemical, pharmaceutical industries for the production of biological products, agriculture, and as well as the entire national economy and the growth of the well-being of the people of the Republic of Uzbekistan.
Experimental methods. The synthesis of N1N1 - hexamethylene bis [(cyclohexanoloyl) carbamate] is carried out in a batch apparatus. The duration of the operation, i.e. the time from the beginning of the loading of the initial substances of

the previous operation to the beginning of the loading of the initial substances of the subsequent operation, is the sum of the durations of the individual stages. these operations are as follows: preparation of raw materials:
Loading cyclohexanol, hexane - 1,6 - diisocyanate, catalyst and solvent Mixing, chemical conversion of raw materials, removal of reaction heat = S preparation of the reaction mixture and isolation of the product: S reaction mass cooling S reaction mass unloading S drying, crushing and screening Operation duration:
The duration of the reaction apparatus during the operation is less than the total duration of the operation.
