The paper proposes a reconstruction of the distillation of caprolactam for more complete removal of water from the finished product, removing the droplet phase during the process in thin-film evaporators, will improve the final product performance by eliminating the inappropriate indicators alkali content and the optical density of the final product and to ensure its stable high quality. The relevance of the work presented directions for improving the process of production of caprolactam – raw ingredient for the preparation of polymeric materials used in various sectors of the economy. Describes the causes affecting the quality characteristics of the finished products produced from caprolactam. the implementation the liquid distributor and the centrifugal separator would reduce 5 – 6 times droplet entrainment to ensure complete removal of moisture from the final product, will reduce the alkali content in the final product, reduce the rate of optical density and thus bring trademark caprolactam by indicators «alkalinity» and «optical density» to the level of the highest quality product.

The use of oxygenates as a gasoline blend is one of production methods for high octane gasoline and reduction of harmful compounds amount in exhaust gas. Distillation curves are presented for single monohydroxy alcohols and gasoline mixtures containing 3- 15% by volume of ethanol, 1-butanol and i-butanol (2-methyl-1-propanol) which can be obtained from renewable sources. The influence of various concentrations of these alcohols on the distillation characteristics of base gasoline were investigated. Most alcohols form mixtures with gasoline exhibiting near-azeotropic behavior near its boiling point that significantly affect the shape of the distillation curves. In addition, distillation curves for a variety of dual-alcohol blends are presented, containing 10-20% by volume of two alcohols.
