Abstract
In aims to preserve environment European Economic Community pass the bill – REACH (Registration, Evaluation and Authorisation of CHemicals), which directed to achievement in europe countrys of three fundamental tasks: economical (industrial competition and advances in new technological productivity in chemical industry), social (protection of health and work of population) and guard of nature.

Abstract
Different ecologi-economical methods of waste recycling of vinyl chloride production have been considered. The most perspective method now represents a method of catalytic hydrodechlorination. The method differs by low investment costs and expenditures for waste-handling

Abstract
Recombinant chimeric constructions RTA-DHFR and RTВ-DHFR consisting of ricin Aand B-subunits genes (RTA and RTB) and dihydrofolate reductase (DHFR) gene were cloned and expressed in Escheriсhia coli. Antigenic properties of RTA and RTB retained in chimeric proteins RTA-DHFR and RTВ-DHFR.

Abstract
A tormentil (Tormentilla erecta L.) composition for litholysis of urinary calculi of various types has been developed. The suggested composition allows to prevent precipitation of Ksidifon and to keep its high complexing ability.

Abstract
New criterion of heat consumption calculation in processes of distillatory separation of liquid blends is suggested. Quantitative estimation of separation quality which is taking into account the criterion is brought out. Internal energy-saving mechanism in processes of distillatory is analyzed. Methods of energy-saving in processes of distillation of binary mixtures are suggested.

Abstract
A method is suggested to process overlapping chromatographic peaks with the use of a mathematical model of the chromatographic column. The method enables determining the composition of the mixture to be analyzed even in case of completely overlapping peaks.

Abstract
The kinetics of the interface layer growth was considered for the case of interaction of oleic acid with alkali. The temperature dependence of the microemulsion growth was studied. Effective activation energies of complicated heterogenic processes were determined.

Abstract
With the use of the problem-oriented complex “CHEMCAD 5.2.0” we have carried out evaluation of parameters of Wilson and NRTL models for biazeotropic systems butyl propionate – propionic acid and butyl butyrate – butyric acid at different pressures and mathematical simulation of vapour–liquid equilibria of binary systems. We have obtained a satisfactory description of the biazeotropy.

Abstract
It is done the analysis of the effectiveness of usage of a calorific pump with a closed cycle on the working substance in the process of antielectric crystallization. It is shown that the usage of the calorific pump allows decreasing significantly power inputs for realization of the studied process.

Abstract
A series of trans-2-(substituted amino)-cyclohehyl esters have been synthesized and examined for pharmacological activity. Significant responses have been noted with these compounds as ant arrhythmic substances.
