Summary: Experimental data on the removal of arsenic compounds (V) with water sample with a starting concentration of 500 mg / dm3. Considered coagulation and sorption methods of removal of arsenic compounds (V). A combined method of treatment, which in the first stage will include coagulation, and the final - sorption.
Key words: water, coagulation, sorption, activated carbon.
Summary: Solvent sublation is a combined method that includes advantages of ionic flotation and liquid extraction. This is a process in which flotation product (sublate) concentrates in a thin layer of organic liquid, which is located on the surface of aqueous phase. The research of zinc ions by solvent subltation from model solutions allowed to determine rational conditions of process: pH 7, molar ratio of Zn2+:surfactant = 1:2, the volume of organic phase 5 cm3. Under these conditions removal ratio of zinc ions into isoamyl alcohol is 95%.
Key words: zinc, solvent sublation, removal ratio, sublat.
Summary: The acid-catalyzed interaction of olefins with aldehydes has been studied as one of the main methods for the preparation of substituted 1,3-dioxanes. The main methods of obtaining both thermal heating and microwave irradiation are considered. It is found that during the Prince reaction under microwave heating conditions, the reaction time is significantly shortened, but the composition of the products does not change.
Key words: 1,3-dioxanes, olefins, aldehydes, acid catalysis, microwave radiation.

Abstract: Substituted cyclopropanes, is one of the Central places in modern organic chemistry, since these compounds and their derivatives have valuable properties and are widely used in various fields of science and technology. The paper describes methods of obtaining substituted cyclopropanes, as well as different ways of their transformation.
Key words: gem.-dihalogentcyclopropanes, cyclopropanation, dihalogencarbenes.
