Backround. Synthesis of new acetylenic alcohols on the base of local raw materials was performed, elaboration of their production with using economically-cheap, ecologically pure technology and their using as biocides of biocorrosion, ionites and herbicides in agriculture is an actual problem. Purpose. Synthesis of new aromatical acetylene alcohols obtained on the base of phenylacetylene and some cyclical ketones. Investigation of influence of high-basical system on duration of reaction and yields of products and row of activity of ketones in synthesis on their base acetylenic alcohols. Methotodlogy. Homogeneous and heterogeneous catalyst, extraction, separation, spectroscopy and chromatography analysis, quantitative-chemical methods, physic-chemical method of investigations. Originality. For the first time new acetylenic alcohols have been synthesized by alkylation of some cyclic ketones by phenylacetylene in the presence of high-base catalytical system. Influence of nature of catalytical system on yield of obtained products has been discussed. Biological activity of some acetylenic alcohols has been investigated. Findings. New acetylene alcohols by interaction of investigated ketones with phenylacetylene have been synthesized. Structure, purity and composition of synthesized compounds of obtained compound have been determined; distribution of electronic density and dynamical parameters have been calculated of quantum-chemical methods. Highlights: * new acetylenic alcohols on the base of local raw-materials were synthesized; * composition, purity and structure of acetylenic alcohols were investigated; * using of obtained compounds has been determined
