Acetylene alcohols and phenyl acetylene allow synthesizing the necessary substances for the chemical industry - synthetic polymers, pharmacological preparations, agricultural pesticides, defoliants, plant stimulants. We investigated the synthesis of tertiary alcohols on the base of acetylene and phenyl acetylene, the conditions for their high productivity, the structure of secondary and tertiary alcohols were determined, and confirmed by physical parameters. The refractive index of light, density, boiling point and productivity were defined. Alcohol molecules are polarized due to a shift in the density of the electron cloud towards the hydroxyl groups in secondary and tertiary alcohols. Their influence to halogen occurs through electrophilic addition. There are trans- and cis-spatial forms of halogen derivatives, which are began with the formation of the π-complex. Halogen formations are colorless liquids, and bromine formations turn into a black liquid over time. The structure of halogen
compounds is confirmed by IR and PMR spectra. The constants of halogen compounds were determined, such as light refraction, density and boiling temperature. The influence of the nature of the solvent to the output of product was established.
