Physical and chemical regularities of synthesis of monoterpenic alcohols by turpentine hydration at a catalysis ortofosforny acid are studied. Influencing of concentration of the catalyst, the water module, temperature and hydration duration on structure and quantity of received products is reviewed. Conditions of obtaining monoterpene alcohols are recommended: the concentration of catalyst aqueous solution – 40%, the temperature – 65 °C, the duration of the synthesis – 4 hours, the water module – 1 : 1, the amount of emulsifier – 0,3% by volume phosphoric acid. Crystallization a-terpineol from reaction mixtures with a high content of terpene alcohols studied. Basic physical and chemical characteristics of the products obtained are identified and their fungicidal and bactericidal activity was studied.
