<p>The invention relates to an inhibitor meant for the simultaneous control of the corrosion and the crust depositions and to a process for obtaining the same. According to the invention, the inhibitor consists of 10...100 ppm of extract of beech leaves (Fagus sylvatica), depending on the composition of the treated water, providing the inhibition of the corrosion in a proportion of 80...95% as well as the blockage of the crust formation up to the temperature of 80°C. As claimed by the invention, the process consists in grinding, up to 1...5 mm, the dried beech leaves, to obtain the extract by warm treating the ground leaves with distilled water and possibly ethanol 99%, filtering the extract and additivation of 0.5 kg of glycerine and ethanol for precipitating the disaccharides, concentrating by evaporation up to 1/5...1/20 of the initial volume and bottling the concentrate in coloured bottles for protection against light.</p> |
