Essay

The dissertation work contains results of complex experimental and theoretical study of influence of ozone, initial and finished of products on corrozion-electrochemical behaviour of constructional materials in processes ozone synthesis of pyridine N-оxide and of pyridinecarbon acids in neutral, acetic and sulfuric environments. The basic laws of corrosion of aluminium, carbonaceous , manganese containinq and some chromnickel steels in phosphatic рН 7 buffer, 5 % -s' acetic and 70% -s' sulfuric acid at presence of ozone, homologues of pyridine them N-оxides and of niacins are established. In conditions of industrial synthesis of a dipicolinic acid in a acetic solution, 4-methylpyridin-N-оxide in the phosphatic buffer, and also of preparatic synthesis of a niacin are carried out volt-ampere and of massmetric research of various constructional materials and the recommendations concerning their use for manufacturing of reactors of processes ozonization are submitted.
