Synthesis and Properties of Some Azophenol Derivatives

Abstract

Azophenol: propargyl halide: it is based on the fact that the instability of the intermediate alcohol molecule formed in the catalyst system increases due to the breaking of ionic bonds, and the nucleophilic addition reaction proceeds easily;

Propargyl ethers of azophenol are formed in high (88.6-93.1%) yields, it is proved by the fact that electron-donating solvents easily break the S-H bond in the initial components, increase the ionization energy and reaction intensity;

acetylene bond, electron pair unshared oxygen and azo groups are arranged consecutively,it was proved that azophenol 4,4'-dipropargyl diephyr with a linear structure is an effective inhibitor of corrosion protection of metals, and it was determined that the level of protection at a concentration of 0.02% is 81.0% when the aggressive environment is rN=2 - 5;

azophenol mono-, dipropargyl esters have been identified for industrial polymer materials in bright colors (orange, crimson and green), whose physico-mechanical properties do not change in different climatic conditions;

A technology for obtaining mono- and dipropargyl esters of azophenol was created.
