Диметилові естери НДК як складова композицій антикорозійних покрить нафтогазового обладнання

Abstract

Study and research of the main regularity in the synthesis of esters in dicarboxylic acids C₄–C₆ bases on low-molecular dicarboxylic acids with the help of methanol 80%–100% concentration in the presence of homogenic and heterogenic catalysts have been done. The optimum conditions for synthesis have been chosen and the product of synthesis have been identified. It was determined that the composition of esters in low-molecular dicarboxylic acids practically doesn’t depend upon the nature of catalyst and methanol concentration. Physico-chemical properties of the synthesized dimethyl esters in dicarboxylic acids C₄–C₆ have been determined. The obtained laboratory dimetheronol samples A and B are being tested as solvents for colour varnithes, the production as coplastificators polymer materials and as a composition component of anti-corrosive covering of the equipment for oil and gas fields too.
