Abstract (English):
For the purpose of synthesis of active components of corrosion inhibitors reaction of aminomethylation of 4-Isononylphenol is studied. Aminomethylation of 4-Isononylphenol by formaldehyde both mono - and diethanol amides is studied. It is shown that reaction proceeds with intermediate education 3-oxazalidine and its N-hydroxyethyl derivative, acting as the aminomethylating agent. Reaction proceeds in the subacidic environment and is accelerated nonionic SSA. The received aminomethyl derivatives of 4-Isononylphenol are kationaktive SSA and possess rather high anticorrosive activity in compositions of corrosion inhibitors of the oil-extracting equipment.
