Abstract (English):
For the purpose of synthesis of active components of corrosion inhibitors reaction of sulphomethylation of 4-Isononylphenol is studied. It is shown that condensation of 4-Isononylphenol with formaldehyde and sodium sulfite with its formation of the sulfomethyl derivatives proceeds only in the alkaline environment, in the presence of water and nonionic SSA. The obtained data testify that process passes through intermediate formation of 2-hydroxymethyl-4-Isononylphenol turning in the alkaline environment in 2-methylydene-4-Isononyl-3,5-dienecyclohexane. The last reacts about sodium sulphonate anion with education 2-(sodium I sulfonato-marked) – 4-Isononylphenol. The received sulfomethyl derivatives of 4-Isononylphenol are anionaktive SSA and possess rather high anticorrosive activity in compositions of corrosion inhibitors of the oil-extracting equipment.
