FIELD: chemistry.
SUBSTANCE: method of obtaining acid corrosion inhibitor based on cyclic aminoamides includes interaction of individual amines and/or polyamines with polyethylene terephthalate and chloroparaffin with weight ratio of initial reagents 0.4÷2.5:1:0.5÷2.5 respectively at temperature 110-125°C for 2.0-4.5 h with further introduction of urotropine in amount (0.07÷0.37) mol and hydrochloric acid into products of synthesis at temperature 50-60°C with further mixing.
EFFECT: extension of raw material base and simplification of technology of inhibitor manufacturing.
