A known method of protection is oil "corrosion protection equipment" using HHritdnTopOiB. For the purpose of expanding the range of effects of effective HNPi-Bitaro (B, according to the proposed method, argallo-1 mshaloalkoxysil is used as the last formula of the general formula R (CH2) ,, Si (OC2H5) 3, where R HsN -, CeHsNH - , (C2H5) 2N -, I2CCCHN2) bNN -, H2NC2H4NHC2H4NH-; Clause 1 or 3. These compounds can be used in a wide} H1, les, tempered) mode, they have a defoaming effect and are stable for a long time: for time. ISPITA1N1IJ compounds as carbonium steel nbit.biters were carried out in water-borne corrosive medium, tishkchnoy for oil extraction and oil refining, w in a two-phase system of imitation water, iodine, and conductive lines and pipelines. important or waste waters released during the dehydration and desalting of oil. its central concentration is 100-500 mg / l, which is taken from the heat exchange1 of the oil refinery, and at a temperature of 20-80 ° C has a protective effect, a range of 70-97%. Example 2: The compound H2NC2H4NHC2H4NH (CH2) C5 (OC2Hs) 3, under the same conditions as in Example 1, has a protective effect of 60-90%. PRI. M R 3. Compound H2NC2H4NHC2H4NHCH2Si (OC2H5) 3 at a concentration of 100 mg / l in water containing 2 g / l of oil at a temperature of 50 ° C has a 100% protective effect. Example 4. Saedinance (H2NC2H4NHC2H4NH (CH2) 3Si (OC2H5) 3 npai) with the same conditions as in Example 3, and has 96% -floe protective action. Inventory Method of protection against corrosion and oil | with the use of an inhibitor, characterized in that, in order to expand the aosortement of inhibitors, organoaminoalkoxysilapes of the general formula R (CH2) "Si (OC2Hs) 3, where R H2N -, CeHsNH -, (C2H5) 2N -, -, H2N (CH2) bMN -, H2NC2H4NHC2H4NH -; n 1 or 3.
