The studies with different amines aimed to select the most rational ones as the base of the mixture by the criteria of the maximum reaction temperature, the pH value of the resulting mixture of reaction products, its viscosity under equal conditions (ambient temperature T = 25°C), the molar ratio between the base and the acid in proportions of 1.2:1, the content of acetic acid in the mixture of acids of 40%, the content of solvents of 35% of the mass of the reacting mixture showed that N-butylamine meets all the criteria. It was suggested using it for further research in exothermic reactions in developing the technology for removing paraffin deposits. Experiments using N-butylamine as a base, solvents of kerosene and xylene with a total mass of 35%, an acidic composition of acetic acid (50%) and LAS (50%), with a molar ratio between base and acid of 1.2:1, the total volume of the reacting mixture of 400 ml showed that the composition of solvents with xylene content of 10% and kerosene of 90% has the best ability to dissolve paraffin deposits (88%) than in the absence of xylene (80%). This composition of solvents also has a better state of the reaction products than in the case of a xylene content of more than 20% (no layer is formed, ARPD is not re-formed). Therefore, the composition of solvents with 10% xylene and 90% kerosene is most optimal. [ABSTRACT FROM AUTHOR] |
