Abstract

The article presents the results of research on the synthesis of new medium alkaline AKI-31, AKI-57 and high alkaline additives AKI-124 and AKI-134.

Additives AKI-31 and AKI-57 are calcium salts of condensation products of dodecylphenol, formaldehyde and aminoacetic (AKI-31) or p-aminobenzoic (AKI-57) acid.

Highlyalkaline additives AKI-124 and AKİ-134 are carbonated calcium salts of condensation products of dodecylphenol, formaldehyde and aminoacetic acid (AKI-124) or p-aminobenzoic acid (AKI-134).

The high performance properties of the additives have been confirmed by standard research methods. Studies have shown that the additives have high antioxidant, anticorrosive and detergent properties.

Highly alkaline additives AKI-124 and AKI-134 were studied by thermal analysis methods. It is shown that the additives are highly resistant to temperature effects.

By using highlyalkaline additives, M-10G2 motor oils have been developed, which in terms of basic performance indicators correspond to GOST 8581-92 and are on a par with the foreign analogue of Shell.
