Description

AKOR-1 Alkenyl ntararny acid j where alkenyl Cd-Scho (CAP-25) Comparative - the effectiveness of the proposed additive is presented in. , in tab, 1. and 2. The formation of a synergistic mixture with AKOR-1 and KAP-25 additives was established by testing 2% compositions (in terms of active components) according to a set of GOST 9.O54-75 methods by measuring conductivity and dielectric constant, Also by the method of exposure to elevated temperature and in contact with the contact of steel and copper.

The effect of the ratio of ACR-1 and CAP-25 on the protective properties of the composite ({2% -H solutions)

Table From the data table. I, 2 shows that the protective additive consisting of AKOR-1 additive to alkenyl succinic acid with the number of carbon atoms in the alkenyl radical 8-2O in the indicated ratio forms a synergistic mixture, whose protective properties when exposed to aggressive media are 2-5 times better t protective properties of the known additive AKOR-1. A protective additive is prepared by mixing the starting components at 6 ° C. The protective additive according to the invention can be used for the preservation of metal products with the introduction into mineral oils in concentrates 510 wt.% Instead of the additive AKOR-1.

Note. Additives are taken from the calculation of the component. active content
