Investigation of nitrogen-, sulfur-, and phosphorus-containing derivatives of o-hydroxyalkylthiophenols as lubricating oil additives

“…At the same time, methylaminomethyl-, diethylaminomethyl-, dibutylaminomethyl naphthenate for 25 h at 140°C (lead plates) [15].…”

“…The familiar commercial additive IKhP-21 was used as a reference for comparison. The test results (Table 2) In order to determine the dependence of anticorrosion properties on the composition and structure, the synthesized aminolmethyl derivatives of o-hydroxyalkyl thiophenols were investigated as a component of the M-11 diesel oil by the more stringent NAMI method (GOST 20502-75) in the presence of 0.02% of copper naphthenate for 25 h at 140°C (lead plates) [15]. The test results are furnished in Table 3.…”

“…The tests were performed in keeping with the system of comprehensive investigation and evaluation of the protective properties of oils in a humidity chamber, in sea water, and under the action of hydrobromic acid by methods governed by GOST 9.054-74 and 9.041-74. The test results showed that aminomethyl derivatives of 2-hydroxyalkyl thiophenols are fairly effective protective additives [16][17][18][19][20][21][22][23][24].…”
