Nitration in oil
Webb12 dec. 2012 · MPO/H 2 O 2 /NO 2 −-catalyzed nitration of (9Z,11E)-CLA, even in the presence of high tyrosine concentrations, revealed that tyrosine does not compete with CLA for nitration. Moreover, the addition of a 50–400 m excess of tyrosine over CLA increased CLA nitration, most likely a consequence of reactions between tyrosyl and … Webb28 aug. 2014 · Interpreting used oil analysis.

WebbFrom time to time traces of Copper show up in used oil analysis reports ranging from a few PPM to over a 1000 PPM. Generally, high Copper levels are not a cause for concern unless other wear metals are present in unusual levels. Copper is a soft metal so it will not promote wear, abrasion, or other damage in equipment.

The term also is applied incorrectly to the different process of forming nitrate esters (−ONO2) between alcohols and nitric acid (as occurs in the synthesis of nitroglycerin). The difference between the resulting molecular structures of nitro compounds and nitrates (NO−3) is that the nitrogen atom in nitro compounds is directly bonded to … bakal 10mmWebbNachfüllen mit frischem Öl die Lebensdauer der Öl-füllung.
