I found the field of Science & Technology – Other Topics very interesting. Saw the article Tribological Properties of 10-Undecenoic Acid-Derived Schiff Base Lubricant Additives published in 2021. Formula: C8H8O2, Reprint Addresses Padmaja, KV (corresponding author), CSIR Indian Inst Chem Technol, Ctr Lipid Sci & Technol, Uppal Rd, Hyderabad 500007, Telangana, India.; Padmaja, KV (corresponding author), Acad Sci & Innovat Res, New Delhi, India.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde
Four 10-undecenoic acid-based Schiff bases were synthesized by condensation of methyl 11-(2-aminoethylthio) undecanoate with various aromatic aldehydes. Synthesized compounds were characterized by spectral techniques and evaluated for their tribological and antioxidant performances in biolubricant base oil, namely epoxy 2-ethyl hexyl esters of karanja fatty acids. The tribological test results indicate that all the synthesized thioethers containing Schiff bases act as good antiwear and extreme pressure additives. A significant reduction in wear scar diameter was observed at a very low concentration (0.6 wt%), whereas, at 1 wt% concentration, weld point enhancement observed from 160 to 230 kg. Quantum chemical calculations based on density functional theory for the interactions of Schiff bases with surfaces correlated with experimental wear data. Overall, the dimethoxy-substituted phenyl ring containing Schiff base was more effective in enhancing the antiwear and extreme pressure performance of base oil, whereas dihydroxy-substituted phenyl ring containing Schiff base exhibited good antioxidant property.
Formula: C8H8O2. Welcome to talk about 123-11-5, If you have any questions, you can contact Kontham, V; Ansari, KR; Padmaja, KV or send Email.
