What could be this?
Thanks
Dear Senthamizh,
The long chain amines may be corrosion inhibitors, and the hydrocarbons some form of perhaps grease or oil used to prevent rust.
A possibility!

Dear Dr. John,
94 % of components are identified , the rest i posted here, these component are in fragrance material. what it could be to give pleasant smell ? plant extracts? leaf extract? ................
anybody analysing plant extracts etc?????????????
Many thanks
Dear Selvan,
I am thinking on this and will report back as soon my processor generates some eigenvalues! (ideas!)
Regards,
Dr John
Dear Selvan.
Are the identifications necessarily spot on (ie correct).
Sometimes (most times!) library searches produce a series of choices.
Hydrocarbon type fragrances can be compounds like myrcene, caryophyllene, farnesene etc etc. (These are present in clove oils and hop oils etc).
Strange compounds having musky odours are the nitromusks (Musk- moskene, tibetine, ketone, xylene), these are nitroaromatics with eg t-butyl groups as aromaphores.
Some musk compounds have remarkable and unexpected structures.
Could the amines have arisen as a result of thermal decomposition of the strange "cocoamide" type compounds often used.
Might be worth a look.
Regards,
Dr John
