• Mechi bora ya maktaba: 3-Ethoxyphenol #392 | mechi 0.0%

• Kikwazo kinachoongoza cha maktaba hakiwezi kutibiwa kama kitambulisho cha kuaminika kwa sababu kufanana kwake kumeripotiwa ni 0.000 na wagombea wengine wa juu pia wako kwa 0.000.
• Wigo una bendi wazi ya kabonili katika 1728 cm-1, ambayo inapunguza uungwaji mkono wa kugawa sampuli haswa kama 3-Ethoxyphenol.
• Bado haijulikani kama sifa za O-H zinatokana na kiwanja asilia chenye hidroksili, unyevu uliofyonzwa, hidroksili isokaboni, au mchanganyiko.
• Ushahidi uliopo hautofautishi kwa ujasiri kati ya kiwanja kidogo cha kikaboni chenye oksijeni, nyongeza iliyooksidishwa, au nyenzo ya polimeri yenye oksijeni.
• Tabia ya kunukia au kukosa kujaa haitoshi hapa kuthibitisha kiwanja cha fenoliki haswa.

Hatua zinazofuata zilizopendekezwa: Repeat the FTIR after careful drying or mild heating under vacuum or dry nitrogen to test whether the high-wavenumber O-H features decrease, which would help separate absorbed moisture from intrinsic hydroxyl groups. Inspect the sample with ATR-FTIR and, if possible, compare replicate spots to determine whether the spectrum reflects a homogeneous material or a surface mixture. Use complementary analysis such as GC-MS for volatile or extractable components, or Py-GC-MS if the sample may be polymeric, to determine whether a discrete oxygenated compound or a polymer/additive mixture is present. If distinguishing ester versus phenolic or ether functionality is important, examine the 1800-1500 cm-1 and 1300-1000 cm-1 regions at higher signal quality and compare against targeted reference spectra for oxygenated organics with carbonyl and C-O groups.
