10,11) Of these compounds, guaiacol, m-cresol
and 4-methylguaiacol have the lowest aroma thresholds of 23 [micro]g/L, 20 [micro]g/L and 30 [micro]g/L (BET, or best estimate threshold), respectively, emphasizing why they are considered the primary chemicals associated with smoke taint.
The occurrence of m-cresol
in the environment is mainly related to use this compound in cosmetic, fragrance, disinfectant, explosive and pesticide production .
T he synthesized PPy was found to be completely soluble in DMSO DMF T HF chloroform and m-cresol
Dissolves only m-cresol
of 100% concentration at 139oC in 5 minutes.
To measure the degree of crosslinking in a nylon, the gel content can be measured using an extraction method with m-cresol
as the solvent.
The results showed eight major peaks in phenolic fraction chromatograms: guaiacol, 4-methylguaiacol, phenol + o-cresol, 4-ethylguaiacol, p-cresol, m-cresol
, 2,3-xylenol, and syringol.
On the other hand, organic solvents such as chloroform, xylene and m-cresol
are necessary for solution processing of polyaniline and among these organic solvents, m-cresol
can also play as a secondary dopant for polyaniline and extend conformation (11).
is used as a solvent to investigate viscosity number of PA12.

LRAPA's permit to Baxter lets the firm emit up to a total of 5,320 pounds a year of federally listed hazardous chemicals such as phenol, naphthalene, c-cresol, m-cresol
and dibenzofuran - all used in the process of treating wood.
Summary: The synthesis of a new polymeric resin [poly 4,4'-(naphthyl bis(oxy))bisbenzaldehyde ethylenediimine] (PNBOBen) by polymerization from dialdehyde 4,4'-naphthylbis(oxy) bisbenzaldehyde with ethylenediamine in m-cresol
is described The synthesized Schiff base polymer (PNBOBen) was characterized by elemental microanalysis, FT-IR and 1H-NMR spectroscopy.
UV--vis spectra of polymer solution in m-cresol
were recorded using Hitachi-U3210 spectrophotometer in the range of 300-900 nm.
