In this article, various chemicals like phenol, anisole
, naphthols, benzoic acid, and phenol-like alcohols were employed as the MAO modifiers to tune the oligomerization activity and product distribution of the BIP-Fe catalyst.
Caption: Figure 6: Free radical scavenging activity histogram of AgNP and BHA (butylated hydroxy anisole
) shows the quenching efficacy of DPPH radical at different [micro]g/mL.
Traps were baited with acetoin, anisole
, benzaldehyde, 1,4-DMB, and aged yeast.
These qualifying fuels include (from an octane perspective) methanol, ethanol, 2-butanol, isobutanol, diisobutylene, the furan mixture, cyclopentanone, and anisole
. While 1-butanol, 2-methyl-l-butanol, butyl acetate, and 2,4-dimethyl-3-pentanone do not appear to have adequate blending RON, the esters and ketones in general do not appear to offer adequate octane sensitivity.
SD= standard deviation, BHT= butylated hydroxyl toluene; BHA= butylated hydroxyl anisole
; SLE= sugarcane leaf extract.
The used solvents were as follows: tetrahydrofuran (THF), 1,4-dioxane (D), toluene (T), anisole
(An), and diphenyl ether (DPE).
What's new: First cooperage in the world to offer full testing of all anisole
and haloanisoles in completed barrels to avoid TCA.
Apart from this, several synthetic antioxidants such as butylated hydroxyl anisole
(BHA), butylated hydroxyl toluene (BHT), Propylgallate (PG) and tertiary butyl hydroquinone (TBHQ) are commercially available.

Interestingly, desorption atmospheric pressure photoionization-mass spectrometry (DAPPI-MS) in negative ion mode was applied successfully for analysis of TBBP-A in circuit board and orange peel samples using anisole
as spraying solvent.
Because of the probable toxic effects of synthetic antioxidants like BHA (butylated hydroxyl anisole
) and BHT (butylated hydroxyl toluene) and natural antioxidants especially from plant gained major attention and importance towards treatment of various free-radical-related diseases such as cancer, asthma, atherosclerosis, arthritis, aging, and autoimmune disorders, several stress-related diseases including cataracts, cognitive dysfunction, myocardial infarction, and diabetes, and several cardiovascular and neurodegenerative diseases [6, 7].
