The prime example of an aromatic alcohol
is cresylic acid and its derivatives.
A mixture of an aromatic alcohol
(3 mmol), sodium nitrate (6 mmol), and [DDPA][HS[O.sub.4]] (1.2mmol) was heated with stirring at 80[degrees]C for 5-30 min in a round-bottomed flask.
The dominant features of the C k-edge spectra include: (1) quinone and diene C at 284.5 eV, (2) aryl and olefinic C at 285.2 eV, (3) unsaturated C at 286.1 eV, (4) phenolic (aromatic C connected to O group (COH) in phenols) and ketonic C (carbonyl substituted aromatic structures of quinones, phenols and ketones) at 286.7 eV, (5) aliphatic and carbonyl C (carbonyl functionalities from aromatic ketones) at 287.7 eV, (6) carboxylic C, carbonyl C in carboxylic acids, aromatic alcohols
and polysaccharide structures at 288.4 eV, (7) O-alkyl C (e.g.
As a part of our ongoing interest in one-pot procedures [31,32,36,37], which involve the design of the environmentally and economically favored one-pot reactions, our group has recently reported efficient one-pot preparation of (Z)-a-chloro-a,bunsaturated esters through chlorination/ oxidation/ Wittig olefinaation cascade.NCS and the DMSO/SO3*pyridine complex were used as the chlorinating agent and oxidant, respectively, sand activated alcohols, such as allylic alcohol, propargylic alcohol, and aromatic alcohols
, were used as starting compounds as well as alkanols .
With the continued interest in our studies to find new and improved catalysts we carried out a comparative study of Zr[O.sub.x]-MnC[O.sub.3] or Zr[O.sub.x]-[Mn.sub.2][O.sub.3] for the oxidation of primary alcohols  and it was found that the Zr[O.sub.x]-MnC[O.sub.3] was an excellent catalyst for the oxidation of primary aromatic alcohols
to corresponding aldehydes with molecular [O.sub.2].
The results showed that all secondary aromatic alcohols
were selectively oxidized into their corresponding ketones with 100% convertibility under optimized circumstances (Table 6, entries 1-6).
The stubborn polymer assortment of aromatic alcohols
known as lignin continues to be a key factor limiting the efficiency of pulp and paper production.
It is comprised of a surfactant system (including an alkox-ylated nonionic surfactant, a sulphated or sulphonated anionic surfactant; and a neutralizing co-surfactant); a thickener or mixture thereof; a chelant or mixture thereof; a solvent selected from the group consisting of ethers having from 4 to 14 carbon atoms, diethers having from 4 to 14 carbon atoms, glycols, alkoxylated glycols, alkoxylated aromatic alcohols
, aromatic alcohols
, alkoxylated aliphatic alcohols, aliphatic alcohols, C8-C14 alkyl hydrocarbons, C8-C14 cycloalkyl hydrocarbons, C8-C14 alkyl ha lohydrocarbons, C8-C14 cycloalkyl halohydrocarbons, C6-C16 glycol ethers, and mixtures thereof; and water.
Lignin, a complex polymer of aromatic alcohols
, is an integral part of the secondary cell walls of plants and some algae.
The values for aliphatic alcohols obtained during experimentation ranged from 23 to 267 g per L, and the sum of aromatic alcohols
ranged from 2,437 to 11,844 g per L.
The majority of the hawkmoth-pollinated flowers emitted spicy aromatic alcohols
and esters, as scientists had predicted, but so did a few relatives that attract other pollinators.
