They are all characterized by, and distinguished from, the aliphatic or aromatic alcohols by their ready solubility in aqueous alkali. Phenols and the cresols are widely used as antiseptics and disinfectants; the cresols are contained in the wood preserving fluid, creosote. Many phenols have wide...
These phenols are characterized by particularly high germicidal and antiseptic activity. Aqueous solutions are valuable for these purposes, as are also solutions in water soluble solvents or in aqueous solutions of such solvents. Solutions in oils or fats, whether animal or vegetable, are valuable whe...
HO -OH The invention further comprises the manufacture of derivatives of polynuclear phenols which are characterized by such compounds as alpha naphthol with a melting point of 940 C. and a boiling point of 279* C. and beta naphthol with a melting point of 1220 C. and a boiling point of ...

Esters and ethers of alcadi茅nyl are prepared by telomerization of conjugated dienes with polyols, fatty alcohols, ethoxylated fatty alcohols and phenols, substituted phenols, monosaccharides and disaccharides, alkyl glycosides, alkynoqu... GRUBER Bert,WEESE Kenneth J.,HOAGLAND Steven M.,... - WO...
The phenolic lipids are a large group of natural compounds, biogenetically derived from the polyacetate pathway, i.e. they are non-isoprenoic compounds. In general, this group include one-ring molecules related to the phenol or dihydroxyphenol. The latter representatives are derivatives of 1,2...
(25 mLdichloromethaneand 9 mL methanol are approximately required)[37]. The volume oforganic solventsrequired in this work could be further decreased by automating the procedure usingflow injection analysis, and miniaturizing the SPE cartridge design, as proved previously using UiO-66 mixed-matrix ...
Scope of aryl iodides. [N2], N2detected by a gas chromatography–thermal conductivity detector at the end of the reaction. All yields are of isolated pure material. Yield in brackets:1H NMR yield calculated using dibromomethane as an internal standard. incorp., incorporated. See theSupplementar...
The particular advantage obtained according to the instant invention is to provide an active catalyst for the highly selective oxidation of aromatic carboxylic acids to phenolic compounds. Additionally, the catalysts of the invention are characterized by reduced loss or migration of copper from the catal...
The polyketoethers thus prepared from DADE under identical conditions are characterized by elemental analysis, IR spectral study, viscometric measurements in dioxane, and estimation of Mn by nonaqueous conducto-metric titration and by TGA in air. The polyketoethers are reduced by the Wolf-Krishner...
