  • enough phenol
  • Interesting, we distill enough phenol for over 6 months (eg. (bio.net)
  • By the time the plot was discontinued, it had succeeded in diverting enough phenol, according to Albert, to make about 4.5 million pounds of explosives. (wikipedia.org)
  • The public pressure soon forced Schweitzer and Edison to end the phenol deal, with the embarrassed Edison subsequently sending his excess phenol to the U.S. military, but by that time the deal had netted the plotters over two million dollars and there was already enough phenol to keep Bayer's aspirin plant running. (wikipedia.org)
  • cyclic
  • In several sources, the structure of phenol red is shown with the sulfur atom being part of a cyclic group, similar to the structure of phenolphthalein. (wikipedia.org)
  • compound
  • It is a measure of the bactericidal activity of a chemical compound in relation to phenol. (wikipedia.org)
  • To calculate phenol coefficient, the concentration of phenol at which the compound kills the test organism in 10 minutes, but not in 5 minutes, is divided by the concentration of the test compound that kills the organism under the same conditions (or, probably more common, dividing the dilution factor at which the tested substance shows activity by the dilution factor at which phenol shows comparable activity).

  • Chemical
  • PHENOL International Programme on Chemical Safety Poisons Information Monograph 412 Chemical 1. (inchem.org)
  • Phenol extraction is a processing technology used to prepare phenols as raw materials, compounds or additives for industrial wood processing and for chemical industries. (wikipedia.org)
  • Schweitzer, with money funneled from Germany through Albert, set up a contract for a front company called the Chemical Exchange Association to buy all of Edison's excess phenol. (wikipedia.org)
  • Substance
  • When listed numerically, the figure expressing the disinfecting power of a substance by relating it to the disinfecting power of phenol may be a function of the standardized test performed. (wikipedia.org)
  • clinical
  • Auramine phenol stain is a stain used in clinical microbiology and histology to identify tuberculosis mycobacteria. (wikipedia.org)
  • water
  • In ordinary language it may be called a solution of water in phenol . (dictionary.com)
  • The second is that phenol has a density of 1.07 g/cm3, which is higher than the density of water (1.00 g/cm3). (wikipedia.org)
  • High levels of bromine can convert phenol red to bromophenol red (dibromophenolsulfonephthalein, whose lowered pKa results in an indicator with a range shifted in the acidic direction - water at pH 6.8 will appear to test at 7.5). (wikipedia.org)
  • Phenol, formaldehyde, water and catalyst are mixed in the desired amount, depending on the resin to be formed, and are then heated. (wikipedia.org)
  • Being thermosets, hydroxymethyl phenols will crosslink on heating to around 120 °C to form methylene and methyl ether bridges through the elimination of water molecules. (wikipedia.org)
  • tissue
  • Phenol exerts a marked corrosive action on any tissue of contact when ingested, inhaled or after skin exposure. (inchem.org)
  • Since the color of phenol red can interfere with some spectrophotometric and fluorescent assays, many types of tissue culture media are also available without phenol red. (wikipedia.org)
  • composition
  • Phenol-Explorer is a comprehensive database on natural phenols and polyphenols including food composition, food processing, and polyphenol metabolites in human and experimental animals. (wikipedia.org)
  • species
  • There are two types of auramine phenol stains, 1 and 2 to stain mycobacterium species and cryptosporidium respectively. (wikipedia.org)
  • The reactive species is the phenoxide anion (C6H5O−) formed by deprotonation of phenol. (wikipedia.org)
  • careful
  • Schweitzer sold the remainder of the phenol at a considerable profit, being careful to distribute it to only non-war-related industries. (wikipedia.org)
  • indicator
  • i.e. the phenol red can be seen as an indicator of the process. (bio.net)
  • Phenol red, sometimes labelled with a different name, such as "Guardex Solution #2", is used as a pH indicator in home swimming pool test kits. (wikipedia.org)
  • Group
  • The simplest phenol, consisting of a benzene ring attached to a hydroxyl group (OH). (dictionary.com)
  • The initial reaction in all cases involves the formation of a hydroxymethyl phenol: HOC6H5 + CH2O → HOC6H4CH2OH The hydroxymethyl group is capable of reacting with either another free ortho or para site, or with another hydroxymethyl group. (wikipedia.org)
  • known
  • One reacts phenol and formaldehyde directly to produce a thermosetting network polymer, while the other restricts the formaldehyde to produce a prepolymer known as novolac which can be moulded and then cured with the addition of more formaldehyde and heat. (wikipedia.org)
  • test
  • there never was any phenol in the test tube. (dictionary.com)
  • The Chick-Martin test was then widely used until replaced by more suitable tests not reliant on phenol and reflecting the conditions in which modern disinfectants are used. (wikipedia.org)
  • The test is based on the fact that phenol red is excreted almost entirely in the urine. (wikipedia.org)
  • medicine
  • Schweitzer defended his actions, arguing that making medicine and disinfectants was a better use of the phenol than making weapons. (wikipedia.org)
  • together
  • When the molar ratio of formaldehyde:phenol reaches one, in theory every phenol is linked together via methylene bridges, generating one single molecule, and the system is entirely crosslinked. (wikipedia.org)
  • small
  • A small amount of phenol red added to this growth medium will have a pink-red color under normal conditions. (wikipedia.org)
