• benzaldehyde
  • In a 2-l. bottle equipped with a mechanical stirrer are mixed 635 g. (800 cc., 11.0 moles) of u. s. p. acetone (Note 1) and (Note 2) , 420 g. (400 cc., 4.0 moles) of freshly distilled benzaldehyde boiling at 178-180° (shaken with dilute sodium carbonate just before distillation), and 400 cc. of water. (orgsyn.org)
  • Solvent
  • During the war the Allies needed pure acetone as a solvent for nitro-cellulose, a highly flammable compound that is the main component in gunpowder. (wikipedia.org)
  • hydrogen
  • For most hydrogen bonds, the X-H bond length of the donor increases upon hydrogen bond formation and the X-H stretching frequency exhibits a red shift in the vibration spectra (i.e. the vibration frequency decreases). (wikipedia.org)
  • However, the subtle interplay between these two effects makes prediction of blue-shifting hydrogen bonds difficult as was shown by an surprising observation of a hydrogen bonds red shift of halothane (2-bromo-2-chloro-1,1,1-trifluoroethane) upon complex formation with acetone. (wikipedia.org)
  • acetone complex the hyperconjugation and rehybridization mechanisms compensate while for typical blue shifting hydrogen bonds (e.g. fluoroform. (wikipedia.org)
  • reactions
  • This has happened in our lab before with nitric acid and dirty sinters, our supervisor is convinced that RT acetone is all you need to clean stuff (as we should be doing reactions 'properly' and not get polymer shit on our glassware in the first place). (blogspot.com)
  • In place of acetone, acetonedicarboxylic acid is known as the "synthetic equivalent" the 1,3-dicarboxylic acid groups are so-called "activating groups" to facilitate the ring forming reactions. (wikipedia.org)
  • mixture
  • Salt formation is permitted to occur until 0,0007 to 0,011 equivalent percent has taken place and the mixture is then dispersed at least in a quantity of water such that the solids content is 60 percent. (google.com)
  • ether
  • Baeyer and Villiger prepared the dimer by combining potassium persulfate in diethyl ether with acetone, under cooling. (wikipedia.org)
  • stable
  • Part 4: Formation and characterization of stable radicals from novel bis- and tris-bithiophene. (uio.no)
  • The tetrameric form of acetone peroxide, prepared under neutral conditions using a tin catalyst in the presence of a chelator or general inhibitor of radical chemistry, is reported to be more chemically stable, although still a very dangerous primary explosive. (wikipedia.org)
  • production
  • The production of acetone by acetoacetate decarboxylase-containing or clostridial bacteria was utilized in large-scale industrial syntheses in the first half of the twentieth century. (wikipedia.org)
  • However, there has been a growing interest in acetone production that is more environmentally friendly, causing a resurgence in utilizing acetoacetate decarboxylase-containing bacteria. (wikipedia.org)
  • intermediate
  • The instability of the peroxide intermediate as well as the formation of stoichiometric, low-valued acetone are the major drawbacks of this process. (rsc.org)
  • The overall hydrophobic environment of the active site plays a critical role in favoring the neutral amine form of Lys115, a key residue involved in the formation of a Schiff base intermediate. (wikipedia.org)
  • Further research led to the isolation of an active site peptide sequence and identification of the active site lysine, Lys115, that is involved in the formation of the Schiff base intermediate. (wikipedia.org)
  • chemical
  • In the 1960s, the industry replaced this process with less expensive, more efficient chemical syntheses of acetone from petroleum and petroleum derivatives. (wikipedia.org)
  • However
  • However, what our esteemed colleague did on Saturday was attempt to combine the two methods by putting a heady mix of concentrated nitric acid (horrible stuff) and acetone into a sonic bath and wash her flasks in that. (blogspot.com)
  • solution
  • Fixation is therefore quite likely if a solution of an acid dye is applied to cellulose acetate filaments immediately after their formation by dry spinning from an acetone solution of cellulose acetate. (google.com)
  • white
  • Acetone peroxide takes the form of a white crystalline powder with a distinctive bleach-like odor (when impure) and can explode if subjected to heat, friction, static electricity, strong UV radiation or shock. (wikipedia.org)
