• lithium
  • 9) Lithium amides are usually prepared in the laboratory through the addition of a titrated solution of n-butyllithium in hexanes to a solution of the amine in ether. (wikipedia.org)
  • For example, diethylmercury in the Schorigin reaction or Shorygin reaction: (C2H5)2Hg + 2 Na → 2 C2H5Na + Hg The high solubility of lithium alkoxides in hexane is the basis of a useful synthetic route: LiCH2SiMe3 + NaO-t-Bu → LiOt-Bu + NaCH2SiMe3 For some acidic organic compounds, the corresponding organosodium compounds arise by deprotonation.

  • catalyst
  • Only at a sufficiently high n-hexane hydroconversion does the catalyst with the most efficient hydrogenation function exhibit the highest dimethylbutane yield. (uva.nl)
  • This new perspective on the reported hexane hydroconversion selectivities suggests that a FAU-type zeolite catalyst with a highly efficient hydrogenation function is best suited for n-hexane hydroisomerization. (uva.nl)
  • The kinetics and mechanism of the polymerization of isobutylene (IB) using an ethylaluminum dichloride (EADC)·bis(2-chloroethyl) ether (CEE) complex as a catalyst in conjunction with tert -butyl chloride ( t -BuCl) as an initiator in hexanes at 0 °C have been previously reported. (rsc.org)
  • iPhones
  • The decision announced Wednesday comes five months after the activist groups China Labor Watch and Green America launched a petition drive calling on Apple Inc. to abandon the use of benzene and n-hexane in the production of iPhones. (cbc.ca)
  • Nevertheless, Apple decided to order its suppliers to stop using benzene and n-hexane during the final assembly of iPhones, iPads, iPods, Mac computers and various accessories. (cbc.ca)
  • In 2010-2011, Chinese workers manufacturing iPhones were reported to have suffered hexane poisoning. (wikipedia.org)
  • toluene
  • Namely, 1000 ppm n-hexane, 3000 ppm n-heptane and 1000 ppm toluene were reported to have the effect of depressing the body weight gain of rats. (wikipedia.org)
  • yield
  • Four different distillation arrangements were examined to determine major operating characteristics (yield of purified n-hexane as well as utility requirements) depending on the hexane purity desired (95% or 99%) and whether the purified n-hexane would be removed as an overhead or bottoms product. (processengr.com)
  • Analyses of a series of published n-hexane hydroisomerization product slates suggest that MAZ-type zeolites yield more dimethylbutane and less methylpentane than either FAU- or MOR-type zeolites. (uva.nl)
  • similar
  • Apple's new rules governing benzene and n-hexane hopefully will pressure other gadget makers to adopt similar policies, said Gary Cook, senior information technology analyst for environmental rights group Greenpeace. (cbc.ca)
  • Their properties are very similar to those of butanes and hexanes. (wikipedia.org)
  • Production
  • Apple is still allowing use of benzene and n-hexane during the early production phases of its products, but is lowering the maximum amount that can present in the materials used during those earlier phases of production. (cbc.ca)
  • As an additional precaution, Apple is lowering the maximum amount of benzene and n-hexane that can present in the materials used during those earlier phases of production. (cbc.ca)
  • commercial
  • PROCESS utilized its licensed commercial computer process simulation software to conduct simulations to determine the best method of generating the 95+% n-hexane by distilling the existing stream in the client's plant. (processengr.com)
  • process
  • It was determined by PROCESS that although all of these methods were, to some extent, technically capable of generating purified n-hexane, only distillation and molecular sieves appeared to offer commercially feasible methods. (processengr.com)
  • The study also determined that a proprietary mol sieve process technology offered by a particular technology provider could be capable of generating the purity of n-hexane required. (processengr.com)
  • high
  • Hexane selenol (CH3(CH2)(5)SeH) was adsorbed from gas phase in ultra-high vacuum on polycrystalline Cu and studied with synchrotron radiation based photoelectron spectroscopy (PES) and Near edge X-ray absorption fine structure spectroscopy (NEXAFS). (diva-portal.org)
