  • Alkane derivatives can be formed by substituting an alkyl group for one of the hydrogens. (gsu.edu)
  • Almost an unlimited number of derivatives can be made from the alkanes since any hydrogen can be substituted by an alkyl group , a halide, etc. (gsu.edu)
  • If the substituent is an alkyl group, then the derivative will have the same empirical formula as a larger alkane, so the empirical formula for an organic compound is insufficient to identify it. (gsu.edu)
  • The invention also relates to a process for the manufacture of the material and a process for the dehydrogenation of alkanes by using the material according to the invention. (patents.com)
  • In the present study, insights into alkane cracking and dehydrogenation on [GaH] 2+ , Zn 2+ and other Group 13 hydrides exchanged into MFI are developed for the activation of C 2 -C 4 alkanes. (aiche.org)
  • The name is formed by changing the suffix -e of the parent alkane to -al , so that HCHO is named methanal , and CH 3 CH 2 CH 2 CHO is named butanal . (wikipedia.org)
  • Here's the thing: This stuff (C 12 H 12 ) comes in 10 forms, called isomers . (wired.com)
  • the composition has a film forming binder solids content of about 30-70% by weight contains about (A) 50-80% by weight, based on the weight of the binder, of a hydroxy functional acrylic polymer of polymerized. (google.com.au)
  • Nonane is the lightest alkane to have a flash point above 25 °C, and is not classified as dangerously flammable . (wikipedia.org)
  • The IUPAC nomenclature (systematic way of naming compounds) for alkanes is based on identifying hydrocarbon chains. (wikipedia.org)
  • That cyclo prefix means that unlike standard alkanes, which come in chains, this one's a ring. (wired.com)
  • Alkanes can be either in straight chains, like this, you see and all the ends of these little lines are going to be hydrogen or it can be branched. (brightstorm.com)
  • Diethyl ether is also extremely flammable, especially in the vapor form. (angelo.edu)
  • RO 2 H-shift rate coefficients via transition states involving six- and seven-membered rings (1,5 and 1,6 H-shifts, respectively) of α-OH hydrogens (HOC-H) formed in this system are of order 0.1 s −1 at 296 K, while the 1,4 H-shift is calculated to be orders of magnitude slower. (pnas.org)
  • The polymers formed are called polyacetylenes and show semiconducting properties. (differencebetween.net)
  • Parenterally administrable oil-in-water emulsions formed from nutritive oils, such as soybean and sunflower oils, are improved first by treating the nutritive oil with silicic acid to remove undesirable components such as peroxides, pigments, thermal and oxidative decomposition products, certain unsaponifiable matter such as sterols, and polymers. (google.ca)
  • A new C-C bond between HMF (or furfural ) and acetone formed through aldol condensation , resulting in a C 13 -C 15 molecule fraction. (rsc.org)
  • Termination - when two radicals combine to form a molecule Br radical + Br radical = Bromine etc. (prezi.com)
  • The analysis of catalytic partial oxidation of light alkanes indicates that processes involving this group proceed via the formation and consecutive transformations of free radicals. (brillonline.com)
  • An approach to design a complex catalytic system for efficient alkane partial oxidation based on separation of zones where free radicals are formed and where they are transformed into desired products is suggested and examples of its implementation are presented. (brillonline.com)
  • Initiation - when free radicals are formed 2. (prezi.com)
  • The boronic esterterminated alkane thiol (BOR-Capped) was chemisorbed onto gold substrates. (diva-portal.org)
