Practice working with your Learning By Modeling software Construct molecular models of ethane ethylene and acetylene and compare them with respect to their geometry bond angles and C—H and C—C bond distances... [Pg.56]

Acyclic Compounds. Different conformations of acyclic compounds are best viewed by construction of ball-and-stick molecules or by use of Newman projections (see Fig. 1.2). Both types of representations are shown for ethane. Atoms or groups that are attached at opposite ends of a single bond should be viewed along the bond axis. If two atoms or groups attached at opposite ends of the bond appear one directly behind the other, these atoms or groups are described as eclipsed. That portion of the molecule is described as being in the eclipsed conformation. If not eclipsed, the atoms... [Pg.39]

Dichlorofluoro-ethane (CCI2FCH5) The leading substitute blowing agent for CFC-11 in rigid foam insulation applications such as construction (commercial, residential, and public), appliances, and transport vehicles. [Pg.322]

Difluorochloro-ethane (CH5CCIF2) An effective replacement for CFC-12 in rigid polyurethane, polystyrene, and polyethylene foam insulation applications. Uses include both residential and commercial construction and process piping. [Pg.322]

The first step in the production of synthesis gas is to treat natural gas to remove hydrogen sulfide. The purified gas is then mixed with steam and introduced to the first reactor (primary reformer). The reactor is constructed from vertical stainless steel tubes lined in a refractory furnace. The steam to natural gas ratio varies from 4-5 depending on natural gas composition (natural gas may contain ethane and heavier hydrocarbons) and the pressure used. [Pg.140]

The interaction pattern is exactly the same for ethane. Instead of constructing a pair of [Pg.14]

The a orbitals of ethane will not, of course, remain pure bonding orbital and the phase bonding combination will mix together. The manner in which this mixing occurs has been illustrated for ethylene. The resulting ethane orbitals have been constructed, by a different technique, in the previous section. [Pg.19]

The ethane molecule can be constructed by union of two pyramidal methyl radical fragments. The interaction diagram is shown in Fig. 16 and the key stabilizing orbital interactions are depicted below. [Pg.54]

The reaction appears to be general and the additions are regiospecific and stereoselective. The product from the reaction with 2-propanol has been used for the synthesis of cis-chrysanthemic acid,8 and the product with methanol has been used for the construction of novel 2, 3 -dideoxy-3 -hydroxymethylnucleosides.9 In addition, ethane-1,2-diol provides the expected photoadduct as a 1 1 mixture of the two possible diastereoisomers, and these can be easily separated as their acetonides, to provide compounds with three contiguous chiral centers emanating from furan-ones with only one chiral center.9 More recently, we have shown that photoinduced-... [Pg.219]

Considerable attention has been given to the construction of heterocyclic bridges of dihetarylethenes based on ethane-1,2-dione, 2-hydroxyethan-l-one, and 2-chloroethan-l-one derivatives. In many cases, readily available 2,5-dimethylthiophene is used as the starting compound. 2-Hydroxy-l,2-bis(2,5-dimethyl-3-thienyl)ethan-l-one 213, one of the key substrates, was synthesized according to Scheme 62 (01IZV113). [Pg.43]

A major current refinery-petrochemical project is under construction for Saudi Aramco-Sumitomo Chemical at their Rabigh, KSA site. In conjunction with our JGC partner we have linked the upstream refinery expansion to a combined mega-DCC unit and mega-ethane steam cracker. Corresponding production rates are 1500 kta ethylene/950 kta propylene. The corresponding integrated layout is shown below in Figure 8.2. [Pg.125]

A process in your company generates waste gases that need to be vented to the outside at a rate of 1 m3 per hour. In particular, you must be sure that the 1,1,2,2-tetrachloroethane present at 100 ppmv (i.e., 100 x 10 6 m3 of 1,1,2,2-tetrachloro-ethane vapor per m3 of total gas) will be removed from the gas-stream before discharge. Someone suggests you construct an adsorbent column filled with alumina (A1203) and run the gas through that column to capture the 1,1,2,2-tetrachloroet-hane. [Pg.452]
