dimerizes propylene to isohexenes in the presence of a nickel-based Ziegler-Natta catalyst Codimerization of propylene with butenes is also possible Dimersol E is designed to cooligomerize ethylene with residual propylene found in FCC unit offgas 89 Industrial dimerization of n-butenes to octenes is carried out with a soluble nickel catalyst (Dimersol X process)90,91 or in the presence of a solid catalyst (Huels Octol process)92,93 In both cases n-octenes and methylheptenes are the predominant products The solid catalyst developed jointly by Huels and UOP is highly selective to produce normal and monobranched C8-C 12 olefins These are transformed to C9-C 13 alcohols through hydroformylation and hydrogenation and used as plasticizers 93 Huels, however, developed two catalysts, and one of these can produce more highly branched C 8 alkenes for gasoline blending 94 The feedstocks in the process are raffinate II or raffinate III.

1. Create a new swatch with the appearance you want. Use the color sliders to do this. 2. Double-click the newly created swatch. This opens the Swatch Options dialog box. 3. Change the Swatch type from Process to Spot. Now, when you use that swatch as a fill or stroke, Illustrator considers it a spot color when it comes time to print.

The former is a steam cracker C4 cut rich in n-butylenes (70-80%) after the removal of I,3-butadiene (by hydrogenation) and isobutylene (by hydration to yield MTBE) Raffinate III, in tum, is what remains after the removal of I-butene from raffinate II The Huels process is run below 100 C under sufficient pressure to ensure liquid-phase operation Until the mid-I970s metal-catalyzed propylene dimerization had practical significance in isoprene manufacture Goodyear developed a process to dimerize propylene in the presence of tri-n-propylaluminum to yield 2-methyl-I-pentene 16 ,95,96 This was then isomerized to 2-methyl-2-pentene followed by cracking into isoprene and methane This and other synthetic pocesses, however, are no longer practiced since they are not competitive with isoprene manufactured by cracking of naphtha or gas oil Codimerization of ethylene and I,3-butadiene is also of commercial significance since the product I,4-hexadiene is used as a comonomer in the manufacture of ethylene-propylene-diene elastomers.

Rhodium and nickel catalysts are used since they are the most active and selective, bringing about the formation of the required trans isomer97 Oligomerization of ethylene to cx-olefins is undeniably the most important oligomerization reaction 17 ,98-101 C IO-C 18 cx-olefins thus produced are used mainly as intermediates to manufacture detergents Three technologies have been commercialized Two processes (Ethyl and Chevron/Gulf) use triethylaluminum to effect Ziegler chain growth chemistry 102 In the conventional ethyl process a stoichiometric chain growth reaction leads to the formation of an aluminum alkyl mixture The chain length of the alkyl groups corresponds to a statistical distribution with a maximum around C6-C IO alkenes The product is usually recycled to get a better yield of the most desirable C6-C 14 alkenes The ethyl technology is a two-step process since the aluminum alkyl mixture is subsequently reacted in a displacement reaction.

During this treatment added excess ethylene displaces the alkyl groups to form terminal alkenes and triethylaluminum The first step is carried out at relatively low temperature (90-120 C, 100-200 atm) where chain growth predominates, whereas displacement requires more severe reaction conditions (260-31O C, 7-20 atm) Instead of the displacement reaction, aluminum alkyls may be oxidized with dry air to produce aluminum alkoxides that, after hydrolysis with dilute sulfuric acid or water, yield linear primary alcohols with an even number of carbon atoms (fatty.

Using type with brushstrokes and transparency can also result in some eye-catching effects. To create embossed type, follow these steps:

The following sections cover each of these areas separately, while also providing a specific mobility application representative of each.

If you use an OPI-based proxy workflow that is, if an OPI-based service provider supplies you with low-resolution versions of graphics files that will eventually be replaced by high-resolution files during output select the Read Embedded OPI Image Links option if you want InDesign, rather than your service provider, to perform image replacement during output.
