1.2- Epoxy ethane

In contrast, a number of alkene epoxides (10.3) are chemically quite stable, i.e., intrinsically less reactive than arene oxides. Examples of epoxide metabolites that have proven to be stable enough to be isolated in the absence of degrading enzymes include 1,2-epoxyoctane (10.4), 1,2-epoxycyclohex-ane (10.5), 1-phenyl-1,2-epoxy ethane (styrene oxide, 10.6), and cis- 1,2-diphenyl-1,2-epoxyethane (cfv-stilbene oxide, 10.7) [12], The same is true of alclofenac epoxide (10.8), hexobarbital epoxide (10.9), and a few other epoxides of bioactive compounds. [Pg.611]

With sodium ethyl xanthate as collector, the frothing capabilities of various synthesized dodecyl phenyl polypropylene ether alcohol frothers from dode-cylphenol and epoxy ethane in the flotation of lead zinc ore of Australia Broken Hill are listed in Table 3.2. As shown in Table 3.2, the frothing capability of dodecyl phenyl polypropylene ether alcohol is as same as that of eucalyptus oil. [Pg.121]

While all three ring systems are opened by cationic or acid-initiated mechanisms, only the 1,2-epoxide oxirane can be polymerized by both anionic and cationic initiation. Notice that only 1,2-epoxy ethane, ethylene oxide, is derived by epoxidation of an alkene and, thus, is the only alkylene oxide in this series. [Pg.36]

Tetrakis (4-hydroxyphenyl)ethane is prepared by reaction of glyoxal with phenol in the presence of HCl. The tetraglycidyl ether [27043-37-4] (4), mp ca 80°C, possesses a theoretical epoxide functionaUty of four with an epoxy equivalent weight of 185—208 (4). [Pg.364]

Until the 1970s the chemical used as the impregnating and dielectric medium for capacitor units was PCB (polychlorinated biphenyl) liquid. It was found to be toxic and unsafe for humans as well as contamination of the environment. For this reason, it is no longer used. The latest trend is to use a non-PCB, non-toxic, phenyl xylyl ethane (PXE-oil), which is a synthetic dielectric liquid of extremely low loss for insulation and impregnation of the capacitor elements or to use mixed polypropylene or allpolypropylene (PP) liquids as the dielectric. A non-oil dielectric, such as epoxy resin, is also used. [Pg.811]

Epoxides can also be rearranged to aldehydes or ketones on treatment with certain metallic catalysts.A good way to prepare p-diketones consists of heating a,P-epoxy ketones at 80-140°C in toluene with small amounts of (Ph3P)4Pd and 1,2-bis(diphenylphosphino)ethane. ... [Pg.1398]

P-Diketonesfrom %/i-epoxy ketones. 2 In the presence of this Pd(0) complex a,/ -epoxy ketones isomerize to /3-dikelones. An added ligand is usually necessary to avoid precipitation of palladium. The most satisfactory adjunct is l,2-bis(diphenyl-phosphino)ethane (dpe). The reaction is conducted in toluene at 80-140° for 10 100 hours. The isomerization is facile with strained epoxides it is sluggish with epoxides bearing an a-alkyl group. [Pg.389]

Tetrabromobisphenol A is used in epoxy resins especially for glass fiber reinforced used in printed circuit board. Nonreactive compounds such as tetrabromophatalate ester, bis(tribromophenoxy) ethane, and decabromodiphenyl ether are also used. The use of synergists, such as antimony oxide, reduces the quantity of brominated flame retardant necessary but decreases the electrical properties required. [Pg.90]
