Naphthalene methyl

Another method which might avoid the problems associated with natural pitch feeds involves producing mesophase from a synthetic precursor. Recently, Mochida et al. [30] developed a process in which mesophase is produced by the polymerization of naphthalene or methyl naphthalene, with the aid of a HF/BF3... [Pg.127]

Laser flash photolysis techniques offer the possibility of examining in detail the transient processes responsible for the photostabilizing effect discussed above. The triplet lifetimes are frequently too short, even for this technique however, they can still be estimated using as a probe the quenching by 1-methyl-naphthalene, which leads to the formation of its easily detectable triplet. The optical absorbance due to the 1-methylnaphthalene triplet (Aft) produced as a result of energy transfer is related to the Stern-Volmer slope by equation 5, where N stands for... [Pg.22]

These conclusions were not applicable when sediment was the source of hydrocarbons. McCain et al. (5) studied the bioavailability of petroleum in sediment to English sole (Parophrys vetu-lus). Sediments rich in alkylated and non-alkylated benzenes and naphthalenes, together with fluorene and phenanthrene, were employed. After 11 days of exposure, samples of skin, muscle, and liver were examined. Fluorene and phenanthrene were not accumulated in the test fish however, significant concentrations of 1-methyl naphthalene, 2-methyl naphthalene, 2,6-dimethyl naphthalene and 1,2,3,4-tetramethylbenzene, were found in skin and liver (Table II) 1-methyl naphthalene and 2-methyl naphthalene were the major components of muscle. In each tissue examined, 1-methyl-naphthalene was the major component 1,2,3,4-tetramethylbenzene occurred in relatively low concentrations in skin and muscle in comparison to naphthalenes containing one and two alkyl groups. [Pg.59]

Mel ancon and Lech (9) demonstrated that rainbow trout exposed to both radiolabeled naphthalene and 2-methyl naphthalene contained significant portions of polar compounds (unspecified) after about four weeks of exposure (Table IV). Mai ins et al. (15J showed that a variety of metabolic products accumulate in tissues and... [Pg.65]

The alkyl-substituent pattern for some PAHs series (e.g., alkylnaphthalenes, phenanthrene/anthracene, pyrene/fluoranthene, m/z 228 and m/z 252) are shown in Figs. 6-9, respectively. The parent PAHs and their alkylated homologs are determined in GC-MS data by monitoring their corresponding molecular weights. For example, for the naphthalene series the ions at m/z 128,142 methyl-naphthalenes, 156 C2-naphthalenes, 170 C3-naphthalenes, and 184 C4-naphtha-lenes are monitored (Fig. 6). The GC elution orders of the C2-naphthalene and C3-naphthalene isomers have been reported [144,145]. [Pg.16]
