Industrial solvents Solvents and a wide range of volatile compounds are present in commercial products such as gasoline, paint thinners, aerosol propellants, glues, rubber cements, and shoe polish. Because of their ready availability, these substances are most frequently abused by children in early adolescence. Active ingredients that have been identified include benzene, hexane, methylethylketone, toluene, and trichloroethylene. Many of these are toxic to the Uver, kidneys, lungs, bone marrow, and peripheral nerves and cause brain damage in animals. 

Male preteen children are most likely to experiment with solvent inhalation. Abuse of nitrous oxide is relatively common. Toxic inhalants such as heptane, hexane, methylethylketone, toluene, and trichloroethylene may result in central and peripheral neurotoxicity, liver and kidney damage, and pulmonary disease. Sudden death has occurred following inhalation of fluorocarbons. Industrial solvents rarely cause methemoglobinemia, but this (and headaches) may occur following excessive use of nitrites. The answer is (C). 

Basically, the following solvents are used petroleum naptha 60/95, petroleum naptha 80/110, ethylacetate, acetone (dimethylketone), butanone (methylethylketone), toluene (methylbenzene), ethanol, isopropanol, or sometimes tetrahydrofiirane, which is a suitable solvent for PVC. For adhesive storage, key data of the corresponding solvents such as boiling point, flash point, and the rate of evaporation are necessary. O Table 36.1 shows a summary of these data for the solvents mentioned above. (Flash point refers to the lowest temperature at which a volatile liquid can vaporize to form an ignitable mixture in air.)... 

Plummer invented a process for the biodesulfurization of hydrocarbons [157], in which organic sulfur compounds contained in liquid hydrocarbons are converted to elemental sulfur. The reaction is carried out in the presence of a biocatalyst and hydrogen, by dissolving completely the liquid hydrocarbons in an organic solvent, such as a nucleophilic and/or electrophilic solvent(s). The nucleophilic solvent should have a pKa greater than 2, and the electrophilic solvent more negative than -2. Recommended nucleophilic solvents include -butylamine, diethylamine, butanediamine, ethylenimine, toluene, pyridine, aniline, and acetophenone. The electrophilic solvents could be methylethylketone, pyrrole, or benzaldehyde. 

P.Y.182, which has been available for some years, provides somewhat reddish shades of yellow and is tinctorially strong. It is sensitive to a variety of organic solvents, especially to ketones such as methylethylketone and cyclohexanone, as well as to aromatic solvents such as toluene or xylene. In this respect, the pigment equals step 2 on the 5-step scale (Sec. 1.6.2.1). P.Y.182 is targeted for the paint and the plastics industry.

Jain (20), in his introduction, notes that the direct injection of the blood sample does not give "ghost" or interfering peaks. The column can be used for a long time. The method is not limited to ethanol, since methanol, isopropanol, and acetone as well as toluene, methylethylketone, and xylene (associated with glue sniffing) can be quickly determined. 

Figure 13.29. Composition profiles and flowsketches of two azeotropic distillation processes (adapted by King, 1980). (a) Separation of ethanol and water with benzene as entrainer. Data of the composition profiles in the first column were calculated by Robinson and Gilliland, (1950) the flowsketch is after Zdonik and Woodfield (in Chemical Engineers Handbook, McGraw-Hill, New York, 1950, p. 652). (b) Separation of n-heptane and toluene with methylethylketone entrainer which is introduced in this case at two points in the column (data calculated by Smith, 1963).

Some hydrocarbon separations can be effected azeotropically. Figure 13.28(b) shows an operation with methylethylketone which entrains n-heptane away from toluene. Hexane in turn is an effective entrainer for the purification of methylethylketone by distilling the latter away from certain oxide impurities that arise during the synthesis process. 

Suspensions of HTSC for the electrophoretic deposition of bismuth [403-409] and thallium [403] HTSC, various cuprates of rare-earth metals and barium [204, 407,410-414], and also silver HTSC [415,416] and PbO-HTSC [417] compositions have been used. These are prepared in acetone, acetonitrile, toluene, butanol, methylethylketone, or mixed solvents. They contain chemically pure materials (silver is introduced as AgaO) dispersed thoroughly, first mechanically and then in liquid) by ultrasonic treatment (in which case the particles became charged). The choice of solvent is by and large determined by its effect on the stability of the deposited oxide [417].

Moreover, Ohta and Oono (1982), using experimental data of light scattering from polystyrene solutions of different fractions (3-10 < M < 2.6 10 ) in toluene and methylethylketone (Wiltzius et al., 1983), have plotted a universal dependence of...
