TL;DR: Ethanol and isopropyl alcohol greatly increase systemic exposure of extrahepatic organs to N-nitrosodimethylamine in a primate.
Abstract: Low concentrations of N -nitrosodimethylamine are metabolized in rodent and human liver by cytochrome P450IIE1, an activity competitively inhibitable by ethanol. In rodents coadministration of ethanol with N -nitrosodimethylamine results in increased tumorigenicity in extrahepatic organs, probably as a result of reduced hepatic clearance. To test this concept in a primate, the effects of ethanol cotreatment on the pharmacokinetics of N -nitrosodimethylamine were measured in male patas monkeys. Ethanol, 1.2 g/kg given p.o. before i.v. N -nitrosodimethylamine (1 mg/kg) or concurrently with an intragastric dose resulted in a 10–50-fold increase in the area under the blood concentration versus time curves and a 4–13-fold increase in mean residence times for N -nitrosodimethylamine. Isopropyl alcohol, 3.2 g/kg 24 h before N -nitrosodimethylamine, also increased these parameters 7–10-fold; this effect was associated with persistence of isopropyl alcohol and its metabolic product acetone, both IIE1 inhibitors, in the blood. While no N -nitrosodimethylamine was detected in expired air, trace amounts were found in urine. Ethanol and isopropyl alcohol pretreatment increased the maximum urinary N -nitrosodimethylamine concentration 15–50-fold and the percentage of the dose excreted in the urine by 100–800-fold. Thus ethanol and isopropyl alcohol greatly increase systemic exposure of extrahepatic organs to N -nitrosodimethylamine in a primate.

TL;DR: In this paper, a multi-directional flow of isopropyl alcohol vapor is used to uniformly dry a semiconductor substrate, and the top and bottom portions of the substrate are dried at approximately the same time.
Abstract: A multi-directional flow of isopropyl alcohol vapor is used to uniformly dry a semiconductor substrate. In one embodiment of the invention, isopropyl alcohol vapor (19), which is generated by an external vapor source (30), is injected into the vapor drying system at a location near the top portion (28) of the semiconductor substrate (20), while internally generated isopropyl alcohol vapors (18) are directed toward the bottom portion (26) of the semiconductor substrate (20). Therefore, both the top (28) and the bottom (26) portions of the semiconductor substrate (20) are dried at approximately the same time.

TL;DR: It is concluded that there is a positive relationship between acetone production and isopropyl metabolism in the setting of a toxic ingestion of isopopyl alcohol.
Abstract: A toxic dose of isopropyl alcohol was ingested by six male mongrel dogs to evaluate the relationship between acetone production and isopropyl degradation. Maximal serum isopropyl levels were achieved approximately 2 to 3 hours after ingestion of 60 mL of 70% isopropyl alcohol. Acetonemia occurred rapidly in the serum (within 15 minutes of ingestion) and continued to rise after isopropanol levels plateaued. The levels of acetone and isopropanol correlated positively throughout the study model with an r of .54 (P less than .001). It is concluded that there is a positive relationship between acetone production and isopropyl metabolism in the setting of a toxic ingestion of isopropanol. Acetone's persistence as a serum marker may be beneficial in identifying isopropyl hours after a suspected ingestion.

TL;DR: In this paper, Molybdenum oxide catalysts doped or mixed with (1−50) mol% Fe3+ ions were prepared and the structure of the original samples and calcined at 400 °C were characterized using DTA, X-ray diffraction and IR spectra.
Abstract: Molybdenum oxide catalysts doped or mixed with (1–50) mol% Fe3+ ions were prepared. The structure of the original samples and calcined at 400 °C were characterized using DTA, X-ray diffraction, and IR spectra. The measurements of the electrical conductivity of calcined samples with and without isopropyl alcohol revealed that the conductance increases on increasing the content of Fe3+ ions up to 50 mol%. The activation energies of charge carriers were determined in presence and absence of alcohol. The catalytic dehydration of isopropyl alcohol was carried out at 250 °C using flow system. The results obtained showed that the doped or mixed catalysts are active and selective towards propene formation. However, the catalyst containing 40 mol% Fe3+ ions exhibited the highest activity and selectivity. Correlations were attempted between the catalyst composition and their electronic and catalytic properties. Probable mechanism for the dehydration process is proposed in terms of surface active sites.

TL;DR: The electron transfer ability of the 50% isopropyl alcohol/NaHSO3 system increases with increasing temperature but is less than that of aqueous anthrahydroquinone at similar temperatures as mentioned in this paper.
Abstract: Compound 1, which incorporates a hex-5-enyl group on a quinone methide precursor, has been used to demonstrate that NaHSO3 in 50% isopropyl alcohol exhibits electron transfer reactions. There is a signifi- cant solvent effect associated with this system since NaHSO3 in aq. NaOH showed very few products typical of an electron transfer system, while 50% isopropyl alcohol by itself at 150°C provided some of the typical products. The electron transfer ability of the 50% isopropyl alcohol/NaHSO3 system increases with increasing temperature but is less than that of aqueous anthrahydroquinone at similar temperatures.

Journal ArticleDOI
TL;DR: In this paper, an enzyme-linked immunosorbent assays method and a high-performance liquid chromatography method with fluorescence detector were used to determine the toxins in the feed and eluates from the adsorption columns.
Abstract: Physical removal of aflatoxins from cottonseed by solvent extraction with ethanol or isopropyl alcohol is technically feasible. These solvents used in the removal process are recycled to extraction systems after regeneration by distillation. However, distillation is costly due to high latent heat of the solvents. Adsorption techniques have been explored as a method to remove aflatoxins from these solvents. Enzyme-linked immunosorbent assays method and a high-performance liquid chromatography method with fluorescence detector were used to determine the toxins in the feed and eluates from the adsorption columns. Experimental data indicate that montmorillonite is highly effective for adsorptive aflatoxin removal. Adsorption data with neutral alumina and silica are also presented. Ethanol and ethanol-based miscellas, obtained from alcoholic cottonseed extractions were spiked with aflatoxins for this investigation.
