Toxic alcohols that clinicians commonly encounter are ethylene glycol, methanol, and isopropanol. Adults ingest these either for suicidal intent or to achieve inebriation, since these substances are readily available and cheaper than alcohol. Nevertheless, assorted alcohols are used very often in many applications and any alcohol can be toxic if ingested in large enough quantities. Toxic alcoho...

Electroantennograms (EAGs) were recorded from unmated, laboratory-reared, male and female oriental fruit flies, Dacus dorsalis, in response to a range of between C~ and Cl2 carbon chain-length saturated and unaturated aliphatic alcohols and aldehydes, most all of which are known host-plant volatiles. Only two of the 35 compounds tested elicited significantly larger EAGs from female than male an...

We investigated the acute toxic and metabolic effects of 23-aliphatic alcohols (16 saturated and 7 unsaturated) in the isolated perfused rat liver at a concentration of 65.1 mmol/l (approximately 0.3% ethanol). The capacity of the straight chain primary alcohols (methanol, ethanol, 1-propanol, 1-butanol and 1-pentanol) to release the enzymes glutamate-pyruvate transaminase (GPT), lactate dehydr...

Lipase from papaya (Carica papaya) latex (CPL), Candida antarctica lipase B (Novozym 435, NOV) and Rhizomucor miehei lipase (Lipozyme IM 20, LIP) were used as biocatalysts for the esterification of caprylic acid with straight-chain saturated C(4)-C(18) alcohols and unsaturated C(18) alcohols, such as cis-9-octadecenyl (oleyl, C(18:1), n-9), cis-6-octadecenyl (petroselinyl, C(18:1), n-12), cis-9...

The isolation and properties of a group of alcohols from the mycelium of Aspergillus fumigatus Fresenius are described. Mass-, nuclear-magnetic-resonance- and infrared-spectrometric studies coupled with evidence from ozonolytic degradation and chromatography show the mixture to contain hexahydroprenols-18, -19, -20, -21, -22, -23 and -24. Each contains a saturated ;hydroxy-terminal' isoprene re...

Cetane numbers (C#) for the homologous series of straight-chain, saturated n-alcohols, CS-C12 and C14, were determined according to ASTM D 613. Measured C# ranged from 18.2-80.8 and increased linearly with carbon number (CN). Regression analyses developed equations that related various physical properties or molecular characteristics of these alcohols to calculated CU. The degree of relationshi...

Steroidal allylic alcohols formed Na+ adduct ion peaks [M+Na]+ by the addition of NaCl in FAB mass spectrometry. A comparison of the intensities of the adduct ion peaks of allylic alcohols with those of the corresponding saturated alcohols and olefin suggested that the olefinic double bond and the proximal hydroxyl group had coordinated to Na+. The adduct ion was stable and did not undergo dehy...

Base-free catalytic alpha-alkylation of active methylene compounds with primary alcohols was successfully achieved using an [IrCl(cod)](2) complex in the presence of PPh(3) to afford the corresponding saturated alpha-alkylated products in good yields.

Fourteen yeast strains from six genera were analysed for the presence of long-chain alcohols. Six strains from three genera contained long-chain alcohols, highest levels being found in Candida afbicans. The alcohols were identified and determined by TLC, GLC and GLC-MS. The major long-chain alcohols synthesized by these organisms were saturated, primary alcohols with C1 4, C I 6 or C18 chain le...
