Decarboxylation of Fatty Acids with Triruthenium Dodecacarbonyl: Influence of the Compound Structure and Analysis of the Product Mixtures.

Recently, the decarboxylation of oleic acid (9()-octadecenoic acid) catalyzed by triruthenium dodecacarbonyl, Ru(CO), to give a mixture of heptadecenes with concomitant formation of other hydrocarbons, heptadecane and C17 alkylbenzenes, was reported. The product mixture, consisting of about 77% heptadecene isomers, 18% heptadecane, and slightly >4% C17 alkylbenzenes, possesses acceptable diesel fuel properties. This reaction is now applied to other fatty acids of varying chain length and degree of saturation as well as double-bond configuration and position.

A comparison of used cooking oils: a very heterogeneous feedstock for biodiesel.

Used cooking or frying oils are of increasing interest as inexpensive feedstock for biodiesel production. In this work, used frying oils obtained from 16 local restaurants were investigated regarding their fatty acid profile vs. the fatty acid profile of the oil or fat prior to use.

Preparation of spread oils meeting U.S. Food and Drug Administration Labeling requirements for trans fatty acids via pressure-controlled hydrogenation.

On July 11, 2003, the U.S. Food and Drug Administration (FDA) announced final regulations for trans fatty acid (TFA) labeling.

Triacylglycerol structure and composition of hydrogenated soybean oil margarine and shortening basestocks.

The composition and structures of triacylglycerols (TAG) in a commercially prepared hydrogenated soybean oil margarine basestock [iodine value (IV) 65, 39.7% trans fatty acids] were determined by high-performance liquid chromatography (HPLC) in tandem with atmospheric pressure chemical ionization (APCI) mass spectrometry (MS). The basestock was separated by preparative HPLC into four fractions.

Carbamazepine-induced release of serotonin from rat hippocampus in vitro.

Purpose: Carbamazepine is one of several antiepileptic drugs (AEDs) that release the inhibitory neurotransmitter serotonin as part of their pharmacodynamic action on brain neurons. We undertook this study to investigate the cellular processes by which carbamazepine (CBZ) releases serotonin from brain tissue.

Methods: Tissue slices were prepared from hippocampi of Sprague-Dawley rats.
