The infrared and visible spectrophotometric data of uranyl soaps showed that metal-oxygen bonds in uranyl soaps are not purely ionic but are partially covalent in character.The X-ray diffraction patterns confirmed the double-layer structure with molecular
Direct conversion of carboxylic acids (Cn) to alkenes (C2n - 1) over titanium oxide in absence of noble metals

Carbon-carbon bond formations and deoxygenation reactions are important for biomass up-grading. The classical ketonic decarboxylation of carboxylic acids provides symmetrical ketones with 2n + 1 carbon atoms and eliminates three oxygen atoms. Herein, this reaction is carried out with titanium oxide at 400°C, and an olefin with 2n + 1 carbon atoms is obtained instead of the ketone. For olefin formation hydrogen transfer reactions are required from suitable precursors to form aromatics and coke. Additional aldol condensation reactions increase further molecular weight in the product mixture. Hence, a combination of titanium oxide with a hydrodeoxygenation bed provides double amount of diesel fuel as the combination with zirconium oxide when reacting hexose-derived pentanoic acid.

It is an object of the present invention to provide a trehalose compound having high immunopotentiating activity and low toxicity. The trehalose compound is represented by formula (1). (In the formula, X and X' each represents a phenyl, a naphtyl, R1-CHR1- (wherein R1 and R2 each represents a C7-C21 alkyl group or the like) or the like; and n and n' each independently represents an integer of 0-3). The compound exhibits a high activating effect on macrophages and neutrophils.
