Gibka, Julia published the artcileDerivatives of tridecan-X-ones (X = 2-7): Synthesis and spectral data, Synthetic Route of 58783-82-7, the main research area is tridecanone diol acetalization; acetal tridecanone preparation; dioxolane preparation; dioxane preparation; tridecyl acetate preparation.

Tridecan-x-ones (x = 2-7) have been used as starting materials in the synthesis of ethylene and propylene acetals, tridecan-x-ols and their acetates. Cyclic acetals were obtained in the reaction between ketone and ethane-1,2-diol or propane-1,2-diol in toluene in the presence of sulfosalicylic acid as a catalyst. Alcs. were synthesized in the reduction of ketones with sodium borohydride in water/2-propanol. Acetates were prepared by the esterification of alcs. with acetic anhydride in the presence of sodium acetate. All derivatives were prepared in a 2-5 g scale. Phys. properties (b.p., refractive index, elemental anal.) and spectral data (IR, 1H NMR) for all the synthesized derivatives of tridecan-x-ones have been determined

Kachholz, T. published the artcileDegradation of long chain alkanes by bacilli. II. Metabolic pathways, Synthetic Route of 58783-82-7, the main research area is Bacillus alkane metabolism temperature.

Five species of bacilli tested at 30° degraded hydrocarbons by cooxidn. A subterminal degradation pathway in these bacilli was proved by the presence of isomeric esters (like the products of Baeyer-Villiger oxidation of ketones), diols, ketols, and diketones. The composition of fatty acids in the lipids of bacilli grown with and without alkane and with position of fatty acids in the lipids of bacilli grown with and without alkane and with labeled n-tridecane suggested a subterminal, partly di-subterminal, pathway. Bacillus stearothermophilus did not grow on alkane as the sole C source even in a thermophilic temperature range; oxidation products were formed in amounts 20-fold less when grown on cooxidn. medium at 50°, compared to product formation on the same medium at 30°.

No Bacillus among 14 type strains and 100 soil isolates could assimilate C14-C18 alkanes as sole C source, although 5 type strains could oxidize alkanes in the presence of glucose. When grown with pure n-C13H28, or n-C14H30, the 5 strains gave mainly mixtures of the corresponding secondary alcs., with some ketone and small amounts of primary alcs. B. lentus oxidized C13H28 poorly compared to C14H30. B. stearothermophilus and B. macerans gave �0-fold more alcs. than the other species. The extracellular fatty acid composition of B. macerans changed when alkane was added to a glucose-based medium.

Von Wettstein-Knowles, Penny published the artcile7-Oxopentadecan-2-ol esters – a new epicuticular wax lipid class, Recommanded Product: 5-Tridecanol, the main research area is oxopentadecanol ester barley epicuticular wax.

The alkan-1-ol and alkan-2-ol esters (primarily, C38-48 and C33-35, resp.) of barley epicuticular waxes are known to arise via 2 different biosynthetic pathways. A third type of ester (∼0.2% by weight of spike wax), previously unknown in these plant lipids, was identified. The esters were isolated via preparative TLC together with the longer chain primary alcs. From the effects of chem. treatments analyzed with the aid of TLC and gas chromatog. (GC), the presence of an oxo group in the alc. moiety was deduced. GC-mass spectrometry of the esters and their alc. moieties before and after NaBH4 treatment and of the fatty acid moieties resulted in the identification of at least 3 7-oxopentadecan-2-ol esters (C33, C35, and C37). 2,7-Dihydroxypentadecane was synthesized and its mass spectrum found to be identical to that of the reduced ester alc. moiety. A determination of the relative amounts of these esters in 10 different genotypes supports the contention that biosynthetically the pentadecan-2-ol esters are precursors of those containing an oxo group on C 7.

Ramirez-Contreras, Rodrigo published the artcileChemo- and Regioselective Functionalization of Polyols through Catalytic C(sp3)-C(sp3) Kumada-Type Coupling of Cyclic Sulfate Esters, Synthetic Route of 58783-82-7, the main research area is chemoselective regioselective functionalization Kumada type coupling cyclic sulfate ester; copper catalyst coupling cyclic sulfate ester alkyl Grignard reagent.

This contribution describes a copper-catalyzed, C(sp3)-C(sp3) cross-coupling reaction of cyclic sulfate esters, a distinct class of electrophilic derivatives of polyols, with alkyl Grignard reagents to afford functionalized alc. products in good yields. The method is operationally simple and highlights the potential of cyclic sulfate esters as highly reactive substrates in catalytic, chemoselective polyol transformations.

Tanimoto, Toshiko published the artcileRetention behavior of positional isomers of disubstituted cyclomalto-oligosaccharide (cyclodextrin) derivatives on an ODS column, Formula: C13H28O, the main research area is disubstituted cyclomalto oligosaccharide retention liquid chromatog; HPLC disubstituted cyclomalto oligosaccharide ODS column; cyclodextrin derivative positional isomer ODS column liquid chromatog.

The correlation between hydrophobic effects and structures of three and four positional isomers of 61,6n-di-O-triphenylmethyl (trityl)- or 61,6n-di-O-tert.- butyldimethylsilyl (tert.-BuMe2Si)-cyclomaltohexaoses (cG6s, α-cyclodextrin) (n = 2-4), -cyclomaltoheptaoses (cG7s, β-cyclodextrin) (n = 2-4), and -cyclomaltooctaoses (cG8s, γ-cyclodextrin) (n = 2-5) on an ODS column are discussed. Cyclodextrins with two hydrophobic-substituted groups bonded to hydroxyl groups tended to show low retention of positional isomers in which the binding positions of the two substituted groups on the cyclodextrin ring were far apart from each other.

Yang, Jing published the artcileHigh-quality bio-oil from one-pot catalytic hydrocracking of kraft lignin over supported noble metal catalysts in isopropanol system, SDS of cas: 58783-82-7, the main research area is kraft lignin isopropanol metal catalyst bio oil catalytic hydrocracking; Hydrocracking; Isopropanol; Kraft lignin; Nobel metal catalysts; Orthogonal array design.

Catalytic hydrocracking of kraft lignin was carried out in isopropanol system and an orthogonal array design (OAD) was employed to optimize the exptl. conditions. GC-MS/FID, elemental anal., GPC and 1H-13C HSQC NMR were carried out for entire investigation of the liquid products. The results indicated that the hydrocracking process was thermally controlled and catalysts showed significant influences on the product distributions. Comparing with Pd/C, Pt/C and Ru/C, Rh/C inhibited the self-condensation of isopropanol and reduced the formation of oxygenic-chain compounds The excellent catalytic activity for phenols conversion was obtained over Rh/C. The routes of oxygenic-chain compounds formation and phenol conversion were proposed in detail. The least oxygenic-chain compounds formation, the highest phenols conversion (93.4%), the lowest O/C ratio (0.094) and the highest HHV (37.969 MJ/kg) provided the possibility of the high quality bio-oil obtained over Rh/C in isopropanol medium.

Gibka, J. published the artcileOdor characteristics of aliphatic metameric C-13 ketones, alcohols and their derivatives, Recommanded Product: 5-Tridecanol, the main research area is odor structure tridecanone alc acetal.

The odor of a series of tridecanones their derivatives was determined The relations between structure and odor in the whole family of the tridecanone derivatives were described. Pleasant notes accompanied fatty-type ketone odors, e.g., floral for tridecan-3-one, and fruity for tridecan-6-one. Alcs., however, were less interesting, all having only a faint or mild waxy odor. Acetates had stronger odors than the corresponding alcs. Acetals were the most interesting group of compounds They all had nutritive odors with different notes: fruity, spicy, herbaceous or floral, and low odor threshold (10-20 ppm). The derivatives of tridecan-6-one have odors with spicy and vegetable notes.
