DeBenneville, Peter L. published the artcileBehavior of aliphatic aldehydes in the Leuckart-Wallach reaction, Application of 2-Ethyl-N,N-dimethylhexan-1-amine, the publication is Journal of the American Chemical Society (1950), 3073-5, database is CAplus.

The Leuckart-Wallach reaction with aliphatic aldehydes and secondary amines is initiated at a generally lower temperature than in the case of ketones and aromatic aldehydes and generally gives good yields of products. A possible explanation is the involvement of the H on the ¦Á-C atom of the aldehyde through an enamine intermediate. The following compounds were used: Aldehydes, EtCHO (I), PrCHO (II), iso-PrCHO (III), C₆H₁₃CHO (IV), BuEtCHCHO (V), Me₃CCH₂CHMeCH₂CHO (VI); ketones, cyclohexanone (VII), PhAc (VIII); amines, morpholine (IX), piperidine (X), Me₂NH (XI), (iso-Pr)₂NH (XII), (HOC₂H₄)₂NH (XIII), MeNHC₉H₁₉ (XIV), and PhNHMe (XV). The enamines were prepared by the method of Mannich and Davidsen (C.A. 30, 8217.2), with anhydrous K₂CO₃ or CaO as catalyst and temperatures of 5-50¡ã; the intermediate diimine was converted to the enamine by distillation One mol. of the enamine is treated dropwise with 1-1.1 mols. 98% HCO₂H, heated 1-2 h. at 50-70¡ã (occasionally at 90¡ã), poured into dilute HCl, extracted with ether, made basic with NaOH, and again extracted with ether.

Ten strains of endophytes were purified from the endophytes in fresh Lily. One of them was selected as a sample because of its fragrant metabolite and speedy growth. The metabolite was analyzed by GC-MS. The results showed that the main aroma components were alkenes, alcs., esters and alkyls, for example, 4-penten-2-ol (67.29%), 1,3-diazine (3.42%), 1,2-benzenedicarboxylic acid, bis(2-methylpropyl)ester (2.04%), 9,12-octadecadienoicacid (Z,Z) (1.72%), 1-butanol, 2-Me (1.38%), phenylethyl, alc.

Hu, Xianbo published the artcileEffect of a silicate filler on the crystal morphology of poly(trimethylene terephthalate)/clay nanocomposites, HPLC of Formula: 28056-87-3, the publication is Journal of Polymer Science, Part B: Polymer Physics (2003), 41(19), 2275-2289, database is CAplus.

A series of intercalated poly(trimethylene terephthalate) (PTT)/clay nanocomposites were prepared in a twin-screw extruder by the melt mixing of PTT with either quaternary or ternary ammonium salt-modified clays. The morphol. and structure, along with the crystallization and melting behavior, and the dynamic mech. behavior of the composites were characterized by X-ray diffraction, transmission electron microscopy, differential scanning calorimetry, and dynamic mech. thermal anal. The results showed that the PTT chains could undergo center-mass transport from the polymer melt into the silicate galleries successfully during the blending and extrusion process. More coherent stacking of the silicate layers was reserved at higher clay concentrations and shorter blend times. Compared with conventionally compounded composites, the nanoscale-dispersed organophilic clays were more effective as crystal nucleation agents. The influence of the nano-silicates on the crystallization and melting behavior of PTT became distinct when the concentration of clay was around 3 wt%. The changes in the crystallization behavior of the polymer/clay nanocomposites depended not only on the size of the silicates but also on the intrinsic crystallization characteristics of the polymers. The resulting nanocomposites showed an increase in the dynamic modulus of PTT and a decrease in the relaxation intensity (both in loss modulus and loss tangent magnitude).

A fused iron catalyst consisting of Fe₃O₄ (natural or synthetic magnetite):V₂O₅:CuO in 100:5:1.5 mass ratio was highly selective for the gas-phase hydroamination of internal alcs. and alkyl ketones: a selectivity of 74% was observed for the hydroamination of 2-octanone to N,N-dimethyl-N-(2-octyl)amine (I). Catalyst optimization studies are reported for a variety of promoters: the highest (83%) yield of I from 2-octanone was obtained with a catalyst composition of 100 natural Fe₃O₄:10 Al₂O₃:1 CuO. Pressure and temperature are also optimized.

Kim, Jang-Yup published the artcileReal time XRD analysis of polystyrene/clay nanocomposites by in-situ polymerization, Name: 2-Ethyl-N,N-dimethylhexan-1-amine, the publication is Polymer (Korea) (2005), 29(1), 87-90, database is CAplus.

We have examined the exfoliation behavior of layered clay during in-situ polymerization with styrene by using real time XRD anal. The 4C1 beam line at the Pohang Accelerator Laboratory (PAL) was used for this study. Different exfoliation behaviors have been shown to depend on the cation exchange capacity (CEC) of clay and the chem. structure of organic modifiers. For 10A-MMT and ISA-MMT having high CEC, no peak shifts were observed on real time XRD anal. during polymerization 2¦È For 25A-MMT and VDAC-MIMT, each having low CEC’s as well as aromatic benzene moieties and vinyl groups, resp., decreased as polymerization time increased.
