Matusik, Jakub published the artcileCharacterization of kaolinite intercalation compounds with benzylalkylammonium chlorides using XRD, TGA/DTA and CHNS elemental analysis, Quality Control of 23616-79-7, the publication is Applied Clay Science (2013), 433-440, database is CAplus.

Kaolinite of high structural order was intercalated with selected ammonium salts containing a benzyl group: benzyltrimethylammonium (B1), benzyltributylammonium (B2), benzalkonium (B3), benzyldimethyltetradecylammonium (B4) and benzyldimethylhexadecylammonium (B5) chlorides. As a precursor, a methoxy-kaolinite was used which had OCH₃ methoxyl groups attached to the octahedral sheet. Such change of the octahedral surface character enabled intercalation of the salts which was not possible using other precursors (e.g. kaolinite-DMSO). The new intercalation compounds were characterized using XRD, thermal anal. (TGA/DTA) and CHNS elemental anal. The XRD revealed a significant shift of the kaolinite basal reflection to higher values range from ~14 Å (B1 salt) to ~38 Å (B5 salt) which confirmed the intercalation. The d values depended on the type of used salt as well as on its initial concentration The estimated space occupied by each mol. enabled to calculate the maximal molar capacity of the kaolinite in relation to the salts. The results were compared with the chem. formulas of the materials calculated from CHNS measurements. The TGA/DTA analyses were helpful to confirm the successful intercalation of the selected salts as the thermal decomposition of the kaolinite derivatives took place at higher temperatures as compared to appropriate phys. mixtures

Matusik, Jakub published the artcileNMR and IR study of kaolinite intercalation compounds with benzylalkylammonium chlorides, Safety of N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Applied Clay Science (2013), 426-432, database is CAplus.

Novel intercalation compounds of kaolinite with selected benzylalkylammonium chlorides, obtained using methoxy-kaolinite as a precursor, were characterized by ¹³C, ²⁷Al, and ²⁹Si solid-state NMR and IR (FTIR) spectroscopy. The analyses allowed the confirmation of both the formation and structure of precursors (kaolinite-DMSO and methoxy-kaolinite), as well as the intercalation compounds According to the ¹³C CP-MAS NMR spectra of the derivatives with benzyltrimethylammonium chloride (B1), the Me groups of the mols., arranged in a monolayer, were keyed into the ditrigonal holes of the kaolinite tetrahedral sheet. The local environment of internal carbons of benzyltributylammonium chloride (B2) Bu chains was mostly perturbed during intercalation. In turn, the structure of the benzyldimethylhexadecylammonium chloride (B5) after intercalation was changed from the solid-like to liquid-like conformation with an increase of gauche conformers, which was attested both by ¹³C CP-MAS NMR and FTIR. The ¹³C CP-MAS NMR anal. confirmed that the methoxyl groups attached to the octahedral surface of methoxy-kaolinite were not affected by intercalation. The ²⁷Al and ²⁹Si MAS NMR did not show any significant distortion of the Al-octahedra and Si-tetrahedra after intercalation of the organic salts. The IR analyses indicated an increased amount of intercalated water with the increase of initial salt concentration

Markus, Astrid published the artcileMicrobial degradation of 4-chlorophenylacetic acid. Chemical synthesis of 3-chloro-4-hydroxy-, 4-chloro-3-hydroxy- and 4-chloro-2-hydroxyphenylacetic acid, Safety of 3-Chloro-4-hydroxyphenylacetic acid, the publication is Hoppe-Seyler’s Zeitschrift fuer Physiologische Chemie (1982), 363(4), 431-7, database is CAplus and MEDLINE.

Pseudomonas CBS 3 converts 4-chlorophenylacetic acid partly into 3-chloro-4-hydroxy-, 4-chloro-3-hydroxy-, and 4-chloro-2-hydroxyphenylacetic acid by the action of monooxygenases. However, these compounds are not intermediates in the degradation of 4-chlorophenylacetic acid. Pseudomonas CBS 3 cannot grow with 3-chloro-4-hydroxy- and 4-chloro-3-hydroxyphenylacetic acid as sole C sources. 4-Chloro-2-hydroxyphenylacetic acid is slowly degraded, forming 4-chloro-2,3-dihydroxyphenylacetic acid. The actual degradation of 4-chlorophenylacetic acid seems to be initiated by the attack of a dioxygenase. The syntheses of 4-chloro-3-hydroxyphenylacetic acid and of 4-chloro-2-hydroxyphenylacetic acid are described.

Martyanov, Igor N. published the artcilePhotocatalytic Oxidation of Gaseous 2-Chloroethyl Ethyl Sulfide over TiO₂, Recommanded Product: 1,2-Bis(2-chloroethyl)disulfane, the publication is Environmental Science and Technology (2003), 37(15), 3448-3453, database is CAplus and MEDLINE.

Photocatalytic oxidation of gaseous 2-chloroethyl Et sulfide (2-CEES) over TiO₂ illuminated with UV light and maintained at 25° or 80° in air has been investigated. 2-CEES was found to suffer progressive oxidation to yield ethylene, chloroethylene, ethanol, acetaldehyde, chloroacetaldehyde, di-Et disulfide, 2-chloroethyl Et disulfide, and bis(2-chloroethyl) disulfide as the main primary intermediates, and water, carbon dioxide, sulfur dioxide, surface sulfate ions, and hydrogen chloride as the final products. Trace concentrations of gaseous 2-chloroethanol, ethanesulfonyl chloride, Et thioacetate, and considerable amounts of acetic acid, crotonaldehyde, Me acetate, and Me formate were also detected in the gas phase during the photooxidation conducted at 80°. An increase in temperature from 25° to 80° accelerates formation of gaseous ethanol, acetaldehyde, chloroacetaldehyde, di-Et disulfide, 2-chloroethyl Et disulfide, and bis(2-chloroethyl) disulfide but suppresses ethylene and chloroethylene production at initial stages of the process. Some aspects of the possible reaction mechanism leading to this wide array of intermediates and final products are discussed.

The tabulated I were prepared by heating the substituted salicylaldehyde with PhNH2 in PrOH and crystallized from the solvent shown. 3,5,2-BrCl(HO)C6H2CHO, m. 102.5-3.5° (CCl4), and its 5,3,2-isomer, m. 86° (CCl4), were prepared by halogenation of the corresponding 5-substituted salicylaldehyde in AcOH. The colors listed in the table were shown by the powd. compound on white paper. The absorption spectra of these powders were also obtained. [TABLE OMITTED] The introduction of halogen or NO2 shifts the absorption of the I (R3 = H) (II) into the visible region and increases it, whereas the substituents have little effect on the absorption spectra of I (R3 = Me). Evidently, the substituents promote structure IIb. In HCONMe2 solution unsubstituted or monohalogenated II have λmax. at 272 and 339 mμ, but disubstituted II show λmax. in the visible region, with II (R1 = NO2, R2 = Br; R1 = H, R2 = NO2; or R1 = NO2, R2 = H) showing 2 such maximum
