The studies include new organic reactions of isocyanide, carbon monoxide and carbene, which are characterized by a carbon atom carry­ ing lone-pair electrons. Reactions catalyzed by copper compounds as well as other Groups IB and IIB metal compounds constitute the central featl1re of tIl':' present studies. New organic reactions of isocyanidE' without catalysts are also presented. The author expresses his deep gratitude to Professor Takeo Saes'Usa for his constant guidance and encouragement throughout the work. Grateful acknowledgement is also made to Dr. Yoshihiko Ito for his valuable advice an? dis cussions during the course of studies. The author wishes to express his deep appreciation to Messrs.

Eng., 36(7), 1051-1056 (2019) pISSN: 0256-1115 DOI: 10.1007/s11814-019-0294-y eISSN: 1975-7220 INVITED REVIEW PAPER INVITED REVIEW PAPER Selective synthesis of acetonitrile by reaction of ethanol with ammonia over Ni/Al2O3 catalyst Ye-Seul Jeong, Sang Hee An, and Chae-Ho Shin† Department of Chemical Engineering, Chungbuk National University, Cheongju, Chungbuk 28644, Korea (Received 28 March 2019 • accepted 7 May 2019) AbstractA highly selective synthesis of acetonitrile was carried out by the reaction of ethanol with ammonia on a 10 wt% Ni/Al2O3 catalyst. The conversion of ethanol and selectivity to acetonitrile, ethylene, and monoethylamine were examined by varying experimental parameters such as ammonia partial pressure, reaction temperature, and space time. The increase in the ammonia partial pressure led to a considerable decrease in the conversion and small increase in the acetonitrile selectivity up to a molar ratio of NH3/ethanol of 3, followed by almost constant values. The partial reaction order of ethanol obtained by controlling the space time was one, while that of ammonia was negative, 0.4. The deacti- vation behavior of the catalyst after 100 h on stream reaction at 230 oC was analyzed by X-ray photoelectron spectros- copy and temperature programmed oxidation of the catalyst used. The catalyst deactivation was attributed to the gradual formation of nickel carbonitride on the catalyst surface. Keywords: Acetonitrile, Nickel Catalyst, Ethanol, Carbonitride, Deactivation INTRODUCTION face in a metallic state, so that a gradual deactivation is observed. The development of a highly selective acetonitrile synthesis catalyst Acetonitrile is used mainly as a solvent of extractive distillation, by controlling these simple experimental parameters is important isolation of butadiene from C4 hydrocarbons, in battery applica- to guide the development of novel catalysts in the future.

General methods, equipment and parameters Chemicals were purchased from Sigma Aldrich, TCI, Acros Organics, AppliChem, and Riedel-de Haën and used without further purification. Solvents were purchased from Sigma Aldrich, Fischer Chemicals or Acros Organics and stored under argon. Delamination tests were performed under argon atmosphere in Schlenk tubes. Powder X-ray diffraction (PXRD) patterns were collected using a Stoe StadiP system in transmission mode. Samples were prepared in flat base sample holders. 3° Step wide and 80 sec per step exposure time were used. For measurements Cu Kα1 radiation (λ=0.15405 nm) was applied. Scanning electron microscope (SEM) analysis was performed on the SU8020 scanning electron microscope (HITACHI, Japan) with an accelerating voltage of 1-2 kV. Dried materials were sputtered with gold. Average particle size was estimated from 10-20 measurements. For nitrogen physisorption experiments a Belsorp-max system from MicrotracBEL (Japan) was used. The samples were additionally activated at 150 °C for 18 hours prior to measurements. The analysis was performed at 77 K. Solid state infrared (IR) spectroscopy was performed using the Vertex 70 instrumentation of Bruker in DRIFT-IR mode. Samples were mixed with dry KBr (0.5 mg MOF + 100 mg KBr) directly before measurements.

    PHYSIOLOGICAL A.c'lD CHEMICAL ECOLOGY Structure Activity Relationships of Phenyl Alkyl Alcohols, Phenyl Alkyl Amines, and Cinnamyl Alcohol Derivatives as Attractants for Adult Corn Rootworm (Coleoptera: Chrysomelidae: Diabrotica spp.) l 2 RICHARD J. PETROSKI AND LESLIE HAMMACK Environ. Entomol. 27(3): 688-694 (1998) ABSTRACT In field trapping tests, phenyl alkyl amines and phenyl alkyl alcohols with 2-carbon side chains attracted significantly more adult females of the northern com rootworm, Diabrotica barberi Smith & Lawrence, than did phenyl alkyl amines or phenyl alkyl alcohols with 1-, 3-, or 4-carbon side chains. Both sexes ofnorthern com rootworm were attracted to 2-phenyl-l-ethylamine in greater numbers than to 2-phenyl-l-ethanol, whereas the latter was the better attractant in the case of female western com rootworm, Diabrotica virgifera virgifera LeConte. Differences in attractancy between the 2 compounds were attributed to differences in atomic charge; electrostatic charge was calculated to be -1.10 on the nitrogen atom in 2-phenyl-l-ethylamine but only -0.70 on the oxygen atom in 2-phenyl-l-ethanol. Northern com rootworms responded in Significantly greater numbers when the 2 compounds were blended than when a dose of either compound was increased 10-fold. This observation does not support the idea that 2-phenyl-l-ethylamine substitutes for 2-phenyl-l-ethanol at a phenyl alkyl alcohol recognition site. In the case of cinnamyl alcohol derivatives, cinnamyl alcohol attracted the most northern corn rootworms, but cinnamaldehyde attracted the most western corn rootworms ofboth sexes. Male western corn rootworms responded to only cinnamaldehyde.
