Abstract

Ni/MgO catalyst has been designed as bifunctional catalyst for condensation reaction of furfural and acetone followed by hydrogenation reaction to produce C8-C13 alkane derivatives in one step reaction. Ni/MgO catalyst was prepared by wet impregnation methods using Ni(NO3)2.6H2O and MgO as supporting material. The charcterization by X-ray diffraction (XRD) showed the characteristic of Ni on 2q = 44,27o; 51,59o and 75,89o. Isoterm adsorpsi using N2 gas gave the decreasing surface area of MgO and forming microporous structure. The activity test of the catalyst was carried out using furfural and acetone (1:1) in autoclave bath system, heated at 100-180oC for 7-8 hours in the presence of water. Ni/MgO catalyst showed the good activity when hydrogenation reaction performed at 150oC lead to the conversion of alkane derivatives in 95.69%. Characterization of the product by GC-MS showed the formation of 4-(2-furanyl)-2-butanone; 1,5-di(2-furanyl)-3-pentanone and 1,5-di(2-furanyl)-3-(1-pentenone) from reduction of C=C alkene of furfurylidene acetone.

Abstract

Hydrodeoxygenation (HDO) reaction of furfural derivatives have widely studied because these reaction produce saturated alkane which potensial for renewable fuels. Nickel based catalyst impregnated in to ZrO2-SiO2 (Ni/ZrO2-SiO2) was prepared and its activity is evaluated for HDO of furfurilidene aceto (FAc) and difurfurilidene acetone (F2Ac). Ni/ZrO2-SiO2 catalys was prepared from Ni(NO3)2.6H2O with 10% Ni loading over ZrO2-SiO2 by wet impregnation method. Characterization using X-ray showed the diffraction of Ni detected at 2θ = 44.42, 51.73, and 76.26. Catalyst activity for HDO of FAc and F2Ac was carried out at 200oC for 2 hours in batch system. According to gas chromatography analysis, the conversion of product is 100% with selectivity for 2-octanol and dodeka-6-ene is 88,22% and 2,99%, respectively.

Abstract

Although photolysis of phenyazide has been widely reported to give 3H-azepine, the thermal deoxygenation reaction of alkylnitrobenzene derived similar products hitherto unexplored. Novel synthesis of 2-methoxy-3H-azepine derivatives was carried out using alkylnitrobenzene with tributylphosphine (Bu3P) reacted at 150°C for 24 hours in the presence of methanol. Reaction of m-nitrobenzene with the above methods gave two isomers of 3H-azepine, namely, 2-methoxy-6-methyl-3H-azepine and 2-methoxy-4-methyl-3H-azepine in 61%. Reaction of 2,3-dimethylnitrobenzene with Bu3P afforded the three isomers, that is, 2-methoxy-6,7-dimethyl-3H-azepine; 2-methoxy-3,4-dimethyl-3H-azepine and 7-methoxy-5,6-dimethyl-4H-azepine. Reaction of 3,5-dimethylnitrobenzene gave the sole product of 2-methoxy-4,6-dimethyl-3H-azepine in 42%. In contrast, reaction of 2,6-dimethylnitrobenzene didn’t give any product because the steric effect of methyl groups attached on C2 and C6. Structure elucidation of all novel products have confirmed by HETCOR.
