“…We also propose the catalytic reactions to be conducted in a magnetic reaction zone. In the conventional ammonia production case, the reactor must be able to operate at high temperature (400-500 o C) and pressure (150-300 atm) environments to ensure the reaction can be done successfully [3,4]. Another important parameter that needs to be considered is the appropriate ratio of reactant gas supply.…”

Abstract. Ammonia production is a capital-intensive industry as it requires high temperature (400-500 o C) and also high pressure (150-300 bar) for its daily operations. An earnest effort was made to synthese ammonia gas using an in-house designed microreactor. The production of ammonia was carried out in a magnetic field reaction zone, with the reaction temperature of 30°C -280°C and ambient operation pressure. Mn 0.8 Zn 0.2 Fe 2 O 4 nanoparticles, synthesized using the sol gel method, were used as the catalyst for the ammonia synthesis. XRD confirmed the single phase ferrites and FESEM images revealed nanofibre-like morphology when sintered at 700 o C in argon gas. Electron diffraction was performed using HRTEM and obtained diffraction patterns confirmed the crystal structure of the catalyst. By using the Kjeldahl method it was found that the reaction carried out in 1 Tesla magnetic field gave approximately 46% ammonia yield. The proposed new method could be appealing for ammonia manufacturers due to highly economical implication which may offer urea producers a potential contender in the competitive market place.

The anionic polymerization of five-membered cyclic carbonates fused to a cyclohexane ring, that is, the trans-and cis-cyclohexane-1,2-diyl carbonates (trans-and cis-1, respectively), were examined as a model polymerization example to reveal the origin of the unusually good polymerizability of the previously reported methyl 4,6-O-benzylidene-2,3-O-carbonyl-a, D-glucopyranoside. The tert-BuOK-initiated anionic polymerization of trans-1 produces polymers with M n values of 11 000, whereas no polymeric products were obtained from cis-1. The structure of the poly(trans-1) was confirmed by comparison with the model carbonate (2) based on the 13 C NMR spectra as well as the hydrolysis experiments. The poly(trans-1) form essentially consists of polycarbonate units; therefore, the polymerization of trans-1 was not accompanied by any decarboxylation. The thermodynamic parameters for the polymerization of trans-1 were estimated to be DH p 1 ¼ À23 kJ mol À1 and DS p 1 ¼ À63 J K À1 mol À1 .

Abstract:The trans-dihydroxylation of olefins occurs efficiently by aqueous hydrogen peroxide catalyzed by p-toluenesulfonic acid at 50 8C, allowing the catalyst reuse and an outstanding substrate functional group tolerance such as tert-butoxycarbonylamino (BocNH), benzyloxycarbonylamino (CbzNH), benzyloxy (OBn), tosyloxy (OTs), hindered ketal, (2-trimethylsilyl)ethoxymethoxy (OSEM), benzylamino (NBz), benzyloxy (OBz) and free amino acid.
