Kinetics parameter values of methyl ricinoleate nitration (rate constant, reaction order and the rate of reaction) have been determined. Nitration was carried out with both concentrations of HNO3 and acetic anhydride in excess to the concentration of meth... see more

Determinations of the temperature effect on glycerol nitration processes have been done with two methods: the HYSYS predictions and the laboratory experiment. The aim of this study was to compare prediction method and laboratory experiment method. The hig... see more

Determination of the optimum reaction time, activation energy (Ea) and frequency factor (A) of methyl ricinoleate nitration has been done. The nitration was conducted with the mole ratio of methyl ricinoleate to HNO3 of 1:15. The reaction was conducted at... see more

In the present study, a kinetic model of nitration between glycerol and nitric acid was developed. The presented model describes three controlling reactions model used elementary reactions consisting of three reversible reactions. The model utilizes first... see more

The paper describes the effect of velocity ratio for mixing glycerol nitration in microchannel hydrodynamic that focused on the stream width. The method used are experimental and theory modeling of hydrodynamic fluid flow focused on predicting behavior st... see more

Nitration of methyl ester from mahogany oil (Swietenia mahagoniLinn) can be produced by Methyl Ester Nitrate (MEN), an additive that is useful for increasing Cetane Numbers in diesel fuel. This study aims to determine the yield of MEN that can be produced... see more

The 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (HNIW), a high energy material with cage structure, is considered as the most powerful explosive today. It is usually prepared via nitration with concentrated nitric and sulphuric acid, but th... see more

Aim. To establish patterns of starch nitration process, allowing to justify the choice of the composition of the nitrating mixture and the regime parameters of nitration. Methods. The degree of nitration was expressed in terms of the nitrogen content in t... see more

Derivatization of 5,11,17,23-tetra-t-butyl-25,26,27,28-tetrahydroxycalix[4]-arene to 5,11,17,23-tetra-amino-25,26,27,28-tetrabutoxycalix[4]arene compound via etherification, ipso nitration, and reduction reactions, respectively has been conducted. The eth... see more
