HMX and PETN explosives are the most important and usable explosives in the military and defense industries and possess wide range of applications for military as well as commercial applications. Numerous difficulties are encountered during the processing, conveying and storage of powders which are all attributed to their electrostatic charging. Indeed, charged powders could cause damage rangin...
RAFT-made poly(ionic liquid) chains (PIL), poly(1-[2-acryloylethyl]-3-methylimidazolium bromide) (Poly [AEmim][Br]), have been mixed with a ionic liquid (IL), namely butylmethylimidazolium chloride ([C4mim][Cl].) The similarities in terms of structure and polarity these molecular macromolecular imidazolium derivatives led to homogeneous transparent solutions. influence the chain molar mass conc...
Abstract Waste tyre pyrolysis gasoline (WTPG) contain significant amount of aromatics such as benzene, toluene and xylenes (BTX) thus provide a good source for these value-added chemicals. Separation from aliphatic media obtained in WTPG naphtha is done commercially by solvent extraction using volatile organic solvents sulfolane (SUF), dimethylformamide (DMF) diethylene glycol (DEG). The high c...
A new kind of ionic liquid based on the complexation of dipropyl sulfide (DPS) and AlCl3 has been prepared. The equivalent concentration of AlCl3 in the ionic liquid is as high as 2.3 M. More importantly, it is highly fluidic and exhibits an ambient ionic conductivity of 1.25 × 10(-4) S cm(-1). This new ionic liquid can be successfully used as an electrolyte for electrodeposition of aluminum.
benzo[b][1,4]oxazines have been synthesized in good to excellent yields in the presence of the ionic liquid 1-butyl-3methylimidazolium bromide [bmim]Br under relatively mild conditions without any added catalyst, the reaction workup is simple and the ionic liquid can be easily separated from the product and reused. Keywords—Isocyanide, Benzo[b][1,4]oxazines, Multi-component reactions, [bmim]Br,...
A room-temperature ionic liquid containing macrocyclic compound pillar[5]arene in its core was synthesized. The ionic liquid showed high thermal stability, moderate ionic conductivity and solvent-free complexation ability with the guest tetracyanoethylene.
We study the effective polarity of an air/liquid-mixture interface by using interface-selective heterodyne-detected electronic sum frequency generation (HD-ESFG) and vibrational sum frequency generation (HD-VSFG) spectroscopies. With water and N,N-dimethylformamide (DMF) chosen as two components of the liquid mixture, the bulk polarity of the mixture is controlled nearly arbitrarily by the mixi...
a simple and efficient one-pot method for the preparation of aromatic iodides has been developed by sequential diazotization–iodination of aromatic amines employing sodium nitrite and sodium iodide in the presence of acidic ionic liquid n-methyl-2-pyrrolidonum hydrosulfate ([h-nmp]hso4). the diazonium salts that are formed by this ionic liquid are stable at room temperature and react rapidly wi...
