N,N-diethylethanaminium-2-(sulfooxy) ethyl sulfate was synthesized and used as  an efficient, green, and recyclable catalyst and solvent for the nitration of aromatic compounds by nitric acid at 80oC

The reaction of tetranitromethane with the tyrosine residues of the pituitary glycoprotein hormones, luteinizing hormone (LH) and thyroid-stimulating hormone (TSH) has been compared. The total reaction products were inactive if sufficient reagent was used. Although polymer formation is a major reaction, nitrated LH monomer was obtained which was then separated into its a and /3 subunits and a f...

a novel and safe method for nitration of phenols, anilines and other aromatic compounds has beenfound to be feasible with alumina sulfuric acid (asa) as catalyst and mg (no3)2.6h2o as nitrating agent inneat water as solvent. the use of water makes this method compatible with the green chemistry approach

The effect of the selenium-containing compounds selenomethionine, selenocystine and ebselen [2-phenyl-1,2-benzisoselenazol-3(2H)-one] on the oxidation of dihydrorhodamine 123 caused by peroxynitrite and on the nitration of 4-hydroxyphenylacetate by peroxynitrite was studied in comparison with their sulphur analogues methionine, cystine and ebsulfur [2-phenyl-1,2-benzisothiazol-3(2H)-one]. The s...

Nitrocellulose is cellulose that titrated into an ester polymer which can be used as a major component in several types of ammunition and explosives other materials. Hemp (Boehmeria nivea) type fiber plant rich thrives Indonesia. Until now, the need for nitrocellulose Indonesia still imported, even though there lot potential exploited, one by synthesizing from hemp plant. One many uses derivati...
