The complexation behaviour of an imidazolium based ionic liquid surfactant (ILS) 3-methyl-1-dodecylimidazolium chloride, [C12mim][Cl], and its amide and ester functionalized counterparts 3-(2-(dodecylamino)-2-oxoethyl)-1-methyl-1H-imidazol-3-ium chloride, [C12Amim][Cl], and 3-methyl-1-dodecyloxycarbonylmethylimidazolium chloride, [C12Emim][Cl], with a model protein gelatin (G) in aqueous soluti...

In previous work by the authors, aspects of the surface chemistry connected with methyl chloride synthesis over an η-alumina catalyst have been examined. This communication considers a role for Group 1 metal salts to modify the catalytic performance of the well characterised η-alumina catalyst. Firstly, based on a previously postulated mechanism for the reaction of methanol on η-alumina, a mech...

The aim of the present study was to synthesis a series of phthalimides based on our previous works and examine their anxiolytic properties. Using a three steps process, phthalimides were prepared from the corresponding di-methyl phthalate derivatives. Phthalic anhydride was nitrated to produce 3-nitrophthalic acid. Ring closer of either 3-nitrophthalic acid or di-methyl phthalate with urea were...

In the hydrated title salt, C 7 H 12 N 5 S 2 + ·Cl − ·H O, asymmetric unit comprises one 2-amino-5-{(1 E )-1-[(carbamothioylamino)imino]ethyl}-4-methyl-1,3-thiazol-3-ium cation, chloride anion and water molecule of crystallization. The cation is nearly flat (r.m.s. deviation non-H atoms 0.0814 Å), with largest 0.1484 (14) Å observed for methyl atoms. crystal, cations are linked by O—H...Cl, N—H...
