Reaction of Poly (2-methyl- N-vinylimidazole) with n-Alkyl Bromide

Swelling Characterization of Nanocomposite Hydrogels of Poly (acrylamide-N-vinylimidazole)

In this study, a hydrogel composed of acrylamide (AAm) with N-vinylimidazole (NVI) as co-monomer, with a cross-linker such as N, N` Methylenebisacrylamide and potassium peroxodisulfate as an initiator solution was prepared. Poly (AAm/NVI) hydrogels were synthesized by free radical solution polymerization. Swelling experiments were performed in water at 25°C, gravimetrically. Here, it was of...

Synthesis, characterization and reactivity ratio study of poly(di(tri-n-butyltin) citraconate-co-N-vinylimidazole).

The organotin monomer di(tri-n-butyltin) citraconate (DTBTC, I) was synthesized. Subsequently this monomer was copolymerized with N-vinylimidazole (VI) using a free radical technique. The overall conversion was kept low (< or = 14% wt/wt) for all studied samples and the copolymer composition was determined from tin analysis using the Gilman and Rosenberg method. The synthesized monomer and copo...

1-Methyl-3-n-tetra­decyl­imidazolium bromide monohydrate

In the title ionic liquid salt hydrate, C(18)H(35)N(2) (+)·Br(-)·H(2)O, the side chain in the cation has an extended conformation. The crystal structure is stabilized primarily by O-H⋯Br hydrogen bonds. C-H⋯O and C-H⋯Br inter-actions are also present.

N-(2-Bromo­benz­yl)cinchoninium bromide

The title compound {systematic name: 1-(2-bromo-benz-yl)-5-ethenyl-2-[hy-droxy(quinolin-4-yl)meth-yl]-1-aza-bicyclo-[2.2.2]octan-1-ium bromide}, C(26)H(28)BrN(2)O(+)·Br(-), is a chiral quater-nary ammonium salt of one of the Cinchona alkaloids. The planes of the quinoline and of the bromo-benzyl substituent are inclined to one another by 9.11 (9)°. A weak intra-molecular C-H⋯O hydrogen bond occ...
