ethylene bis-stearamide is one of the important acrylonitrile-butadiene-styrene ()abs)( polymer additives, which is used as lubricant, slip agent and mold release agent. in this research, ethylene bis-stearamide for abs application was synthesized using stearic acid and ethylene diamine under reflux condition. refluxing prevented ethylenediamine from evaporation and thus the initial molar ratio...

New Pd(II) and Pt(II) complexes of the type [M(bzoS)2(diamine)] {where M = or } from treatment one mole diamine ligands {diamine , phenanthroline (Phen), bipyridine (Bipy), ethylene (en), N,N′-dimethyl (dmen)} with [M(bzoS)2] complexes. The prepared were characterization by elemental analysis (CHN), molar conductivity, infrared spectroscopy, nuclear magnetic resonance proton (1H NMR). bzoS- lig...

A new water-soluble pyrene-containing fluorescent polymer, 1-{31-S-[poly(acryloyl ethylene diamine hydrochloride)-21-methyl propionic acid]}propionyloxy hexyloxy pyrene (P3) with defined structure, was designed and synthesized using the click reaction between thiol and a carbon-carbon double bond. The intermediate products P1 (S-1-dodecyl-S1-[poly(N-Boc-acryloyl ethylene diamine)-21-methyl prop...

Transparent, crack-free mesoporous silica sol–gel monolith 2 was prepared from the hydrolysis of Si(OMe)4 in MeOH containing ethylene glycol (HOCH2CH2OH). Gradual exposure of the product monolith 1 to MeOH/H2O and then H2O helps prevent cracking of the monolith. Direct reaction of chelating diamine H2N(CH2)2NH(CH2)3Si(OMe)3 with 1 gave diamine-grafted monolith 3. Imprint-grafting of monolith 1 ...

1HE GROWING CLINICAL interest in the action and metabolism of the catechol amines makes it highly desirable to re-evaluate existing methods for the quantitative determination of these substances in body fluids. In 1955 Persky (1) reviewed the subject, and, on the whole, his conclusion is still valid that the fluorometric determination of the catechol amines in body fluids is the most practical ...

Reaction of thiodiacetate anion (tda) with [Cu(TMEDA)(NO3)2] (TMEDA = N,N,N'N'-tetramethyl ethylene-diamine) in a stoichiometric ratio afforded the complex {[Cu(TMEDA)(tda)]·(H2TMEDA)(NO3)2·H2O} (1). When [Cu(TMEDA)(NO3)2] was added in excess, it yielded a μ-oxalato complex {[Cu2(TMEDA)2(μ-ox)(H2O)2](NO3)2·2CH3CN} (2). The reaction involves a facile room temperature desulfurization of the thiod...

Chlorin e6 is a tricarboxylic acid degradation product of chlorophyll a. Four chlorin e6 bis(amino acid) conjugates were regioselectively synthesized bearing two aspartate conjugates in the 13(1),17(3)- and 15(2),17(3)-positions, or at the 13(1),15(2)via an ethylene diamine linker. One additional conjugate bearing two different amino acids, lysine at 13(1)via an ethylene diamine linker and an a...
