Imidazolium chlorides with one or two carboxylic acid substituent groups, 1-methyl-3-alkylcarboxylic acid imidazolium chloride, [Me{(CH2)(n)COOH}im]Cl (n=l, 3), and 1,3-dialkylcarboxylic acid imidazolium chloride, [{(CH2)(n)COOH}(2)im]Cl (n=1, 3), have bee ...
The degrdn. of herbicides 4-chlorophenoxyacetic acid (4-CPA), 4-chloro-2-methylphenoxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) in aq. medium of pH 3.0 was comparatively studied by anodic oxi ...
Described are compounds that are capable of forming adlayers, said compounds comprising at least one headgroup A, an optional linker B, a polymer C, a terminal group D and an optionally present crosslinking group R, wherein the headgroup A is a compound of ...
This article provides insight into the various factors by which electroneg. substituents affect the kinetic acidity of arenes and, more specifically, naphthalenes. Both 1- and 2-(trifluoromethyl)naphthalenes were consecutively treated with an organometalli ...
This report describes the synthesis and supramolecular organization of a novel class of linear-dendritic block copolymers. The molecules, which are termed rodcoil dendrons, consist of a cholesterol moiety that is attached to L-lysine dendrons of three diff ...
N-Substituted (3S,4S)- and (3R,4R)-pyrrolidine-3,4-diols 9 and 10, respectively, were derived from (+)-L- and (-)-D-tartaric acid, respectively. Compounds 9k, 91, and 9m with the N-substituents, BnNH(CH2)(2), 4-Phc(6)H(4)CH(2)NH(CH2)(2) and 4-ClC6H4CH2NH(C ...
This review sums up the activity in the field of in situ product removal in whole cell bioprocesses over the last 20 yr. It gives a complete summary of ISPR operations with microbial cells and cites a series of interesting ISPR applications in plant and an ...
The electrogeneration of hydroxyl radicals was studied at a synthetic B-doped diamond (BDD) thin film electrode. Spin trapping was used for detection of hydroxyl radicals with 5,5-dimethyl-1-pyrroline-N-oxide and with salicylic acid using ESR and liq. chro ...
The influence of residual ethanol on metab. of food grade Gluconacetobacter xylinum I 2281 was investigated during controlled cultivations on 35 g/l glucose and 5 g/l ethanol. Bacterial growth was strongly reduced in the presence of ethanol, which is unusu ...
Aq. solns. of formic acid were exptl. investigated in a modified sweeping gas membrane distn. (SGMD) configuration. A thermostated sweeping gas was used in order to enhance the mass transfer performance. A new tubular module was designed and built for this ...
