Our objective in the present article was to use this model in a first step to optimize the cationization reaction on a laboratory scale extruder, and, in a second step, to extrapolate the results to an industrial scale extruder. We will show that the use of a theoretical model of reactive...
A theoretical model for the cationization of plasticized wheat starch in a modular seIf-wiping co-rotating twin screw extruder was developed. Our objective was to build a model which would be able to predict the evolution of the cationization reaction along the screws, in relation with the ...
Preparations of bovine serum albumin (BSA) were cationized by substituting anionic side chain carboxyl groups with polycationic aminoethylamide groups. Different degrees of substitution were obtained by varying the reaction time. Mice immunized with partially cationized proteins produced early increased level...

Analysis using NMR spectroscopy enables evaluation of reaction efficiency and regioselectivity of the material. The efficiency of the reaction, measured as the degree of substitution (DSNMR), can be estimated from the 1D 1H-NMR spectrum according to Eq. 1. To improve the accurateness of the pr...
Furthermore, the hemicelluloses isolated via Method 2 were rendered cationic by using glycidyltrimethylammonium chloride (GTMAC), and the process parameters for the cationization reaction were studied, including the water content, reaction temperature and time, molar ratio of GTMAC/hemicelluloses, and...
Factors affecting the cationization reaction of linen fabric were studied. These factors include Quat-188 concentration, NaOH concentration (or pH of the reaction medium in case of exhaustion method), reaction time and temperature as well as material to liquor ratio (in case of exhaustion method)...
Results obtained signify that: (a) optimum conditions for cationization of PCMC fabric are obtained when the Quat-188/sodium hydroxide molar ratio is 1/2 using the cold pad-batch method for 24 h; (b) the extent of cationization reaction, expressed as percent nitrogen, increases as the ...
Cationization modification of polysulfone microfiltration membrane by graft-polymerization and subsequent polymer reactionIn order to make polysulfone (PSF) microfiltration membrane to have the rejection selectivity, the microfiltration membrane of chloromethylated polysulfone (CMPSF) was first modified into ami...
