Separation of cellulose acetates by degree of substitution

Polymer, 2013
Abstract A liquid chromatographic method was developed allowing separating cellulose acetates (CA) with respect to degree of substitution (DS). The normal-phase gradient separation, which is based on an adsorption–desorption mechanism, uses a multi-step gradient of dichloromethane (DCM) and methanol (MeOH) on a bare silica column as stationary phase.

Determination of the degree of substitution, degree of amidation and degree of blockiness of commercial pectins by using capillary electrophoresis

Food Hydrocolloids, 2007
It is more and more realised that pectins are complex mixtures of many different molecules and research is directed towards the fractionation and characterisation of these pectic sub-populations. Since fractionation of pectins generally results in only low amounts of purified material, rapid characterisation methods using low amounts of samples are ...

Determination of the degree of the substitution of hydroxyethyl guar gum

Carbohydrate Polymers, 2008
Abstract An improved chemical method for the determination of the degree of the substitution of hydroxyethyl guar gum by mixed p -toluenesulfonic-acetic anhydride has been described. The hydroxyethyl groups are cleaved from modified galactomannans at 130 °C in the presence of excess mixed p -toluenesulfonic-acetic anhydride for 14 h, and then the ...
