Determination of the main aliphatic carboxylic acids in kraft black liquors by high- performance liquid chromatography-mass spectrometry
نویسندگان
چکیده
In kraft pulping, wood polysaccharides are subjected to the end-wise degradation (i.e., the peeling reaction) under alkaline conditions with the simultaneous formation of a large number of water/alkali-soluble hydroxy monoand dicarboxylic acids together with formic and acetic acids [1-3]. The versatile analysis of organic material in black liquor is of a great importance, for example, for monitoring the progress of this delignification process. Detailed chemical analysis of the main aliphatic acids comprises a current topic for several reasons.

Identification of organic acids in bayer liquors by GC-MS: a comparison using butylation and methylation.
Two well known derivatization methods, butylation and methylation, are compared by gas chromatography (GC)-mass spectrometry (MS) to identify organic acids in Bayer liquors. These two derivatization methods should be combined together for the determination of the carboxylic acids. Twenty-four organic acids are identified by GC-MS and 13 organic acids are firstly found in Bayer liquors. The rete...

The antioxidant activity of the phenolic compounds present in industrial black liquors obtained from the two cooking processes (kraft and sulphite) used in Portugal to produce Eucalyptus globulus pulp was evaluated. The black liquors treated at several pH values were extracted with ethyl acetate. Phenolic fractions were further separated by liquid chromatography of the crude extracts of kraft l...
