Fast Pyrolysis of Lignins
Three lignins: Indulin AT, Lignoboost, and Acetocell lignin, were characterized and pyrolyzed in a continuous-fed fast pyrolysis process. The physical and chemical properties of the lignins included chemical composition, heat content, ash, and water content. The distributed activation energy model (DAEM) was used to describe the pyrolysis of each lignin. Activation energy distributions of each ...
متن کاملPhenolic Moieties in Lignins
The use of 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane as a phosphitylation reagent in quantitative 31P NMR analysis of the hydroxyl groups in lignins has been thoroughly examined, and an experimental protocol recommended for spectra acquisition has been developed. Quantitative analysis of six “standard lignins” gave results comparable to those obtained by other methods of analysis. Exc...
متن کاملEsca (black measles) of grapevine. An overview
More than 100 years ago a grapevine disease of unknown etiology was recognized in France and California, where it was called “folletage” (Ravaz, 1898) and “sunstroke” respectively (Anonymous, 1895). In both cases the disorder was considered to be due to a physiological condition resulting from what was called “abrupt changes in the bottom water level.” Research on the pathological nature of the...
متن کاملAre lignins optically active?
The accepted derivation of lignins from non(enzymatically)-controlled radical coupling reactions has been recently challenged, and it is relevant to ascertain unequivocally whether lignins are or are not (as normally assumed) optically active. Two approaches were used. First, DFRC (derivatization followed by reductive cleavage) dimers derived from beta-5- and beta-beta-units in pine lignins, wh...
متن کاملthe impact of skopos on syntactic features of the target text
the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...
