The syringyl/guaiacyl (S/G) ratio of Eucalyputs grandis lignin was determined and its relation with kraft pulping parameters was studied. Twenty one wood samples obtained from 10-year-old trees grown in the same place were analyzed using Py-GC-MS to determine the syringyl/guaiacyl (S/G) ratio. The samples were pulped to the same final lignin content (Kappa number 18) obtaining pulp yields between 48.8% and 54.3%. Relationships were observed between pulp yield and S/G ratio (r = 0.51) also between alkali charge used in pulping and S/G ratio (r = -0.60).  © 2014 Elsevier B.V.  aCONTENIDO DE LIGNINA  aCROMATOGRAFÍA DE GASES  aEUCALYPTUS GRANDIS  aFOREST AND FORESTRY  aFORESTACIÓN1 aGALETTA, A.1 aVINCIGUERRA, V.1 aRESQUIN, F.1 aMENÉNDEZ, P.  tJournal of Analytical and Applied Pyrolysis, 2014gv.107, p.284-288.
