Abstract:Predstavljene so različne vrste hidrofobnih lesnih lipidov, ki so možni povzročitelji onesnaženja v papirniških sistemih, prav tako pa tudi analitske metode za njihovo karakterizacijo. Podani so rezultati določitve vsebnosti trigliceridov, sterolnih estrov, sterolov, maščobnih in smolnih kislin v smrekovih in bukovih sekancih, ki so pomembna vhodna surovina v celulozno-papirni industriji. Izdelana je primerjava različnih analitskih tehnik, in sicer ekstrakcije na trdni fazi (SPE), tankoplastne kromatografije (TLC), gelske porazdelitvene kromatografije (GPC) in plinske kromatografije (GC); navedene so njihove prednosti in pomanjkljivosti pri določanju kemične sestave in lesnih ekstraktivov.

Title:Characterization methods for wood extractives
Abstract:Various types of hydrophobic wood lipids, believed to behave detrimentally in papermaking , are presented, as well as different analytical methods for their chemical characterization. A determination of triglycerides, steryl esters, sterols, fatty and resin acids in spruce and beech chips (important raw materials in pulp and paper industry) was performed. A comparison of results, obtained by solid phase extraction (SPE), thin layer chromatography (TLC), gel permeation chromatography (GPS) and gas chromatography (GC) was made. Advantages and drawbacks of individual analytical techniques were established.
Keywords:wood extractives, chemical characterization, spruce chips, beech chips, chromatography, methods, articles
