text: Kraft lignin (KL )
text: Softwood kraft lignin (SKL) contains different types of hydroxyl groups, which were reported to have different reactivity for esterification (Thielemans and Wool, 2005).
text: The adopted solvent fractionation procedure of LignoBoost Kraft lignin (KL) yields five different fractions, four of which are soluble in organic solvents that are considered green and benign, the fifth fraction being the insoluble residue.
text: Industrially, lignin can be produced from different processes, obtaining the corresponding Kraft lignin (KL), Soda lignin, Lignosulphonates (LS), Organosolv lignins (OS), Steam-explosion lignin, and enzymatic hydrolysis lignin (EHL).
text: Carbon fibers, activated carbons, and carbon black are some of the products that can be obtained by thermochemical conversion of kraft lignin (KL) (Rosas et al. 2014).
text: The main lignin types available in relevant quantities are lignosulfonates (LSs), kraft lignin (KL), organosolv lignins (OSLs), and biorefinery lignins that differ notably in their chemical structure, molecular weight, and purity, which in turn determine their solubility and organoleptic qualities.
text: In the present study, six organic solvents that are commonly used in the paint industry (1-butanol, 1-methoxy-2-propanol, 2-propanol, butyl acetate, propylene glycol monomethyl ether acetate, and diethylene glycol monobutyl ether) were tested for their ability to dissolve two distinct lignins: an industrial kraft lignin (KL) and a pilot-scale organosolv lignin (OL).
text: In the case of kraft lignin (KL), the influence of some changes in the synthetic process was also tested: applied voltage, pretreatment in air or not, and the addition of a small amount of Ketjen black.
text: Kraft lignin (KL) was modified with 3-chloro-2-hydroxypropansulfonic acid sodium salt (CHPSS) and glycidyltrimethylammonium chloride (GTMAC) in an aqueous solution simultaneously.
text: Other types of isolated lignins such as softwood kraft lignin (SKL) are also commercially available.
text: These two selected technical lignins, that is, a softwood-based lignosulfonate (SLS) and a softwood-based kraft lignin (SKL), were chosen on the basis of their significant difference in amphiphilic character and water solubility.
text: Organic solvent fractionation of commercially available softwood kraft lignin (SKL, Indulin-AT, WestRock, Glen Allen, VA) was carried out by sequential extraction with organic solvents based on a published procedure.
