As the binding agent in wood, lignin, is a natural polymer. Lignin is derived from the Latin word 'lignum', meaning wood. Lignin is an essential part of trees, It acts as an encrusting material and performs multiple functions that are essential to the life of the plant.
En realidad, existen dos variantes: el Sodium Lauryl Sulfate (Lauril Sulfato de Sodio o SLS) y el Sodium Laureth Sulfate (Lauret Sulfato de Sodio o SLES). Este último, empezó a incorporarse con más frecuencia a los productos al tener sustancias menos abrasivas para la piel. Sin embargo, y aunque ambos proceden del coco, la solución final ...

The high lignin content had the potential to make Sodium Ligno Sulfonate (SLS) Surfactants by reacting Lignin with Sodium Bisulfite. Isolation of Lignin From Black Liquor was carried out at room temperature of 30°C, using sulfuric acid (H 2 SO 4) and 1N NaOH. The purpose of this study was to characterize SLS formed both physically and chemically.
L'industrie du verre est également une grande utilisatrice de sulfate de sodium, avec une consommation d'environ 30 000 tonnes en 1990 aux États-Unis (4% de la consommation totale). Il est utilisé pour réduire la quantité de petites bulles d' air dans le verre fondu. Il contribue également à fluidifier le verre, et à prévenir la formation de mousse dans le …

time, sodium hydroxymethyl sulfonate/lignin mole ratio, and sodium concentration were investigated. Furthermore, previ-ous reports highlighted that the more sulfonated groups of lignosulfonates and greater the negative charge density, the greater the resulting corrosion eciency of the SLS [32, 33].
Sodium hydroxide solution (30%) was added when necessary, in order to maintain the pH between 12 and 12.5. This step, alongside vigorous overhead stirring, allowed for adequate dissolution of LS. In total, 18.1 parts by mass of sodium hydroxide solution (30%) were added, resulting in a final pH of 12.5.
