A analysis of sodium lignosulphonate functional groups at all levels, effects of different fractions of lignin sulfonate dispersing pulverized coal role by studying the impact of lignin sulfonate coal-water interface to reveal the nature of the dispersion mechanism of action for the development and research lignosulphonates provide experimental data and theoretical basis.Preparation and Application of Hydrogel modified sodium lignosulphonate. Lignin sulfonate is one of the most important byproducts paper industry alone there are hundreds of tons per year to produce lignin sulfonate, only a part of the received little use, therefore, actively develop lignin sulfonate products, continue to broaden its range of applications, both environmentally friendly, but also conducive to the use of resources. Polymer hydrogels are a class swells in water, but not soluble in water, with functional three-dimensional network molecular structure of materials, polymer hydrogels have important in agriculture, construction, pharmaceutical industry, biotechnology and other applications. Hydrogel by source into synthetic polymer hydrogels and
natural polymer hydrogels, sodium lignosulphonate manufacturing synthetic polymer hydrogel
materials mainly from the oil industry, is a non-renewable resource, and such hydrogels biodegradable mostly poor, in the lack of resources, environmental protection imminent today, natural polymer
hydrogels with a long-term strategic significance of research and development work.
A three-dimensional network structure of lignosulfonate molecules rich in hydroxyl, carboxyl, sulfonic acid group, a hydrophilic group, is a good theoretical Hydrogel materials. This paper focuses on the
development of the use of lignin sulfonate, sodium lignosulphonate manufactured hydrogel from the start, in the removal of reducing sugars lignin sulfonates, lignin sulfonates and the preparation of the hydrogel-research, developed a can effectively reduce the lignin sulfonate method of reducing sugar and successfully prepare a no external crosslinking agent, a good swelling hydrogel modified lignin
sulfonate and use the modified lignin sulfonate prepared hydrogels prepared silver / modified lignin sulfonate hydrogel nanocomposites, will also apply to the modified lignin sulfonate hydrogel drug
delivery, studied the effect of modified sodium lignosulphonate sustained release of ferulic acid hydrogel piperazine. Studies have shown that by acid hydrolysis - salting method can effectively reduce the lignin sulfonate commercially in sugar. Optimal operating conditions for this method is: that the quality of lignin sulfonate 2% by mass solution, the quality of the sulfuric acid is added the total mass of
11.78%, 80oC hydrolyzed for 4 hours, the total mass salting 20% by mass sodium chloride.
After treatment with hypoglycemic lignin sulfonate as raw material, through oxidation, modified to obtain a modified sulfonated lignin sulfonate. Modified lignin sulfonate molecule phenolic hydroxyl content carboxyl, sulfonic acid were increased by 29%, 3.4%, 9.7%. Through the modification of sodium lignosulphonate. After heat treatment, the modified lignin sulfonate under acidic conditions, and then sodium hydroxide solution, the solid was collected by suction filtration and washed with deionized water to neutral to obtain the modified lignin sulfonate i.e. hydrogel.
