Influence of bagasse magnesium lignosulfonate with relative different molecular weight on performance of cement mortar;

There are some problems during producing magnesium lignosulfonate powder a kind of cheap and efficien surfactant from red liquor.

The structure characteristic parameter of non-woody magnesium lignosulfonate(ML) are studied by IR and other means in comparison with woody calcium lignosulfonate(CL).

Iron(II) tetrasulfophthalocyanine (FeTSPc) as the mimetic enzyme of peroxidase was used to catalyze the synthesis of a conducting polyaniline (PANI)/lignosulfonate (LGS) complex in the presence of LGS template system.

AM/AMPS/calcium lignosulfonate graft copolymer as filtrate reducer for mud was synthesized from calcium lignosulfonate,acrylamide and 2-acrylamido-2-methylpropanesulfonic acid.

Using amine and lignin sulfonate as raw material, a new surfactant-lignin-amide was synthesised by acidylation.

After the sulfonation of lignin extracted form black papermaking liquor,a lignin sulfonate can be made,which may be used as tar emulsifier and flocculant.

Experiment research on synthesis of additive by chemical conversion of lignin sulfonate introduced.

By sulfonation and fasculation reaction,sodium lignin sulfonate was modified as a dispersant(GCL3S) of coal water slurry(CWS).

The water soluble dispersant agent, which the backbone was sodium cellulose sulfate and sodium lignin sulfonate, was prepared using cane dregs and fuming sulfuric acid as raw material .

By the idea of green manufacturing and green products, modified lignin polymer with a new structure were designed and synthesized using the thesis industry by-products– sodium lignin sulfonate through an experiment and also was discussed its application performance in the paper,.
