“…Some dispersants have been commercialized, such as naphthalene sulfonated formaldehyde condensates, sulfonated melamine formaldehyde polymers and the aminosulfonic acid series, etc. They are in the process of synthesis or use may result in undesirable environmental effects, as they can accidentally or intentionally release formaldehyde into the environment [ 4 , 5 , 6 , 7 , 8 ]. Therefore, an environmentally friendly and biodegradable additive is urged to be developed as a new high-performance dispersant for coal–water slurries using cheap and abundant natural renewable resources as raw materials.…”

A novel sulfonic-cellulose succinate half ester (S-CSHE) dispersant for coal–water slurry (CWS) was successfully synthesized using cotton linters, sulfamic acid and succinic anhydride in DMF by a one-pot synthesis. The effects of the synthetic condition of S-CSHE as a dispersant for CWS were studied. An S-CSHE with a maximum degree of substitution of 0.98 was obtained under these optimized conditions. The synthesized samples were characterized by GPC, FT-IR spectroscopy, 13C-NMR, and SEM. The molecular weight was from 2.2 × 103 to 1.2 × 104, revealed by GPC; FT-IR spectra analysis revealed characteristic absorptions of the sulfonic-cellulose succinate half ester; SEM images showed smooth cellulose structures, while the S-CSHE had a compact surface. Effects of S-CSHE on the fluidity of application as the dispersants for the CWS prepared from Chinese Zhundong coal were studied further. The CWS application performance investigations showed that S-CSHE can most effectively reduce CWS viscosity, and perform excellent dispersity and stability. When the dosage of S-CSHE was up to 0.5 wt.%, the maximum coal content of CWS may reach 70 wt.%, and the apparent viscosity of CWS was 487 mPa·s. The CWS prepared using S-CSHE (0.38 wt.%) for Zhundong coal showed the rheological characteristics of shear-thinning, and is consistent with the Herschel–Bulkley model. This work found a new route for utilizing cotton linters cellulose and enlarged the selecting range of the dispersant for CWS. It has a positive significance for efficient and clean utilization of Xinjiang Zhundong coal.

“…It was developed earlier than the 1990s and then got extensive research and application due to its good water solubility and superior dispersing performance. 15,16 Fortunately, we observed an interesting property of SAF that it shows obvious photoluminescence (PL) phenomenon. It is well known that SAF is a polymer containing non-conjugated long linear aliphatic chain with carbonyl and ether bonds.…”

“…Due to higher cost of the synthetic superplasticizer, the usage of it is still not common. Recently less expensive aliphatic ketone based sulfonate acetone formaldehyde condensate (SAF) has been synthesized as a new type of water reducer (Ming et al, 2013;Lei et al, 2012;Pei et al 2004;Zhi et al, 2003).…”

Water soluble sulfonated butanone formaldehyde (SBF) polycondensate superplasticizer was prepared according to a conventional method. UV-Vis, IR and TGA analyses were performed to analyze the target compound. The surface activity was evaluated. It showed a little surface activity with respect to water as the surface tension decreased very little with increasing the concentration of SBF. Thus there results indicate that SBF behaves like a typical polycondensate superplasticizer such as sulfonated acetone formaldehyde (SAF).
