Sodium-aluminium silicates of a high degree of dispersion were obtained. Studies on the surface modi cation of sodium-aluminium silicates using silane coupling agents are described. The best modi ers, which induced a change of the silicate surface from a hydrophilic to a hydrophobic one, were selected. Physicochemical analyses of the obtained silicates were performed. The methods of evaluating the degree of surface modi cation of the silicate are presented. Attempts were made to employ the unmodi ed and modi ed sodium-aluminium silicates as llers in polyurethane elastomers. The introduction of sodium-aluminium silicate into urethane elastomer induced increases in composite parameters such as tensile strength, relative elongation, and hardness. The most pronounced reinforcing effects were observed with urethane elastomers lled with sodium-aluminium silicate modi ed with an aminosilane (A-1120).

To understand fumaric acid sludge (FAS) systematically and comprehensively and find out how to utilize it, we conducted a series of characterization analyses on FAS. Fourier transform infrared (FT-IR) Spectra shows that the main component of FAS is fumaric acids and also contains a small amount of silicate. The nuclear magnetic resonance hydrogen (1H-NMR) spectrum also shows that fumaric acid accounted for a large proportion of FAS. The X-ray diffraction (XRD) shows that the main phase in FAS is fumaric acid, and there is also a small amount of Kaliophilite. After gas chromatography and mass spectrometry (GC-MS) and pyrolysis gas chromatography and mass spectrometry (Py-GC-MS) analysis, it indicates that the possible volatiles and pyrolysis products in FAS are fumaric acid, maleic acid, maleic anhydride, phthalic acid, etc. In the test of Liquid chromatography and mass spectrometry (LC-MS), we determined the contents of phthalic acid, fumaric acid, and maleic acid in FAS. The detailed mass content of each component in FAS is as follows: phthalic acid is about 0.10–0.15%; maleic anhydride is about 0.40–0.80%; maleic acid is about 18.40–19.0%; fumaric acid is about 55.00–56.90%; succinic anhydride is about 0.06–0.08%; acrylic acid is about 0.06–0.08%; malic acid is about 0.90–1.00%; acetic acid is about 0.10–0.20%; silicate is about 0.25–0.30%; phthalic anhydride is about 0.20–0.30%; water is about 24.30–24.80%. The filtrate loss reducer (PAAF) used in oilwell drilling fluids synthesized by FAS not only has excellent temperature and complex saline resistance, the API filtration loss (FL) was only 13.2 mL/30 min in the complex saline based mud, but is also cost-effective.

“…In the literature, there have been many studies on the synthesis of magnesium silicates 47,[49][50][51][52][53][54][55] . Methods to control the physicochemical properties and morphology of magnesium silicates have also been examined, including the effects of surface modification 16,[56][57][58][59][60][61][62] www.nature.com/scientificreports/ surfactants 16 , and sodium hydroxide 13 , as well as the effects of pH on synthesis 49 and adsorption capacity 63 . Compared with the polycrystalline structure of natural magnesium silicate minerals, synthetic magnesium silicates commercially available are often amorphous and porous, potentially resulting in more significant dissociation in a liquid dispersion system.…”

Magnesium silicate is an inorganic compound used as an ingredient in product formulations for many different purposes. Since its compatibility with other components is critical for product quality and stability, it is essential to characterize the integrity of magnesium silicate in different solutions used for formulations. In this paper, we have determined the magnitude of dissociation of synthetic magnesium silicate in solution with positively charged, neutral, and negatively charged compounds using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and Liquid Chromatography-High Resolution Mass Spectrometry (LC-HRMS). The EDS results were verified through Monte Carlo simulations of electron-sample interactions. The compounds chosen for this study were positively charged cetylpyridinium chloride (CPC), neutral lauryl glucoside, and negatively charged sodium cocoyl glutamate and sodium cocoyl glycinate since these are common compounds used in personal care and oral care formulations. Negatively charged compounds significantly impacted magnesium silicate dissociation, resulting in physio-chemical separation between magnesium and silicate ions. In contrast, the positively charged compound had a minor effect on dissociation due to ion competition, and the neutral compound did not have such an impact on magnesium silicate dissociation. Further, when the magnesium ions are dissociated from the synthetic magnesium silicate, the morphology is changed accordingly, and the structural integrity of the synthetic magnesium silicate is damaged. The results provide scientific confidence and guidance for product development using synthetic magnesium silicate.
