Organofunctionalization of Natural Palygorskite with Ethylene Sulfide in the Absence of a Solvent

Abstract:

The search for functional materials has increased daily in order to improve their functionality while maintaining a low cost. Among the materials of considerable interest are clays and within them is a particular clay known as palygorskite, which contains a hydrated silicate of aluminum and magnesium with a fibrous morphology. This work achieved the organofunctionalization of palygorskite with ethylene sulfide in the absence of a solvent. Through the elemental analysis of sulphur, the incorporation of 9.73 ± 0.36 mmol g^-1 was identified. A significant decrease in the crystallographic planes (110) and (040) was identified in the XRD. The FTIR showed vibrations of stretching and deformation of the methylene groups in the region below 3000 and in 1421 cm^-1, respectively. The deformation related to the C-S group in the region of 700 and 600 cm^-1, and the surface area (BET) showed a significant reduction from 113 to 7 m² g^-1. Additionally, the SEM presented a loss of fibrous character.
