PROCESS OF CONFECTION OF CARTRIDGE TIPO OBTAINED [C]18 WAY THERMAL TREATMENT FOR USE IN EXTRACTION IN SOLI

NOVELTY – The solid-phase extraction-type C18 cartridge manufacture has substitution of the organo chlorosilane reagent by PMODS (poly(methyloctadecyl siloxane)polymer), a source of C18 aliphatic chains. The chemical reaction is substituted by physical sorption of the PMODS on silica, followed by thermal immobilization of the PMODS and elimination. USE – In Chemical engineering.

Main Application Field

A97 (Miscellaneous goods not specified elsewhere – including papermaking, gramophone records, detergents, food and oil well applications.); A26 (Other condensation polymers including silicone polymers and polyimides (mineral silicates and similar materials would not usually appear in Section A).); J01 (Separation – including evaporation, crystallisation, solvent extraction, chromatography, dialysis, osmosis including drying gases and/or vapours, and separation of solids from gases, liquids and other solids. Isotope separation, filter materials (including molecular sieves for separation), and centrifuges (except where used for analysis) (B01D, B03, B04, B07B).)
