| abstract | PREPARATION PROCEDURES FOR ORGANOPHOSPHERATED ADDITIVES OBTAINED FROM CHEMICAL MODIFICATION OF 3-n-PENTADECILPHENOL FOR APPLICATION IN INDUSTRIAL SECTORS. The invention consists in the process of preparing eight organophosphate additives obtained by chemical modification of Cashew Nut Shell (distilled or technical) after the hydrogenation process. The preparations take place in a reaction vessel (1) coupled to a thermostat (2) and reflux (3), whose reaction vessel (1) in addition to 3-n-pentadecylphenol, sodium hydroxide (4), chloroform (5) is added. ) chlorophosphate binder (6) or chlorophosphite binder (7). The temperature is kept constant (40 - 60 ° C) and reaction times are variable. Subsequently, the reaction media are poured into separation funnels (8) for the development of extraction processes via sulfuric acid and water solution (9). The products are then dried with anhydrous sodium sulfate (10) and rotary evaporated to remove solvent (11). Products (12) based on 3-n-pentadecylphenol are purified chromatographically (13) using silica gel 60 and hexane: dichloromethane as the eluents as adsorbents. Additives involve simple steps, generate biomass derivatives and are handled by environmentally friendly processes. The phosphoration processes have high selectivity in the aromatic ring hydroxyl, a fact that distinguishes the additives by their high degree of purity. |
