Abstract
"PROCESSO DE MELHORAMENTO PARA OBTENçãO DE UM POLIOL OLEOQUìMICO, OBTENDO-SE POLIURETANO COMO FASE FINAL". Compreendendo a reação química entre óleos naturais, vegetais e/ou marinhos, por transesterificação com compostos poliidroxilados (glicerina, trimetilol propano, pentaeritritol, sorbitol aminoalcoóis) isolados ou em conjunto com glicoóis (etilenoglicol, propilénoglicol, dietilenoglicol, neopentiloglicol), polimerizados a altas temperaturas (200<198> - 240<198> centígrados) para posteriormente serem submetidos à reação com poliisocianatos (aromáticos e/ou alifáticos) e obterem-se poliuretanos como fase final."PROCESS OF IMPROVEMENT TO OBTAIN AN OLEOCHEMICAL POLYOL, OBTAINING POLYURETHANE AS A FINAL PHASE". Understanding the chemical reaction between natural, vegetable and / or marine oils, by transesterification with polyhydroxylated compounds (glycerin, trimethylol propane, pentaerythritol, sorbitol aminoalcohols) isolated or together with glycools (ethylene glycol, propylene glycol, diethylene glycol, neopentyl glycol at high temperatures), polymerized (200 <198> - 240 <198> centigrade) to be subsequently subjected to reaction with polyisocyanates (aromatic and / or aliphatic) and polyurethanes are obtained as the final phase.
