Abstract
Inventia se refera la un procedeu de obtinere a unor Naril-3-hidroxi-2-naftalincarboxamide de înalta puritate, cu formula generala : (VEZI FORMULA îN DESC.) în care A r reprezinta un radical fenil sau fenil substituit cu grupe alchil inferior sau alchil inferior, prin condensarea sarii de sodiu a acidului 3-hidroxi -2-naftoic cu amide aromatice, în prezenta de triclorura de fosfor în mediu de toluen anhidru, la temperatura de 70....109 degree C, si filtrarea masei de reactie în care filtrea masei de reactie în care filtreaza masei condensate se realizeaza la o temperatura minim 50 degree C în mediu acid fara neutralizarea acesteia, iar pasta obtinuta cu un continut de solvent de 20....40% se suspenda în apa, cu sau fara adaos de agent tensioactiv se agita pana la dispersarea completa iar apoi se filtreaza suspensia omogena 50....90 degree C, prelucrand apoi în mod cunoscut.
