Abstract
Inventia se refera la un procedeu de obtinere a acidului 1-hidroxi-2-naftoic, prin carbonatarea naftolatului de sodiu, conform caruia în naftolatul de sodiu se introduce bioxid de carbon la presiunea de 10 at, se ridica temperatura la 120 degree C, stabilind o crestere la temperatura de 1 degree C/min, se mareste apoi presiunea de bioxid de carbon la 30 at, se mentine temperatura la 120 degree C timp de 2-3 h, se lasa apoi la racire peste noapte, se purjeaza si se dizolva masa de reactie într-o cantitate de 10 ori în greutate de apa fierbinte, se neutralizeaza cu acid clorhidric concentrat la pH 6,5 se filtreaza fierbinte, iar filtratul se aciduleaza puternic.
