Abstract
Conform inventie, procedeul de sinteza a acizilor mono si dialchil-fosforici prin C10 si a 2-etilhexanolului consta în aceea ca peste oxiclorura de fosfor se adauga prima parte de 2-etilhexanol în timp de 1 h si temperatura amestecului se ridica la 65 degree C în timp de 1.....1,5 h astfel ca HCl folosindu-se gaz inert sau aer apoi amestecul se încalzeste la 65.....75 degree C pentru hidroliza clorurilor acizilor mono si di(2-etilhexil)-fosforici cu apa demineralizata în timp de 3 h la 35.....40 degree C dupa care amestecul de reactie se mentine sub agitare 1....2 h la 40 degree C apoi faza organica se separa de solutia apoasa eventual amestecul de reactie se neutralizeaza cu hidroxizi sau carbonati de metale alcaline.
