Abstract:
A new process is studied for the synthesis o f alcohol ethoxy late phosphate prepared by esterify ing alco hol et hox ylate ( AEO3) wit h phosphorus pentoxide in the presence of w ater and hydrolyzing w ith steam. The o ptimum conditions for the esterfying is that the molar ratio of the reactants, or AEO3：H2O：P2O5= 2：1：1, temper ature is 70℃ and time is 2. 5 h. The pr oduct of the esterifying is hydrolyzed by steam bubbling ( 30 kg / h) at 95 ℃for 50~ 60 min. The esterificat ion rate is above 93%, w hile the monophosphat e( MAEP) content is above 89% and the product is odorless and colorless.
