    Abstract: Dialkyl-hydroxyalkane phosphonates are prepared by reacting a phosphonate and an aldehyde in the presence of a basic catalyst. Dialkyl-hydroxyalkyl phosphonates (I) of formula (1) are produced by reaction of: (A) a phosphonate of formula: (R -O)-PO(OR )-H (2), (B) an aldehyde of formula: R -COH (3), and (C) a basic catalyst, involves (1) mixing (A), (B) and (C), or (2) mixing (A) and (B) or (A) and (C) at 20-60 degrees C, and adding the subsequent component when the mixture reaches 20-60 degrees C, then heating at 61-300 degrees C for 1-30 minutes. R ,R = 1-10C alkyl, 6-13C aryl or 7-14C benzyl, optionally substituted with halogen or hydroxy; R = H, 1-10C alkyl, 6-13C aryl, 7-14C benzyl or a furfuryl Independent claims are also included for: (i) a polyurethane (II) containing (I); and (ii) a process for the production of (II) by reaction of: (D) an organic poly isocyanate, (E) a high mol. wt. compound having, at least, groups containing a hydrogen free to react with isocyanate groups, and (F) a dialkyl-hydroxyalkyl phosphonate (I).
