Isopropylamine & Diisopropylamine azeotropes?

I've U'd TFSE, but only got one result on azeotropes (mentioning only Acetone as a possible candidate).

I've got about 500mls of freshly distilled, fairly wet (80%-90%) IprNH2 that I still need to dry with NaOH and frac. distill (unless anyone has any other slick ideas), for alkylation to DIPA with IprBr, and finally DIPEA (Hunig's base) with EtBr.

Are there any azeotropes that Isopropylamine and/or Diisopropylamine form with any of the aforementioned reactants and products? Any that you know of in general with these that are useful to know?
