Is "propanol" a correct name in IUPAC nomenclature?
The last IUPAC nomenclature recommendations were published in 1993. The current draft documents (release date uncertain) are far more lenient in their acceptance of semi-systematic naming of molecules. Please make sure you understand the differences between the Preferred IUPAC Name (PIN), the retained name, and trivial name. 

Propanol is not be the preferred IUPAC name, but significantly, neither is it listed in the tables of Trivial and semisystematic names retained for naming organic compounds. It is, however, a widely accepted name for this chemical, and you are far more likely to encounter propanol in industry than propan-1-ol. Nobody uses propan-1-ol in the real world, even if it is the preferred IUPAC systematic name.
