Home, and digging through the shelf now...
In 1931's
Spacehounds of IPC by EE Doc Smith, the chapter "A Frigid Civilization" details a visit to the civilization on Titan, not to mention their "crystal city" (primary building material: ice) They meet the spacefaring Titanians somewhere near Ganymede in the previous chapter... but Titan is a bleak white and black world with an atmosphere of mostly oxygen...

For thousands and thousands of years there must have gone on the gradual adaption of bloodstream and tissue to more and more volatile liquids, and to lower and still lower temperatures. ...
What do you make of this chemical solution blood of their's, Steve? asked Nadia, watching the placidly floating Titanian captain.
... I gathered that it is something like polyhydric alcohol and something like a substituted hydrocarbon, and yet different from either in that it contains fluorin in loose combination.
... remember that the vital fluid of life here, animal and vegetable, corresponding to out water, is probably more flammable than gasoline.
But I was wrong, the Titanians were the nice guys, and I was totally confusing them with the Chlorans from a different series.
Man, I love these books, they're such a trip.
