I want to go from Paris to CDG. Since i leave early in the morning, Can i buy my train ticket the night before i leave? Is there a time limit on the ticket?

You can buy your RER B ticket for Paris to CDG the night before (or anytime before). RER tickets don't expire and can be used anytime in the future.
Once you validate the RER ticket in a ticketing gate, you have 120 minutes to complete your trip.
