A procedure to construct the sequences of quantum canonical transformations for integrating Schrödinger equations was developed. A factorization technique analogous to the method of integration factor in classical integration was also developed. Nine nontrivial models including the centripetal barrier potential, Kratzer's molecular potential, Morse potential, Pöschi-Teller potential and the Hulthen potential were integrated for the purpose.
