The present invention relates to phenol-free phosphites and preparation thereof. The phenol-free phosphites are obtained by reacting biphenol, and phosphorous derivatives with higher aliphatic alcohol via condensation and trans-esterification. The phenol-free phosphites of the present invention can be used as a heat stabilizer for resin so as to enhance the heat resistance of the resin during processing at high temperatures.
