Abstract:
A process for deodorizing a rosin ester composition is disclosed. The process employs an adsorptive bed containing an adsorbent material. The adsorbent material comprises silica adsorbent having an average pore size between 50-200 Å, BET surface area of at least 300 m2/g, pore volume of 1.20 to 3.00 cc/g, and a silanol [Si—OH] level of 0.5 to 5 unit/nm2. The deodorized rosin ester composition has an odor intensity reduction of at least 1 unit on odor intensity scale of Offensive Odor Control Act as compared to the rosin ester feedstock. In embodiment, the deodorizing treatment comprises using multi-staged adsorbent system with an adsorbent column having multiple layers of different adsorbent materials.
