    Abstract: A process is described for reducing the discoloration of PO3G. The discolored polymer is contacted with adsorbent and separated therefrom, for instance, by filtration. The treated polytrimethylene, preferably, has an APHA color of less than about 50 and a molecular weight of about 250 to about 5000.

    Abstract: Processes for reducing color in PO3G are provided. The processes include contacting PO3G with an adsorbent and then separating the PO3G from the adsorbent by, for example, filtration. The process provides PO3G having an APHA color preferably less than about 50. The processes are desirably used for polymers having a molecular weight of about 250 to about 5000.

    Abstract: Processes for reducing color in PO3G are provided. The processes include contacting PO3G with an activated carbon and then separating the PO3G from the activated carbon by, for example, filtration. The process provides PO3G having an APHA color less than that before contact with the absorbent. The processes are desirably used for polymers having a molecular weight of about 250 to about 5000.

    Abstract: A catalyst composition is disclosed. The composition comprises a titanium compound, a phosphorus compound, an amine, a solvent and optionally a cocatalyst in which the phosphorus compound has a formula selected from the group consisting of (R.sup.1 O).sub.x (PO)(OH).sub.3-x, (R.sup.1 O).sub.y (P.sub.2 O.sub.3)(OH).sub.4-y, and combinations thereof; the amine is a tertiary amine; each R.sup.1 is independently a linear or branched alkyl radical containing from 1 to about 20 carbon atoms per radical; x is 1 or 2; and y is 1, 2, or 3; and the cocatalyst can be a cobalt/aluminum catalyst, an antimony compound, or combinations thereof. Also disclosed is a process for producing the composition. The process comprises combining a titanium compound, a phosphorus compound, a solvent, an amine, a solvent, and optionally a cocatalyst. The phosphorus compound, amie, and solvent are the same as those disclosed above. Further disclosed is a process for using the composition which comprises contacting a carbonyl compound, in the presence of the composition, with an alcohol under a condition suitable for esterification, transesterification, polymerization, or combinations thereof.
