    摘要: A high pressure extraction apparatus and extracting method therefor are adapted to maintain a medium at the supercritical state to extract substance-to-be-extracted. The apparatus includes an extraction tank, a piston and a control unit. The control unit controls the piston to reciprocate in the extraction tank as well as controls the pressure of the extract space of the tank, feeding of the substance, discharge of extract, and discharge of leftover. Accordingly, the apparatus performs a continuous supercritical extraction.

    摘要: The present invention provides a novel poly(1,3-propylene terephthalate), which is prepared from reacting terephthalic acid and 1,3-propanediol in the presence of an effective catalytic amount of ethylene glycol titanate to undergo esterification to form a monomer; and polymerizing the monomer in the presence of an effective catalytic amount of antimony acetate to obtain poly(1,3-propylene terephthalate). The obtained poly(1,3-propylene terephthalate) (PPT) has an intrinsic viscosity (IV) of 0.65-0.91 dl/g, acid number (--COOH amount) of less than 40 meq/kg, and L*>60. Without adding a pigment, the yellowness b* of PPT is below 9, even below 5. The yellowness b* of PPT even reaches below 3 when a pigment is incorporated.
