    摘要： The present invention relates to a process for making the esters of 2,5-furandicarboxylic acid, and particularly the dimethyl, diethyl or dipropyl esters of FDCA for use as monomers in the production of polyesters and other types of polymers with biobased content, comprising: reacting an aqueous feed comprising glucaric acid with a high boiling first alcohol in the presence of an acid catalyst and with removing water during the reaction, to form a first product mixture comprising a first ester of FDCA and the high boiling first alcohol; removing unreacted high boiling first alcohol from the first product mixture; combining the first ester of FDCA and the high boiling first alcohol with a lower boiling second alcohol selected from the group consisting of methanol, ethanol, isopropanol and n-propanol; transesterifying the first ester with the lower boiling second alcohol to form a second product mixture comprising a second ester of FDCA with the lower boiling second alcohol; and recovering the second ester of FDCA with the lower boiling second alcohol.

    摘要： An inorganic polymer electret in a colloidal state, for example silica, is generated by utilizing a magnetic field gradient through which the materials are passed. Referring to Figure 7, materials (5), aqueous sodium silicate and NaOH plus tripotassium citrate, are pumped from container (3) by pump (1) in conduit (2) through conduit (6) into conduit (7) out through holes (8), into conduit (13) out through holes (9), into conduit (14) out through holes (10), whereby the material reverses direction twice, and then enters into conduit (15) and chamber (11) in order, and finally is carried back to container (3) through conduit (4). Magnetic booster units (A), (B) and (C) shown in Figure 8 are added to build the electrostatic charge on the colloid faster.
