    摘要： THERE IS PROVIDED A PROCESS FOR IMPROVING THE COLOR OF A TALL OIL ROSIN PENTAERYTHRITOL ESTER BY PRETREATING A TALL OIL ROSIN WITH FROM 0.5% TO 2.5% PARAFORMALDEHYDE AT A TEMPERATURE OF FROM 140*C. TO 180*C. FOR FROM ONE TO THREE HOURS, DISTILLING THE SAME, AND THEREAFTER EFFECTING THE ESTERIFICATION OF THE SO-TREATED TALL OIL ROSIN WITH PENTAERYTHRITOL AT A TEMPERATURE RANGING FROM ABOUT 250* C. TO 300*C.

    摘要： MIXTURES OF UNSATURATED HIGHER FATTY ACIDS CONSISTING PREDOMINANTLY OF OLEIC AND NON-CONJUGATED LINOLEIC ACIDS ARE POLYMERIZED IN TWO STAGES. IN THE FIRST STAGE, THE MIXTURE IS HEATED AT 180*C. TO 260*C. IN THE PRESENCE OF A SMALL AMOUNT OF WATER AND AN ALKALINE EARTH METAL SALT MODIFIED MINERAL CLAY FOR ABOUT 2-5 HOURS. RESIDUAL UNPOLYMERIZED ACIDS, PRINCIPALLY UNMODIFIED OCTADECENOIC ACIDS, ARE SEPARATED FROM THE REACTION PRODUCT AND MAY BE DIMERIZED IN A SECOND STAGE BY HEATING AT 220*C.260*C. FOR ABOUT 2-5 HOURS IN THE PRESENCE OF A SMALL AMOUNT OF WATER AND OF AN ACID-ACTIVATED MINERAL CLAY, WHICH IS PREFERABLY A MONTMORILLONITE CLAY.
