    • A continuous method of bleaching an alkylpolyglycoside, substantially free of alcohol, with peroxy compounds, preferably hydrogen peroxide, which is highly efficient to provide an unexpected high degree of color reduction from a dark brown to a light, which product, from an extinction coefficient color respectively of about 10 to about 15 to about 0.025 to about 0.15. The bleaching is carried out at controlled pH and temperature, under pressure preferably in the presence of Mg. The use of a prebleached heel or feed prior to introduction of the unbleached material to be bleached results in a faster approach to equilibrium, steady state, bleaching conditions which results in minimum chemical usage and more rapid production of low color.
    • 使用过氧化合物(优选过氧化氢)漂白基本上不含醇的烷基多糖苷的连续方法,该方法高效地提供从暗棕色到光的意想不到的高度的颜色还原,该消光系数颜色 分别为约10至约15至约0.025至约0.15。 在控制的pH和温度下,优选在Mg存在下,在压力下进行漂白。 在引入待漂白的未漂白材料之前使用预先漂白的脚后跟或饲料导致更快的平衡,稳定状态,漂白条件的方法,这导致最少的化学使用和更快的低颜色生产。

    • Processes for purifying compounds are disclosed which include reacting (i) a mixture of at least one tocopherol compound or sterol compound, and an alcohol having from about 10 to 30 carbons with (i) one or more boron-containing compounds to form a second mixture of orthoborate esters, wherein the mole ratio of tocopherol, sterol and alcohol to boron is at least about 2.5:1; heating the second mixture to form a residue containing the orthoborate esters; contacting the residue with a compound capable of solvolyzing the orthoborate esters to form a third mixture including the boron-containing compound(s), the alcohol and the tocopherol and/or sterol compound(s); and recovering the tocopherol and/or sterol compound(s). Another process for purifying such compounds includes an activated carbon treatment, which may alternatively follow the other process steps; formation of borate esters; heating to remove low boiling point components; formation of a residue comprising the borate esters; contacting the residue with a compound capable of solvolyzing the borate esters; and separation of the remaining components. Compositions including mixtures of alkyl/tocopherol/sterol orthoborate esters are also disclosed.
    • 公开了用于纯化化合物的方法,其包括使(i)至少一种生育酚化合物或固醇化合物的混合物与具有约10至30个碳的醇与(i)一种或多种含硼化合物反应以形成第二混合物 的正硼酸酯,其中生育酚,固醇和醇与硼的摩尔比为至少约2.5:1; 加热第二混合物以形成含有原硼酸酯的残余物; 使残余物与能够使原硼酸酯溶剂化的化合物接触以形成包含含硼化合物,醇和生育酚和/或固醇化合物的第三混合物; 并回收生育酚和/或固醇化合物。 净化这些化合物的另一种方法包括活性炭处理,其可以替代地遵循其它工艺步骤; 形成硼酸酯; 加热去除低沸点组分; 形成含有硼酸酯的残渣; 使残余物与能够溶解硼酸酯的化合物接触; 并分离其余组分。 还公开了包括烷基/生育酚/正硼酸甾醇酯的混合物的组合物。
