摘要： A continuous process for making alkyl aldosides from polysaccharides and more particularly mixed alkyl glycosides from starch by direct alcoholysis. A polysaccharide, such as starch, is slurried in an alcohol and passed through a heated, confined zone under pressure in the presence of an acid catalyst to form a mixed alkyl aldoside. The alcohols which may be used include methanol, ethanol, propanol and butanol, their isomers and mixtures thereof. Higher alkyl glycosides are surfactants and, in some instances, it is advantageous to use higher alcohols, such as decyl and dodecyl alcohols, to obtain particular surfactant properties in the resulting alkyl glycosides. Mixed alkyl glycosides are useful in detergent applications, and as backbone polymers in polyurethane foams.

摘要： Glycoside-containing polyester products having improved color characteristics are provided by a polyester preparation process in which a polyol reactant containing at least a minor proportion of a glycoside reactant is reacted with a lower alkyl ester of a polybasic acid. The color characteristics of such products are notably improved relative to that which is obtained when said reaction is instead conducted using the corresponding polybasic acid or anhydride in place of the indicated lower alkyl ester thereof.The color improvement benefits of the present invention are particularly pronounced and dramatic when the polybasic acid component of the desired polyester product comprises an aromatic polybasic acid and when a lower alkyl ester of said aromatic polybasic acid is employed in the reaction in place of the aromatic acid itself.

摘要： The present invention relates to the preparation of aldoside mixtures, recovering at least a portion of one aldoside component therefrom and reusing the remaining portion of the aldoside mixture to prepare additional aldoside. The aldoside mixture may be prepared by slurrying the carbohydrate in alcohol and passing the slurry through a continuous reactor at an elevated temperature under fluid pressure in the presence of an acid catalyst. The resultant aldoside mixture may then be partitioned into a mother liquor portion and an aldoside portion by selectively recovering at least a portion of one aldoside from the crude aldoside mixture with the remaining mother liquor being recycled.Crude glycoside mixtures prepared from starch and methanol slurries are suitable substrates for selectively recovering methyl-alpha-D-glucopyranoside. The methyl-alpha-D-glucopyranoside may be easily crystallized and recovered from the glycoside mixture because of its lower solubility in methanol. The resultant mother liquor (rich in the remaining components of the glycoside mixture) in combination with freshly added starch and methanol provides a reaction medium which optimizes methyl-alpha-D-glucopyranoside production.
摘要翻译： 本发明涉及醛糖苷混合物的制备，从其中回收至少一部分一种醛苷成分，并重新使用其余部分的醛糖苷混合物制备另外的醛糖苷。 醛糖苷混合物可以通过将碳水化合物在醇中制浆并使浆液在升高的温度下在酸性催化剂的存在下在流体压力下通过连续反应器来制备。 然后通过选择性地从粗醛苷混合物中回收至少一部分来自粗制醛苷混合物的一种醛糖苷，将所得的醛糖苷混合物分配成母液部分和醛糖苷部分，剩余的母液被再循环。 由淀粉和甲醇浆液制备的粗糖苷混合物是选择性回收甲基-α-D-吡喃葡萄糖苷的合适底物。 由于甲基-α-D-吡喃葡萄糖苷在甲醇中的溶解度较低，甲基-α-D-吡喃葡萄糖苷可以容易地结晶并从糖苷混合物中回收。 所得到的母液（富含剩余组分的糖苷混合物）与新鲜淀粉和甲醇的组合提供了优化甲基-α-D-吡喃葡萄糖苷生产的反应介质。

摘要： An improved method for thinning starch in the granular state employing hydrogen peroxide and metal ion catalysts in an aqueous suspension, free of buffer additions. The thinning action proceeds in acid pH to the desired viscosity level, and is stopped by the addition of sodium metabisulfite, or other reducing agent to remove residual hydrogen peroxide. The aqueous suspension is then neutralized, and the usual purifying and drying steps are effected on the granular product.
