摘要： The invention relates to a method of producing xylitol and erythritol from arabinoxylan-containing material. According to the invention, the arabinoxylan-containing material is hydrolyzed and xylose and arabinose are separated from the obtained hydrolysate, whereafter the xylose is reduced to xylitol, and the xylitol is recovered, and the arabinose is subjected to alkaline oxidation to obtain erythronic acid which is reduced to erythritol, and the erythritol is recovered.
摘要翻译：本发明涉及含有阿拉伯木聚糖的材料生产木糖醇和赤藓糖醇的方法。根据本发明，将含阿拉伯木聚糖的材料水解，从得到的水解产物中分离出木糖和阿拉伯糖，然后将木糖还原成木糖醇，并回收木糖醇，并将阿拉伯糖进行碱性氧化，得到红霉素还原成赤藓糖醇，回收赤藓糖醇。

摘要： A method for controlling the alkaline delignification processes, especially the sulphate process of wood or other materials containing cellulose by the interdepending concentrations of the hydroxymonocarboxylic acids which are formed in the process and dissolved into the waste liquor. According to the method a sufficient number of representative waste liquor samples are taken during the process and the acids present in the samples are analyzed by gas chromatography. Thus, the required time interval for achieving the desired cooking stage can be determined by using the interdepending ratios of the concentrations of certain acids.
摘要翻译：一种用于控制碱脱木素过程的方法，特别是通过在该方法中形成并溶解到废液中的相互依赖的羟基单羧酸浓度的木材或其它含有纤维素的材料的硫酸盐方法。根据该方法，在该过程中取出足够数量的代表性废液样品，并通过气相色谱分析样品中存在的酸。因此，可以通过使用某些酸的浓度的相互比例的比例来确定用于实现所需烹饪阶段所需的时间间隔。

摘要： A procedure for determining the composition of a wood chip mix dispensed in alkaline delignifying processes, particularly in sulphate and soda/anthraquinone cooking, with the aid of the monomeric compounds produced in connection with the cooking and dissolved in the waste liquor. As taught by the procedure, a cooking liquor sample is taken in the cooking process, this sample being chromatographically analyzed. On the basis of the content proportions of certain compounds analyzed by substance groups, the composition of the dispensed wood chip mix is determined, and at the same time information is gained for optimating the conditions applied in the cooking process.
摘要翻译：借助于与烹饪相结合并溶解在废液中产生的单体化合物，确定分配在碱性脱木素方法中的木屑混合物的组成的方法，特别是在硫酸盐和苏打/蒽醌烹饪中。如本程序所述，在烹饪过程中摄取烹调液样品，对该样品进行色谱分析。根据由物质组分析的某些化合物的含量比例，确定分配的木片混合物的组成，同时获得用于优化烹饪过程中应用条件的信息。
