Abstract
本发明涉及使用固体氧化剂在混合下,尤其是在鸷揑和机或挤出机中于80-160℃的温度下漂白几乎无水和无脂肪醇的烷基聚苷的方法。
Description
本发明涉及用固体氧化剂在80-160℃的温度下混合漂白几乎无水和无脂肪醇的烷基聚苷的方法。混合是在例如捏和机或挤机中进行的。
烷基聚苷是由天然原料制备的并且是无毒的和易分解的表面活性物质。因此,它们被用作洗涤剂、净化剂、乳化剂和分散剂。但是,只有当烷基具有至少8个碳原子时,它才具有所希望的表面活性特性。本发明的烷基聚苷符合下式:
R′-O-Zn′式中R′代表非支链或支链,饱和或未饱和的具有8-18个碳原子的脂肪族烷基或其混合物,Zn代表具有n=1.1-3个己糖或戊糖单元或其混合物的多糖基团。
优选地,烷基聚苷中烷基具有12-16个碳原子以及多糖基团的n=1.1-2。特别优选地,烷基聚苷中多糖基团的n=1.1-1.5,更特别优选地n=1.2-1.4。作为多糖基团,优选的是烷基葡聚糖基团。具有长链烷基的烷基聚苷一般是通过一阶段或多阶段合成制备的。DE-A-4101252中描述了一阶段的制备方法。
EP-A-0306652中介绍了两阶段制备方法的例子,其中首先通过正丁醇的苷化制备正丁基苷,然后通过长链醇的再苷化制备所希望的长链烷基聚苷。
反应结束后,有烷基聚苷溶解在长链醇中。如果要获得在水中完全溶解的产物,接着必须分离这些醇。
烷基聚苷是一类产物,在对其美观有较高的要求时,必须进行漂白反应,由此得到充分透明的产物。这种漂白是在采用过氧化氢的情况下在烷基聚苷的水溶液中进行的。不利的是,采用该方法时降低了时空产率,这主要是为了完全分解剩余的过氧化物,还必须将烷基聚苷水溶液在升高的温度下保持较长的时间。因而会有损产物,从而产生深色以及具有令人厌恶气味的部分分解物。此外,还存在着不再可控制的泡沫形成的危险。
WO91/19723描述了一种烷基聚苷的漂白方法,其中将实际上无脂肪醇和无水物质在50-150℃的温度下与含水的过氧化氢和例如作为碱的氢氧化钠溶液揑制。按这种方法,不再出现上述在水溶液中漂白烷基聚苷的不利因素。不利的是按这种方法不可能在值得重视的高于100℃温度下进行漂白。而无脂肪醇或无水的产物常常是在高于100℃的温度下才可揑制。此外,在氢氧化钠溶液的加入上会有困难。在漂白反应时必须通过添加碱来补偿某些酸作用。只有花费大量的费用才能调节氢氧化钠溶液的添加量,这是因为在熔融物中不能直接测定PH值。手工定量总是带来用量过多或过少的危险,从而迅速降低漂白效果。
本发明的任务是发现一种方法,该方法允许在熔融物中进行氧化漂白,而不存在所述的过氧化氢和氢氧化钠溶液的添加问题。
目前已经发现,如果用固态漂白剂如过碳酸钠或过硼酸钠代替过氧化氢水溶液,那么可在高于100℃的温度下获得极好的漂白效果。
因此,本发明的主题是提供一种漂白几乎无水和无脂肪醇的烷基聚苷的方法,其特征在于加入固体氧化剂并且在混合下于80-160℃的温度下进行反应。
对此,优选地温度为90-150℃,特别优选地温度为100-140℃。作为烷基聚苷,优选使用烷基葡聚糖苷。
采用例如挤出机或揑和机在粘稠的APG(温度:80-160℃)中加入物质没有困难,从而可获得均匀的产品。在漂白期间无须添加碱,这是因为在使用这种漂白剂时,PH值未变小。所得到的产品是很透明的并且是无味的。在漂白之前加入少量的水可改进漂白效果。水的添加量可为0-10%,但优选地为0-5%。漂白时的脂肪醇含量为0-10%,优选地为0-5%,特别优选地为0-2.5%。
