  Polyol is recovered from polyurethane based polyurethane foam by a process which includes first dissolving the foam in a saturated alcohol, preferably diethylene glycol, having a boiling point between about 225°C and 280°C at a temperature between about 185°C and 220°C under a non-oxidizing atmosphere. The solution is reacted with water in the presence of an alkali hydroxide catalyst, preferably sodium hydroxide, under a non-oxiding atmosphere, such as nitrogen. This may be done by refluxing the solution at a temperature between 175°C and 220°C until all the carbamates produced during dissolution have been hydrolyzed to amines and alcohol. Water remaining in solution after hydrolysis is removed. A high boiling alkane is used to extract the polyol from the solution still under a non-oxidizing atmosphere and then the extracted polyol is subjected to vacuum purification at a temperature of less than about 230°C. Substantially pure polyol is recovered which can be used to make new foam.

  从聚氨酯基聚氨酯泡沫中回收多元醇的工艺包括首先将泡沫溶解在饱和醇（最好是二甘醇）中，饱和醇的沸点在约 225°C 至 280°C 之间，温度在约 185°C 至 220°C 之间，在非氧化气氛下进行。在非氧化气氛（如氮气）下，在碱氢氧化物催化剂（最好是氢氧化钠）存在下，溶液与水反应。可将溶液在 175°C 至 220°C 的温度下回流，直到溶解过程中产生的氨基甲酸酯全部水解为胺和醇。水解后残留在溶液中的水被除去。使用高沸点烷烃在非氧化气氛下从溶液中提取多元醇，然后在低于约 230°C 的温度下对提取的多元醇进行真空提纯。回收的多元醇纯度很高，可用于制造新的泡沫塑料。

  The use of tetrahydrobenzoxazines I where R1 is a hydrocarbyl radical and R2, R3, R4 and R5 are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals, and where R2 to R5 may also form a second and a third tetrahydrooxazine ring, with the proviso that at least one of the substituents has from 4 to 3000 carbon atoms and the remaining substituents, when they are hydrocarbyl radicals, each have from 1 to 20 carbon atoms, as stabilizers for stabilizing inanimate organic material, especially turbine fuels, against the action of light, oxygen and heat.

  使用四氢苯并恶嗪 I 其中 R1 是烃基，R2、R3、R4 和 R5 各自独立地为氢原子、羟基或烃基，R2 至 R5 还可形成第二个和第三个四氢噁嗪环，但至少有一个取代基具有 4 至 3000 个碳原子，其余取代基（当它们是烃基时）各自具有 1 至 20 个碳原子，可用作稳定剂，稳定无生命的有机材料，特别是涡轮燃料，使其免受光、氧和热的作用。
