  Acesulfame-K is a widely used sweetener in food and beverage. It is prepared by using the substituted sodium phenoxide or substituted phenol as the starting substance to synthesize the following three intermediates: a substituted phenoxide sulfonylchloride(I), a substituted phenoxide sulfonylamide(II) and an acetoacetamide-N-sulfonyl-substituted phenoxide(III). Particularly, II was prepared by using the liquid or gaseous ammonia to react with I under the action of some catalysts in a reaction column. III was prepared by using II to react with diketene. Acesulfame-K was prepared by ring-closure in III with methanol solution of KOH or K 2 CO 3 .

  阿斯巴甜K是食品和饮料中广泛使用的甜味剂。它是通过使用取代的苯酚钠或取代的苯酚作为起始物质来合成以下三种中间体制备的：取代的苯酚磺酰氯(I)、取代的苯酚磺酰胺(II)和乙酰乙酰胺-N-磺酰基取代苯酚(III)。特别是，II是通过在反应柱中使用液态或气态氨在一些催化剂的作用下与I反应制备的。III是通过使用II与二酮反应制备的。阿斯巴甜K是通过在III中使用氢氧化钾或碳酸钾的甲醇溶液进行环合制备的。

  A heat-storage agent which can store a large quantity of cold heat in the temperature range of 3-5°C, is highly effective in preventing supercooling, and can retain the supercooling-preventing effect even when hydrate solidification/melting is frequently repeated. Also provided are an aqueous solution which enables the formation of a clathrate hydrate serving as a major component of the heat-storage agent, and a process for producing the clathrate hydrate. The aqueous solution contains at least one of tetra-n-butylammonium bromide and tri-n-butyl-n-pentylammonium bromide as a solute and contains tetraisopentylammonium bromide as a supercooling inhibitor, the weight proportion of the tetraisopentylammonium bromide to the tetra-n-butylammonium bromide and/or tri-n-butyl-n-pentylammonium bromide being in a given range. This aqueous solution is cooled to or below a hydrate formation temperature to thereby produce a clathrate hydrate. The heat-storage agent contains this clathrate hydrate as a major component.

  一种蓄热剂，它能在 3-5°C 的温度范围内储存大量冷热，在防止过冷方面非常有效，而且即使在水合物凝固/熔化频繁重复的情况下也能保持防止过冷的效果。此外，还提供了一种可形成作为蓄热剂主要成分的凝块水合物的水溶液，以及一种生产凝块水合物的工艺。该水溶液至少含有四正丁基溴化铵和三正丁基正戊基溴化铵中的一种作为溶质，并含有四异戊基溴化铵作为过冷抑制剂，四异戊基溴化铵与四正丁基溴化铵和/或三正丁基正戊基溴化铵的重量比例在给定范围内。将这种水溶液冷却到或低于水合物形成温度，从而产生一种凝块水合物。蓄热剂的主要成分就是这种水合物。
