摘要： An artificial sweetener composition contains sucralose and optionally a bulking agent such as maltodextrin. The composition is in the form of granules having a size between 30 and 2000 µm and containing between 0.5 and 1.5 wt% moisture. Any process can be used for making the compositions, with one especially applicable one involving pressing a powdered feed containing the raw materials between rolls to form a densified mass. The densified mass is then broken down in size and optionally fractionated by particle size.

摘要： This invention relates to processes for purifying sucralose by the use of an initial non-crystallization purification procedure followed by three or more sequential crystallization steps and recycle of the mother liquor remaining from each crystallization step to the feed of another crystallization or purification step. This invention also relates to sucralose compositions as well as compositions comprising the sucralose compositions of the present invention. These compositions may be highly pure and have a superior taste profile.

摘要： Sugars and partly protected sugar derivatives are chlorinated by reaction of unprotected hydroxyl groups with thionyl chloride to form a persulphite followed by decomposition of the sulphite groups to form chlorosulphites, displacement of the chlorosulphite groups and insertion of chlorine atoms at one or more positions, characterised in that formation and displacement of the chlorosulphite groups and insertion of chlorine atoms is effected by reaction with thionyl chloride in an inert solvent in the presence of a quaternary salt of the general formula:
N⁺R¹R²R³R⁴ Cl⁻ (I)
wherein R¹, R² and R³, which may be the same or different, each represent a lower alkyl group, and R⁴ represents a hydrocarbon group with at least seven carbon atoms; and, when the sugar or partly protected sugar derivative has more than three unprotected hydroxyl groups, the process comprises the following stages:
(a) reaction of the sugar or partly protected sugar derivative with thionyl chloride in the presence of pyridine to form a persulphite; (b) isolation of the polysulphite to remove free pyridine; and (c) reaction of the isolated polysulphite with thionyl chloride in an inert solvent or suspension medium in the presence of a quaternary salt of the general formula (I).摘要翻译： 糖和部分保护的糖衍生物通过未保护的羟基与亚硫酰氯反应形成亚硫酸氢盐，接着分解亚硫酸盐基团以形成氯亚硫酸盐，置换氯亚硫酸盐基团和在一个或多个位置插入氯原子，其特征在于 在通式为：N + R 1 R 2 R 3 R 4 Cl - （Ⅰ）的季盐存在下，在惰性溶剂中与亚硫酰氯反应，氯亚硫酸盐基团的形成和置换以及氯原子的插入，其中R 1，R 2和R 3 它们可以相同或不同，各自代表低级烷基，R 4代表具有至少7个碳原子的烃基; 当糖或部分保护的糖衍生物具有三个以上未保护的羟基时，该方法包括以下步骤：（a）糖或部分保护的糖衍生物与亚硫酰氯在吡啶存在下反应形成过硫酸盐; （b）分离聚亚硫酸盐以除去游离吡啶; 和（c）分离的聚亚硫酸盐与亚硫酰氯在惰性溶剂或悬浮介质中在通式（I）的季盐存在下反应。

摘要： A leak detecting apparatus for detecting a leak in a container such as an oil drums to be tested, comprises ultrasound detecting means;
ultrasound measuring means with an operative connection to said detecting means;
means for altering gas pressure; and
sealing means for sealing the container;
the detecting means being disposed on one side of said sealing means and the measuring means being disposed on another side of said sealing means; the means for altering gas pressure and the said operative connection being disposed within and extending through said sealing means from said one side to said other side; whereby the detecting means can be placed within the container thereby sealing the container and the means for altering gas pressure can provide a difference in gas pressure between the inside and the outside of the container. A related method of detecting a leak in a container comprises providing a difference in the gas pressure between the inside and the ouside of the container and monitoring the ultrasonic emission produced by a leak of gas from the higher pressure side to the lower pressure side, characterised in that a combination of ultrasonic monitoring means and means for causing the pressure difference are introduced into the container itself through an opening therein and sealed, a pressure difference is supplied and ultrasonic emissions are detected inside the container itself.-
