Title: Extraction of carboxylic acids with tin compounds
Filed: 2012-05-09
Abstract: A method of removing a carboxylic acid from a liquid including a tertiary amide solvent includes: A) forming an extraction medium including an acid-extracting tin species and an extraction solvent that is immiscible with the tertiary amide solvent; B) subsequently contacting the liquid with the extraction medium, forming a phase including a de-acidified tertiary amide solvent and a phase including the extraction solvent; and C) removing the phase including the extraction solvent, to afford a liquid including the de-acidified tertiary amide solvent. The acid-extracting tin species is one or more tin species obtainable by reaction of a di(hydrocarbyl)tin oxide with less than one equivalent of a carboxylic acid, tin species obtainable by reaction of a 1,3-diacyloxy-1,1,3,3-tetra-(hydrocarbyl)distannoxane with an aqueous base. A method of preparing a sucralose-6-acylate includes using the foregoing method to remove a carboxylic acid from a liquid including a tertiary amide solvent and the sucralose-6-acylate.

Abstract: Method and apparatus for detecting and obtaining information about (particularly locating) an event. i.e. a change in a variable, for example an increase in the concentration of a fluid as a result of a leak, a change in the physical position of a movable member such as a valve, a change in temperature, or a change in pressure. In a preferred embodiment, three conductors follow an elongate path. One of them (called the locating member (11)) comprises a plurality of spaced-apart resistors (111) separated by low resistance intermediate components (112), so that the locating member has known impedance characteristics along its length. The second conductor (12) is connected to one end of the locating member, but is otherwise insulated from the locating member. When the event occurs, connection is made between the locating member (11) and the second conductor (12) at one or more of a plurality of available connection points, each of which lies between a pair of resistors. With the aid of the third conductor (16), a current of known size is passed through, and the voltage drop is measured between, the connection point and one end of the locating member. The location of the event can then be calculated.
