5-Amino-5-deoxy-1,2-O-isopropylidene- alpha -D-glucofuranose is conveniently prepared by a hydride reduction of 5-azido-5-deoxy-1,2-O-isopropylidene- alpha -D-glucuronolactone and can readily be converted to nojirimycin, deoxynojirimycin or homonojirimycin.

A process for the chlorination of sucrose or a derivative thereof, comprises reaction of the sucrose or derivative thereof with thionyl chloride and a nitrogen base at a ratio of about 1 molar equivalent (ME) of thionyl chloride and about 1 ME of base for every ME of free hydroxyl, in a non-reactive moderately polar solvent. The process is particularly suitable for the preparation of sucralose.

Aqueous thiocarbonate solutions are stabilized by the addition of base, sulfide and/or polysulfide and the stability and safety of the more concentrated solutions containing 1 weight percent or more equivalent CS2 as a thiocarbonate are achieved as reflected by significant reduction of CS2 partial pressure in such solutions. Such stabilized thiocarbonate solutions are useful for the control of pes...

A method of making self-supporting ceramic composite structures having filler embedded therein includes infiltrating a permeable mass of filler with polycrystalline material comprising an oxidation reaction product obtained by oxidation of a parent metal such as aluminum and optionally containing therein non-oxidized constituents of the parent metal. The structure is formed by placing a parent met...

An environmental chamber for providing thermal stress screening is comprised of a plurality of modular components which may be quickly assembled and disassembled for ease of maintenance and repair. In particular, a heater/cooling unit is coupled by means of a plurality of quick release lockable fasteners to a plenum miodule. The plenum module in turn is coupled by means of additional quick release...

In-vivo bone density measuring system using a modified emission computed tomographic gamma camera arrangement for detecting radiation from two separate sources located outside of the body of the patient and oppositely disposed to the gamma camera during rotation of the gamma camera and sources means about the patient for obtaining tomographic data.
