Abstract: The present invention provides an efficient method of synthesizing and purifying dianhydrohexitols such as dianhydrogalactitol. In general, as applied to dianhydrogalactitol, the method comprises: (1) reacting dulcitol with a concentrated solution of hydrobromic acid at a temperature of about 80° C. to produce dibromogalactitol; (2) reacting the dibromogalactitol with potassium carbonate in t-butanol to produce dianhydrogalactitol; and (3) purifying the dianhydrogalactitol using a slurry of ethyl ether to produce purified dianhydrogalactitol. Another method produces dianhydrogalactitol from dulcitol; this method comprises: (1) reacting dulcitol with a reactant to convert the 1,6-hydroxy groups of dulcitol to an effective leaving group to generate an intermediate; and (2) reacting the intermediate with an inorganic weak base to produce dianhydrogalactitol through an intramolecular SN2 reaction. Other methods for the synthesis of dianhydrogalactitol from dulcitol are described.

Abstract: The present disclosure discloses an ?-alumina carrier, comprising the elements of lanthanum and silicon both dispersed in the interior and on the surface of the carrier. The mass ratio of the element of lanthanum to the element of silicon is in the range from 0.1:1 to 20:1. The inventors of the present disclosure have made extensive researches into the field of the silver catalyst and alumina carrier thereof, and added the elements of lanthanum and silicon (i.e., bulk phase addition) in preparing the alumina carrier used in the silver catalyst. The carrier thus obtained contains the elements of silicon and lanthanum both in the interior and on the surface thereof, and has improved specific surface area and strength. The silver catalyst prepared with the carrier can react in a low reaction temperature (has a high reaction activity) and has a high selectivity in producing ethylene oxide through oxidation of ethylene.
