CATALYTICALLY ACTIVE BODY FOR THE SYNTHESIS OF DIMETHYL ETHER FROM SYNTHESIS GAS

The invention relates to a catalytically active body for the synthesis of dimethyl ether from synthesis gas. In particular, the invention relates to an improved catalytically active body for the synthesis of dimethyl ether, whereby the components of the active body comprise a defined particle size distribution. Furthermore, the present invention concerns a method for the preparation of a catalytically active body, the use of the catalytically active body and a method for preparation of dimethyl ether from synthesis gas.

Translucent antacid suspension

An essentially translucent antacid composition is formed by an aqueous colloidal aluminum hydroxide gel wherein the average particle size of the aluminum hydroxide is less than about 0.5 microns, preferably less than about 0.1 microns, and more preferably less than about 0.01 microns. The suspension is further preferably mixed with a polyol, such as sorbitol or maltitol, to enhance the translucency. The weight ratio of polyol to aluminum hydroxide gel (USP) ranges from about 0.5:1.0 to about 4.0:1.0.
