  • Patent number: 9211529
    Abstract: Catalytic processes to produce a reaction product comprising 1-butanol by contacting a reactant comprising ethanol with a catalyst composition under suitable reaction conditions are provided. The catalyst composition may comprise a hydroxyapatite of the Formula (MwM?xM?yM??z)5(PO4)3(OH), wherein M is Mg; M? is Ca; M? is Sr; M?? is Ba; w is any number between 0 and 1 inclusive; x is any number from 0 to less than 0.5; y is any number between 0 and 1 inclusive; z is any number between 0 and 1 inclusive; and w+x+y+z=1. Base-treated catalyst compositions may be used. Also provided are processes for contacting an initial catalyst composition comprising the hydroxyapatite with a base to produce a base-treated catalyst composition, and the base-treated catalyst compositions so obtained.

  • Publication number: 20150110710
    Abstract: The present invention relates to a process for manufacturing low-dusting, smoothly-discharging, easily dispersible, powders such as pigmentary titanium dioxide that resist compaction, aging, lumping, and/or caking. Particularly, the present invention relates to a process for treating powders such as pigmentary titanium dioxide with ammonia or a similarly basic substance prior to or during agglomeration to produce a powder with improved bulk handling properties.
