标题 :Synthesis of r-glucosides, sugar alcohols, reduced sugar alcohols, and furan derivatives of reduced sugar alcohols
发明人：SANBORN ALEXANDRA; BINDER THOMAS P

摘要:Disclosed herein are methods for synthesizing 1,2,5,6-hexanetetrol (HTO), 1,6 hexanediol (HDO) and other reduced polyols from C5 and C6 sugar alcohols or R glycosides. The methods include contacting the sugar alcohol or R-glycoside with a copper catalyst, most desirably a Raney copper catalyst with hydrogen for a time, temperature and pressure sufficient to form reduced polyols having 2 to 3 fewer hydoxy groups than the starting material. When the starting compound is a C6 sugar alcohol such as sorbitol or R-glycoside of a C6 sugar such as methyl glucoside, the predominant product is HTO. The same catalyst can be used to further reduce the HTO to HDO.

标题 :Nanocatalyst anchored onto acid functionalized solid support and methods of making and using same

摘要:Supported catalysts include a solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. Active catalyst particles are supported on the functionalized support material. The acid functionalized support material is made by reacting a solid support with an inorganic acid containing agent such as sulfuric acid or para-toluene sulfonic acid. An organic anchoring agent is used to form and anchor catalyst nanoparticles to the acid functionalized support material. The supported catalyst can be sized and shaped for use in any type of reactor, including a fixed bed or fluidized bed reactor. The methods of the present invention also include a process for the direct synthesis of hydrogen peroxide using the supported catalyst.

标题 :Beta-chloroethylsulfonylmethyl-benzoic halides as intermediates
发明人：SCHLAEFER LUDWIG; HAEHNLE REINHARD
权利人:HOECHST AG
摘要:New beta -chloroethylsuflonylmethyl-benzoic acid halides which can serve as fibre-reactive anchors for thesynthesis of novel organic, water-soluble compounds, preferably dyestuffs, having fibre-reactive and fibre-finishing properties, such as preferably dyestuff properties, and containing, as a fibre-reactive group, one or two beta -chloroethylsufonylmethylbenzoic acid amide groups. For the synthesis of these novel fibre-finishing compounds, said new beta -chloroethylsulfonylmethyl-benzoic acid halide compounds are reacted with an organic, water-soluble compound having fibre-finishing properties and continuing one or two amino groups. Also precursors of the fibre-finishing, fibre-reactive compounds, containing said beta -chloroethylsulfonylmethyl-benzxoic acid amid grouping, can be employed for their synthesis. The novel fibre-finishing compounds can be applied onto suitable fibre materials, such as especially cellulose fibre material and natural or synthetic polyamide fibre materials, and fixed on these fibre materials in a manner similar to application and fixation methods usual in the technique for fibre-reactive compounds. The fibre-finished material, such as dyed material, shows very good wet fastnesses.

标题 :Process for preparation of azo dyestuffs by coupling in presence of aromatic sulphonic acid-formaldehyde reaction product

摘要:Dyestuff dispersions and dyestuff solutions free from salt or at least having a low salt content are obtained in that the diazotization is carried out with addition of free dispersing agent acid to which, after the synthesis, either no basic agents are added or basic agents are added only up to a pH value of 3. The disclosed process gives dyestuff compositions of low salt content and results in readily dispersible dyestuffs when water insoluble dyestuffs are prepared and stable solutions when water soluble dyestuffs are prepared. The process is widely applicable and chemical constitution of the dyestuffs is conventional.
