标题:Synthesis of hydrogen peroxide
发明人：BECKMAN ERIC J; HANCU DAN
权利人:UNIV PITTSBURGH
摘要:A method for synthesizing hydrogen peroxide comprises the step of: mixing an analog of a secondary alcohol that is soluble with carbon dioxide with a free radical initiator and oxygen in carbon dioxide to generate hydrogen peroxide. Another method of synthesizing hydrogen peroxide comprises the step of: mixing hydrogen, oxygen and a CO 2 -philic catalyst in carbon dioxide phase. The CO 2 -philic catalyst is soluble or miscible in carbon dioxide and is suitable to catalyze the reaction of hydrogen and oxygen to produce hydrogen peroxide. The method also comprises the step of reacting the hydrogen and oxygen to produce hydrogen peroxide.

标题 :Process for preparation of azo dyestuffs by coupling in presence of aromatic sulphonic acid-formaldehyde reaction product
发明人：MOLLS HANS-HEINZ; SCHIWY WILLY; HORNLE REINHOLD; NEBELING REINHARD
权利人:BAYER AG
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.
