摘要:The present invention relates to methods of preparing carbon monoxide (CO) and hydrogen (H 2 ) by reacting biomass, a biomass component (e.g., lignin, ligno-cellulose, cellulose, hemiceullose or combination thereof) or a carbohydrate from any source with a polyoxometalate catalyst such as H 5 PV 2 Mo 10 O 40 , or solvates thereof, in the presence of a concentrated acid, under conditions sufficient to yield carbon monoxide (CO); followed by electrochemical release of hydrogen (H 2 ). The carbon monoxide (CO) and hydrogen (H 2 ) may be combined in any desired proportion to yield synthesis gas (Syngas). The present invention further relates to methods for preparing H 2 , CO and formic acid/formaldehyde from biomass, a biomass component and/or from carbohydrates.

标题 :Labelled cardiotonic glycosides for use in radioimmunoassay
发明人：COOMBES ROBERT F
权利人:CURTIS NUCLEAR CORP
摘要:Disclosed are radioactive cardiotonic glycosides and a process of making such glycosides, the compounds being useful for radioimmunoassay of body fluids for cardiotonic glycoside content. n The novel synthesis comprises reaction of a hydroxyl group of the sugar with a dicarboxylic acid derivative such as a diacid, diacid anhydride or a diacyl halide and thereafter reacting the free carboxylic group with a compound which will undergo electrophilic substitution reactions. A radioactive isotope, preferably 125 I, is reacted via electrophilic substitution with the compound to form the radioactive cardiotonic glycoside.
