摘要:The present invention discloses a targeted synthesis method for the synthesis of asymmetric monoesters and/or symmetrical diesters of citric acid through acidic esterification by using boric acid or a boronic acid as a catalyst. The boric/boronic acid simultaneously acts as a catalyst, as well as a 'protecting group' for the tertiary carboxylic acid, and therefore specifically only the asymmetric monoesters or symmetrical diesters are created.

权利人:UNIV CALIFORNIA; SANDIA CORP
摘要:Methods and compositions are provided for synthesizing ionic liquids from lignin derived compounds comprising: contacting a starting material comprising lignin with a depolymerization agent to depolymerize the lignin and form a mixture of aldehyde containing compounds; contacting the mixture of aldehyde containing compounds with an amine under conditions suitable to convert the mixture of aldehyde containing compounds to a mixture of amine containing compounds; and contacting the mixture of amine containing compounds with an acid under conditions suitable to form an ammonium salt, thereby preparing the ionic liquid.

权利人:UNIV LELAND STANFORD JUNIOR
摘要:MOLECULAR NITROGEN IS CONVERTED TO AMMONIA AT ROOM TEMPERATURE AND ATMOSPHERE PRESSURE BY A PROCESS OF CONTACTING NITROGEN OR AIR WITH A TIIV OR TIIII COMPOUND DURING ITS REDUCTION TO A TIII COMPOUND IN A SUITABLE SOLVENT, FOLLOWED BY ADDITION OF A PROTONATING AGENT. THE PROCESS MAY BE USED FOR PURPOSES OTHER THAN THE PRODUCTION OF AMMONIA, SUCH AS SCAVENGING GASES OR SENSING THE PRESENCE OF NITROGEN OR OXYGEN.
