摘要:The present disclosure generally relates to the synthesis of an alkoxylated cannabinoid using a double metal cyanide (DMC) catalyst. This procedure affords a novel process for preparing water-dispersible and water-soluble versions of cannabidiol (CBD) and other cannabinoids in high yields through mild reaction conditions.

权利人:AIR PROD & CHEM
摘要:ACETYLENIC ALCOLHOLS, OF A TYPE PRODUCED BY THE REACTION OF A KETONE AND ACETYLENE, ARE REACTED WITH AN ALKALI METAL HYDROXIDE TO PRODUCE ADDUCTS WHICH HAVE UTILITY AS CATALYSTS FOR THE SYNTHESIS OF ACETYLENIC ALCOHOLS. THE REACTION OF THE ALCOHOL AND THE HYDROXIDE TAKES PLACE IN THE PRESENCE OF A SOLVENT, FOLLOWING WHICH THE ADDUCT IS SEPARATED FROM THE SOLVENT.

标 题:Rf-glycols containing two perfluoroalkylthio groups and useful compositions therefrom
发明人：DEAR ROBERT ERNEST ARTHUR; FALK ROBERT ALLAN
权利人:CIBA GEIGY CORP
摘要:Perfluoroalkylthio glycols and esters thereof can be prepared by the free-radical catalyzed addition of a perfluoroalkylthiol to an acetylenic alcohol or ester thereof. The compounds obtained are useful intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. In one embodiment, a perfluoroalkylthio glycol can be reacted with a diisocyanate to obtain a polyurethane containing perfluoroalkylthio groups, which polyurethanes are useful as coatings to provide oil and water repellence to textiles and as additives to plastics to provide mold-release and other desirable properties.
