标 题 :Alkoxylation of cannabidiol and other cannabinoids
发明人：LAHASKY SAMUEL; SHARP KIP DOUGLAS; SLIKTA ALBERTO; PRESTRIDGE BRITNEY HEBERT; BARKER EMILY MATTHEWS; RICHARDSON RYAN
权利人:INDORAMA VENTURES OXIDES LLC
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.

标 题 :Synthesis of hydroxyl-terminated polybutadienes using glycol ether solvents
发明人：KNIFTON JOHN F; MARQUIS EDWARD T
权利人:TEXACO CHEMICAL
摘要:Disclosed is an improvement in a process for polymerizing 1,3-butadiene selectively to form relatively low molecular weight hydroxyl-terminated polybutadiene oligomers in the presence of an aqueous solution of hydrogen peroxide which comprises the use of a glycol ether solvent to produce butadiene oligomers having a high degree of OH functionality and suppression of formation of solid or gel-type insoluble rubber by-products.

权利人:GREAT LAKES CHEMICAL CORP
摘要:A method of preparing tetrabromobenzoate compounds from tetrabromophthalic anhydride by reacting tetrabromophthalic anhydride with alcohol in the presence of a decarboxylation catalyst. The reaction may be carried out in an excess of alcohol, or with a near stoichiometric amount of alcohol by performing the reaction in an inert solvent.

权利人:OREAL
摘要:A method for managing skin tone comprising reducing the synthesis of melanin by applying a skin treatment composition to skin. The skin treatment composition may include about 0.1 to about 25 wt. % of acetyl trifluoromethylphenyl valylglycine; about 0.5 to about 30 wt. % of a polyol; about 0.1 to about 30 wt. % of a silicone, fatty compound, or a mixtures thereof, wherein the skin treatment composition is an emulsion, and all weight percentages are based on the total weight of the skin treatment composition.
