The invention relates to a method for the preparation of cannabidiol and an intermediate for the preparation of cannabidiol, wherein two intermediates are obtained, namely a silylated olivetol and a silylated olivetol (2) and brominated olivetol (4) which are stable, storable and which do not have undesirable properties or byproducts.

The invention relates to a method for the preparation of cannabidiol and an intermediate for the preparation of cannabidiol, wherein two intermediates are obtained, namely a silylated olivetol and a silylated olivetol (2) and brominated olivetol (4) which are stable, storable and which do not have undesirable properties or byproducts.

Methods are provided for the synthesis of cannabinoids, including cannabidiol (CBD), cannabinol (CBN), cannabichromene (CBC), cannabidiolic acid (CBDA), cannabigerol (CBG), cannabigerolic acid (CBGA), cannabidivarin (CBDV), cannabidibutol (CBD-C4), dihydrocannabidiol (DCBD), tetrahydrocannabivarin (THCV), analogs thereof, and precursors to the foregoing. One method employs phloroglucinol or a phloroglucinol analog as a starting material. The syntheses are stereospecific, efficient, selective, and cost-effective, with little or no potential for generation of THC ((-)-trans-Δ.sup.9-tetrahydro-cannabinol) or any other psychoactive side product. Telescoped syntheses are also provided, as are new cannabinoids, pharmaceutical formulations, and methods of use.

The present disclosure relates to a monomer composition for synthesizing recycled plastic that contains a high-purity aromatic diol compound recovered through recycling by chemical decomposition of a polycarbonate-based resin, a method for preparing the same, and a recycled plastic and molded product using the same.

The present invention relates to heterogeneous catalysts and methods of making and using the same. In various embodiments, the present invention provides a method of making a hydrogenation catalyst including particulate nickel metal (Ni(0)). The method includes calcining first nickel(II)-containing particles in an atmosphere including oxidizing constituents to generate second nickel(II)-containing particles. The method also includes reducing the second nickel(II)-containing particles in a reducing atmosphere while rotating or turning the second nickel(II)-containing particles at about 275° C. to about 360° C. for a time sufficient to generate the particulate nickel metal (Ni(0)), wherein the particulate nickel metal (Ni(0)) is free flowing.

The disclosure relates to a method for depolymerizing lignin. The method includes reacting a lignin compound with a thiol compound to depolymerize the lignin compound and to form a depolymerized lignin product having a reduced molecular weight relative to the lignin compound prior to reacting. The method can further include forming an oxidized thiol reaction product between two thiol groups from one or more thiol compounds, and then reducing the oxidized thiol reaction product to re-form or regenerate the thiol compound for further lignin depolymerization.
