摘要:A method for green synthesis of uniform- and large-particle-size polystyrene particles, comprising steps of: prepolymerizing styrene at 70â–¡ to 75â–¡ for 1 h to 6 h in advance while stirring, adding divinylbenzene dissolved with initiators to the styrene, and stirring for 10 min to 30 min to obtain oil phase; heating lactic acid or an aqueous solution of lactic acid to 70â–¡ to 80â–¡, adding the oil phase to dispersed phase by a constant-pressure device, maintaining the temperature for 2 h, heating to 80±5â–¡ and then maintaining the temperature for 1 h, and heating to 85±5â–¡ and then maintaining the temperature for 3 h to 6 h, to obtain polystyrene particles with a uniform particle size ranging from 0.7 mm to 2.0 mm.

摘要:A method including reducing a particle size of lignin particles to an average particle size less than 40 nanometers; after reducing the particle size, combining the lignin particles with a polymeric material; and forming a structure of the combination. A method including exposing lignin to a diazonium precursor including a functional group; modifying the lignin by introducing the functional group to the lignin; and combining the modified lignin with a polymeric material to form a composite. An apparatus including a composite of a polymer and lignin wherein the lignin has an average particle size less than 100 micrometers.

权利人:MOBIL OIL CORP
摘要:A method of preparing a composition comprising a crystalline zeolite and a porous matrix material which comprises coating at least a portion of the surface of at least one of the components selected from the group consisting of said zeolite and said porous matrix material with a solid or liquid coating material which is substantially retained during any subsequent processing steps prior to its positive intentional removal, which occurs after the compositing step, intimately compositing said zeolite with said matrix material and removing said coating material; the composition prepared therefrom and hydrocarbon conversion employing the composition as a catalyst.
