摘要:A process for synthesizing 3,5-dichloroalkylbenzene and recovering 1,3-dichlorobenzene from a starting mixture of 1,3- and 1,4-dichlorobenzenes. The process includes the sequential steps of selectively alkylating the 1,3-dichlorobenzene in the starting mixture; isomerizing a portion of the 2,4-dichloroalkylbenzene produced to 3,5-dichloroalkylbenzene; separating the 1,4-dichlorobenzene from the isomeric mixture of dichlorocumenes; and selectively transalkylating the dichlorocumenes to yield alkylbenzene, 3,5-dichloroalkylbenzene and 1,3-dichlorobenzene. By selectively alkylating only a portion of the 1,3-dichlorobenzene, the reaction products are obtained in good yield and substantially free of undesirable by-products.

标题 :Method of producing graphene and other carbon materials

摘要:The invention provides methods for the combustion synthesis (CS) of graphene by a novel exothermic self-sustained reaction between a refractory ceramic compound and a carbon-containing polymer under an inert gas atmosphere. The synthesis of graphene was confirmed by both transmission electron microscopy and Raman spectroscopy. The graphene produced has very low (<1 wt. %) oxygen content. Fluorocarbon gases released due to decomposition of the carbon-containing polymer in the combustion wave can reduce the ceramic to a gas and mesoporous carbon particles and graphene layers. The method does not require an external energy source because it occurs in a self-sustained synergetic manner after ignition. The methods are flexible in terms of tuning the synthesis conditions for desired products, and the method can be scaled to provide kilogram quantities.

摘要:Three dimensional (3D), porous, Sr(II)/Ir(III) layered double hydroxide materials with a spherical/balls like shape, are composed of nanohexagonal sheets intercalated with 1-(1-hydroxy-4-methyl-2-phenylazo)-2-naphthol-4-sulfonic acid have a number of uses including removing undesirable organic compounds and materials from polluted water. This removal can be accomplished without disturbing the pH of the water, and with high absorption capacity (2000 mg of pollutants/1 mg of LDH). The spherical/ball like materials are easily cleaned and are amenable to being reused several times.

权利人:MARIUS PHARMACEUTICALS INC
摘要:A formulation for drug delivery, providing enhanced modulation of solubility, stability, absorption, metabolism, and/or pharmacokinetic profile of a lipophilic therapeutic agent by formulation with sterols and/or sterol esters, resulting in higher bioavailability of a therapeutic agent administered to a subject in need of such therapeutic agent. The formulation contains a therapeutic agent and a sterol or sterol ester, and can, optionally, further contain a solubilizer and/or an enhancing agent. Also described are pharmaceutical compositions containing the formulations and methods of making and methods of using the formulations and pharmaceutical compositions. Formulations of the disclosure can be constituted to minimize the synthesis of dihydrotestosterone when the therapeutic agent includes testosterone or testosterone esters.
