    摘要: A process for producing a monoalkylated aromatic product in a reactor by reacting a mixed phase mixture of an alkylatable aromatic compound feedstock with another feedstock comprising alkene component in a reaction zone containing an alkylation catalyst. An effluent comprising the monoalkylated aromatic product and polyalkylated aromatic compounds exits from the reaction zone in liquid phase. The polyalkylated aromatic compounds can be separated as feed stream for transalkylation reaction in a transalkylation reaction zone.

    摘要: A process is disclosed for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones, each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene are introduced into the first alkylation reaction zone. The first and second alkylation reaction zones are operated under conditions of temperature and pressure effective to cause alkylation of the aromatic compound with the alkene in the presence of the alkylation catalyst, the temperature and pressure being such that the aromatic compound is at least partly in the liquid phase. The alkylation catalyst in the first alkylation reaction zone, which may be a reactor guard bed, has more acid sites per unit volume of catalyst than the alkylation catalyst in the second reaction zone.

    摘要: A wall mount assembly for mounting to a building is described. The wall mount assembly includes a base member having a front surface and a rear surface and having a wall extending about an outer periphery and inwardly from the rear surface. The base member also includes at least one edge recessed rearwardly from the front surface defining a recessed portion therein. The edge of the recessed portion also defines mounting apertures, mounting holes and/or mounting surfaces spaced about the recessed portion. An annular flange extends rearwardly from the recessed portion. An insert member and/or a cover member mount to either one of the mounting apertures, mounting holes and/or mounting surfaces for creating an aesthetic appearance.

    摘要: A molding assembly having a hanger member fixedly securable to an inner or outer wall of a building and a decorative molding insert member releasably engageable with the hanger member. The molding insert member is supported at a lower edge portion by a lower J-channel of the hanger member. An upper L-shaped portion of the insert member is supported by a depending lip portion of the hanger member which forms a second channel such that no external fastening elements are required to secure the molding insert member to the hanger member. The insert member can be quickly and easily releasably engaged within the J-channel and the second channel without the need for special tools. In an alternative preferred embodiment the insert member includes a lip portion which is adapted to slidably engage an under surface of an adjacently positioned insert member to provide an even more continuous appearance for adjacently positioned insert members. An end cover is also disclosed for covering an exposed end portion of the molding assembly when the end portion is secured to a section of a wall where one or more ends of the molding assembly do not abut another wall portion extending perpendicularly from the molding assembly. In an alternative embodiment of the end cover, the end cover includes a shoulder portion formed to protrude from a lower lip portion which engages a notch formed in a lip of a lower J-channel of a hanger member of the present invention. In this manner, once the end cover is releasably secured to the hanger member, the end cover cannot be slidably urged-off of the hanger member such as by thermal expansion of one or more sections of molding insert members.

    摘要: An electrical block trim assembly that has a mount, a decorative ring, and a separate electrical box is provided. The mount has a base adapted to be secured to an exterior surface of a structure. The mount also has a housing extending from the base with a top portion that has an opening. Exterior covering, or siding, is attached to the exterior surface to surround a portion of the mount. A decorative ring is secured to the mount over the siding to conceal the edges of the siding that are adjacent to the mount. The decorative ring has an inner perimeter that is adjacent to the housing. An electrical box having walls with an upper portion is securely received and retained within the opening. The electrical box is interposed between the exterior surface and the top portion. The electrical box may be constructed of a different material than the mount and decorative ring.

    摘要: A surround molding assembly is disclosed for a doorway window or window of a structure such as a residential home or commercial building. The surround molding assembly may include various embodiments of pilasters, end and corner members, and mantel members that may be fastened to one another or the structure with limited use and visibility of external fasteners. In one embodiment, a decorative molding strip includes a base strip and a decorative strip interconnected by a living hinge. The decorative strip may be pivoted about the living hinge to a closed position over the base strip to hide internally located fasteners. In another embodiment an extension cap is interconnected between a corner member and a decorative molding strip or pilaster without external fasteners. As a result, the molding assemblies of the present invention simplify assembly while providing an aesthetically pleasing appearance free of external fasteners.
