    Abstract: The zeolite catalyst is provided for the alkylation of toluene with methanol to selectively produce styrene and ethylbenzene. The zeolite catalyst is an X-type zeolite modified sequentially, first by ion-exchange with alkali metals, such as cesium, to replace all exchangeable sodium from the zeolite, and then by mixing the modified zeolite with borate salts of a metal such as lanthanum, zirconium, copper, zinc or the like. The initial zeolite composition has a Si to Al molar ratio of approximately 1 to 10, and is preferably either zeolite X or zeolite 13X. The zeolite composition is ion-exchanged with cesium to replace at least 50% of the exchangeable sodium in the zeolite composition. The ion-exchanged zeolite composition is then mixed with a borate salt to form the zeolite catalyst for the alkylation of toluene with methanol for the selective production of styrene and ethylbenzene.

  • Patent number: 7829155
    Abstract: The present invention provides a new monomer and methods of using the monomer to fabricate robust polymer surface coatings with controlled thicknesses between 1 and 5 nanometers. The coatings are composed of a new material containing polymerized monomers of 4-vinylbenzenepropanethiol. The polymer surface coating may be applied to metal and silicon. The method includes exposing a metal substrate to a solution of the monomer in hexanes in order to deposit a monolayer of the monomer onto the metal surface. The substrate is then irradiated with ultraviolet radiation in order to graft a thin polymer coating onto the surface. The procedure can be repeated in order to control the thickness of the coating between about 1 nm and 5 nm. Alternatively, thermally initiated polymerization or deposition of partially oligomerized monomers onto the surface provides nanothin coatings with identical performance.

  • Patent number: 6849771
    Abstract: The invention relates to a process for converting 1-phenylethanol into styrene, which process involves: (1) contacting a feed containing 1-phenylethanol, organic acid and 2-phenylethanol with a catalyst to obtain a product containing styrene, and (2) removing ester compounds based on 2-phenylethanol and organic acid from the product of step (1), in which process the feed of step (1) has a molar ratio of organic acid to 2-phenylethanol of at least 1:10.
