专利号:US-4215099-A 优先权日:1976-11-15 标题 :Ammonia synthesis process 发明人:PINTO ALWYN; WARD STANLEY A 权利人:ICI LTD 摘要:An exothermic gas phase reaction, especially synthesis of ammonia or methanol, is carried out by passing the reactant gas over a catalyst in a first zone in heat exchange with a coolant and then in a second, adiabatic zone and then passing reacted gas directly to a heat recovery zone. Such a sequence of zones affords a higher output of product and better heat recovery than in many previously used sequences, especially when the heat available from the cooled zone is used to pre-heat reactant gas and the heat removed from the gas leaving the adiabatic zone is used in high-grade recoveries such as high pressure steam generation.
专利号:WO-2025202701-A1 优先权日:2024-08-21 标 题 :Marine antifouling paint based on silyl acrylate copolymer synthesis 发明人:LAHEGHI NEJAD FARHAD 权利人:LAHEGHI NEJAD FARHAD 摘要:This invention involves the production of marine anti-fouling paint using the synthesis of silyl acrylate copolymers. One of the most effective anti-algae or anti-fouling paints was self-polishing paints based on acrylate resins containing tributyl tin, which were banned due to the toxicity of their tin compounds. One of the best-introduced alternatives is self-polishing paints based on silyl acrylate copolymers, but their performance is subpar and they have a shorter lifespan. In this invention, silyl acrylate copolymers in a controlled structure, including at least one soft monomer such as butyl acrylate, ethyl acrylate, etc., at least one hard monomer such as methyl methacrylate, 2-methoxyethyl methacrylate, etc. and at least one functional monomer such as triisopropyl silyl acrylate, triisopropyl silyl methacrylate, tertiary-butyl dimethyl silyl methacrylate, and tri-N-butyl silyl methacrylate were synthesized in which monomers or hard monomers were gradually added to the reactor in 2-6 hours.

More specifically, a zinc (II) compound (zinc in the plus two oxidation or valence state), is used as a catalyst in the preparation of para-nitrodiphenylamines via the formanilide process.
专利号:US-2002184969-A1 优先权日:2001-03-29 标 题 :Combinatorial synthesis of particulate materials 发明人:KODAS TOIVO T; HAMPDEN-SMITH MARK J 摘要:Methods for fabricating and analyzing particulates having a varying material property such that particulates having a selected desirable material property can be identified. The particulates can be analyzed to determine the particulates having the best properties for a particular application. The particulates can be metals, inorganic compounds, organic compounds and composites. The method of the present invention enables the rapid and economical fabrication and screening of a large number of different compositions.
