专利号:US-5886196-A 优先权日:1996-01-12 标 题 :Method of catalyzing condensation reactions 发明人:FUERBRINGER CLAUDE 权利人:ROCHE VITAMINS INC 摘要:Hydrogen bis(oxalato)borate of the formula ##STR1## is used as a protonic acid catalyst in condensation reactions, such as Friedel-Crafts condensations, vinyl ether condensations of acetals with vinyl or propenyl ethers and acylations of phenols. The products of such condensations are, for example, dihydro-vitamin K 1 monobenzoate, d,l-α-tocopherol, various intermediates in the synthesis of carotenoids as well as d,l-α-tocopherol acetate. As a result of the use in accordance with the invention of hydrogen bis(oxalato)borate various disadvantages associated with the use of other protonic acid catalysts, e.g. problems with corrosion, toxicity and environmental contamination, are avoided. The novel catalyst has advantages with respect to selectivity, yields, amounts required as well as working up after completion of the respective condensation.
专利号:WO-9842627-A1 优先权日:1997-03-20 标题 :Sol-gel synthesis of alkali-free borosilicate glass 发明人:VARMA KARIKATH SUKUMAR 权利人:PILKINGTON PLC; VARMA KARIKATH SUKUMAR 摘要:A method of producing metalloborates (including silicoborates) comprising reacting a trisubstituted boroxine with a tetrasubstituted orthosilicate or metal alkoxide in the substantial absence of hydroxyl groups to form a sol-gel so that the rate of reaction may be controlled and that the time taken for the reaction mixture to form a gel is substantially increased. The reaction may be carried out in the presence of a solvent and of a catalyst.
专利号:US-9246173-B2 优先权日:2012-11-16 标题 :Process for synthesis of hybrid siloxy derived resins and crosslinked networks therefrom 发明人:GERBEC JEFFREY A 权利人:MITSUBISHI CHEM CORP 摘要:A hybrid siloxy derived resin and a method of making them and a method of applying them as a benign passivant on electrochemical electrodes is provided. These resins are made by the process of reacting a silane and an alkaline, transition metal or metalloid alkoxide, in the presence of a lewis acid. The methods described do not require further purification steps; heat; or strong acid/base catalysis to initiate hydrolysis.
专利号:US-6824753-B2 优先权日:2001-04-24 标 题:Organoboron route and process for preparation of boron nitride 发明人:PAINE ROBERT T; KROENKE WILLIAM J; PRUSS EUGENE A; WOOD GARY L; JANIK JERZY F 权利人:STC UNM 摘要:An organoboron route and process for preparation of boron nitride utilizing aerosol assisted vapor phase synthesis (AAVS) wherein organoboron precursors are nitrided in one or two heating steps, and wherein a boron oxide nitride intermediary composition is formed after the first heating step and may be further nitrided to form resultant spheroidal boron nitride powders including spheroidal particles that are smooth, bladed, have protruding whiskers, and are of turbostratic or hexagonal crystalline structure.
