专利号:US-4426540-A 优先权日:1976-06-10 标 题 :Synthesis of vinyl ethers 发明人:SHACKELFORD SCOTT A; MCGUIRE RAYMOND R; COCHOY ROBERT E 权利人:US AIR FORCE 摘要:Vinyl ethers are prepared by reacting divinyl ether with a primary alcohol in the presence of a catalytic amount of red mercuric oxide and trifluoroacetic acid. The vinyl ethers so produced are particularly useful as monomers which can be polymerized into energetic macromolecular binder materials with excellent mechanical, physical and energetic properties.
专利号:US-5449835-A 优先权日:1994-11-14 标题 :Synthesis of bis(2,2-dinitropropyl) formal (BDNPF) 发明人:HAMILTON R SCOTT; WARDLE ROBERT B 权利人:THIOKOL CORP 摘要:A nonsolvent process of synthesizing bis(2,2-dinitropropyl)formal (BDNPF) is disclosed. In the process, 2,2-dinitropropanol (DNPOH) is reacted at low temperature with a formaldehyde source in the presence of a protic acid catalyst, such as H 2 SO 4 , HCl, H 3 PO 4 , or HBr. To inhibit byproduct formation, the reaction temperature is maintained from about -30° C. to 30° C. Upon completion of the reaction, the reaction solution is quenched with water and washed with an aqueous hydroxide ion solution. The hydroxide ion concentration should be sufficient to neutralize the protic acid catalyst during the quenching step and to solubilize unreacted 2,2-dinitropropanol as well as other aqueous soluble byproducts in the reaction solution. The BDNPF product is extracted with a low boiling temperature polar organic solvent, such as methyl tert-butyl ether (MTBE) or equivalent solvent. The organic solvent is evaporated to yield usable BDNPF product. The resulting yield is at least 60% based on the starting quantity of 2,2-dinitropropanol.
专利号:US-5648556-A 优先权日:1994-11-14 标题:Synthesis of bis(2,2-dinitropropyl)acetal (BDNPA) 发明人:HAMILTON R SCOTT; WARDLE ROBERT B 权利人:THIOKOL CORP 摘要:A nonsolvent process of synthesizing bis(2,2-dinitropropyl)acetal (BDNPA) is disclosed. In the process, 2,2-dinitropropanol (DNPOH) is reacted at low temperature with an acetaldehyde source in the presence of an acid catalyst, such as a Lewis acid catalyst or protic acid catalyst. To inhibit by product formation, the reaction temperature is maintained from about -30° C. to 30° C. Upon completion of the reaction, the reaction solution is quenched with water and washed with an aqueous hydroxide solution. The hydroxide concentration should be sufficient to neutralize any acid formed during the quenching step and to solubilize unreacted 2,2-dinitropropanol as well as other aqueous soluble byproducts in the reaction solution. The BDNPA product is extracted with methyl tert-butyl ether (MTBE) or equivalent solvent. The organic solvent is evaporated to yield usable BDNPA product. The resulting yield is at least 50% based on the starting quantity of 2,2-dinitropropanol.
