标题:迈向更安全的火箭燃料:超高分子量的咪唑基亚基-硼烷化合物可代替肼衍生物
摘要:目前,有毒和挥发性肼衍生物仍是液体双推进剂的主要燃料选择,尤其是在某些传统的火箭推进系统中.因此,寻找更安全的高取代氢燃料替代肼衍生物一直是最具挑战性的任务之一.在这项研究中,已合成并表征了六种具有两性离子结构的咪唑基亚烷基-硼烷化合物,并对其超高活性进行了研究.如所期望的,这些化合物在与白色发烟硝酸(wfna)接触时表现出快速的自燃.其中,化合物5具有出色的综合性能,包括宽的液体工作范围(-70-160oc),优异的装载密度(0.99 G Cm-3),使用wfna的超快点火延迟时间(15毫秒)和高比冲(303.5 S),这表明在液体双推进剂配方中作为更安全的高离岸燃料,有广阔的应用前景.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.

摘要:A nonmetallic compound having an ionic bond with a halide ion is used as a catalyst for living radical polymerization. Even if a radical initiator is not used, a monomer can be subjected to a radical polymerization to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced, and it is made possible to prevent adverse effects of using a radical initiator (such as side reactions). The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor, etc. The catalyst can be applied to various monomers and enables synthesis of high molecular weight polymers.

摘要:The present invention relates to a method for the depolymerization of a polyurethane mass, preferably thermoset polyurethane. The method comprises four main steps: i) mixing the polyurethane mass with a depolymerization reaction medium comprising an ionic liquid in a proportion equal to or greater than 50% w/w with respect to the total weight of said medium, a superbase as a catalyst, and a nucleophilic agent in a proportion equal to or less than 15% w/w with respect to the total weight of said medium, subjecting said mixture to a temperature between 50-100°C for between 2 minutes and 10 hours; ii) adding a mass of a protic molecular solvent in an amount between 4 and 40 times the weight of the depolymerization reaction medium; iii) subjecting the mixture from step ii) to a temperature between 20-60°C for at least 1 hour; and iv) separating the fractions obtained in step iii), namely, a semisolid fraction comprising at least a polyol mass for reuse in the synthesis of a new polyurethane, and a single-phase liquid fraction comprising at least the ionic liquid and the basic catalyst, for their reuse in a new process for polyurethane depolymerization.
