In 2022,Jiao, Nianming; Yuan, Yanyan; Yao, Yuan; Liu, Long; Zhang, Yanqiang published an article in Fuel Processing Technology. The title of the article was 《Strained carbocycle based hypergolic ionic fuels with the improved energy capacity》.Product Details of 7051-34-5 The author mentioned the following in the article:
Different from the previous nitrogenous groups, we present a new strategy of improving the ionic liquids (ILs) energy capacity by introducing the strained carbocycles. The ILs with three- and/or four-member carbocycles were prepared, and their physicochem. properties as rocket fuels were studied. The ignition tests show that all of these ILs have the expected hypergolic reactivity with the oxidizer (white fuming HNO3). In virtue of the strained cyclopropane and cyclobutane substituents, the resulting hypergolic ILs possess better energy properties (heats of formation 0.784-1.968 kJ g-1; specific impulses 313.0-315.7 s) and densities (1.03-1.15 g cm-3) than the corresponding ILs with n-alkyl substituents. This strategy of introducing strained ring groups into hypergolic ILs gives a new approach to improve energy properties of hypergolic ILs. The experimental part of the paper was very detailed, including the reaction process of (Bromomethyl)cyclopropane(cas: 7051-34-5Product Details of 7051-34-5)
(Bromomethyl)cyclopropane(cas: 7051-34-5) is used as a synthetic building block for the introduction of the cyclopropylmethyl group. It was also used in the synthesis of 1,4-dienes via iron-catalyzed cross-coupling with alkenyl Grignard reagents.Product Details of 7051-34-5
