Analysing of boron compounds used in rocket fuels and development of manufacturing technology method for diborane

Rocket propellant is the reaction mass of a rocket.The energy required can either come from the propellants themselves, as with a chemical rocket, or from an external source, as with ion engines. Chemical rockets can be grouped by phase. Liquid fuel rockets use propellant in the liquid phase. The main types of liquid propellants are storable propellants, which lead to be petroleum, hypergolic, and cryogenic propellants. It is showed that types of mixture and their chemical and physical properties based on mixture compounds and ratio in this thesis. Boron compounds has different application in industry and studies show that it can use liquid rocket propellant as bipropellant category. Boron have included different methods in the other words, sometimes it is generated directly as propellant or it can use as hydrogen storage in mixture. Also, development of diborane technology for liquid rocket fuel mixtures: Diboranes are very toxic and production technologies are also difficult. The production details for technology are given this thesis. The process has been drawn. The most important advantage of the patented value process is that the reaction medium is a special solvent that can reach inert and high temperature and allow controlled breakdown of sodium borohydride in an oxygen-free environment. The purpose of this thesis is to improve new alternative rocket liquid propellants which is used boron compounds such as ammonia borane, diborane, pentaborane, dehaborane and improve to production technology of diborane, discuss their capabilities, their physical and chemical properties.
