The technical requirements to the propellant of rocket engine using chemical energy are developed from the point of its performance, design and the exploration. The propellant, i.e. to get higher energy, to increase the cooling effect, and to be used in safety and comfort should be made. So from these aspect the technical requirements were written by the factors of physical chemistry. And the propellant combination used recently in Launch vehicles is liquid Oxygen and Kerosene, the main characteristics of this Kerosene as a fuel were reviewed. The toxicity and the safety of Kerosene, in specially, require the attention of the users. Also, it would be used in the development of Korean Kerosene by the comparative review of the several Kerosenes in Abroad.
