Chemical search association library system and building method thereof

The invention relates to a chemical search association library system and a building method thereof. The chemical search association library system comprises a chemical substance primary library subsystem, and further comprises one or more of a reactant property library subsystem, a product property library subsystem and a reactant and product property library subsystem; and the reactant property library subsystem, the product property library subsystem and the reactant and product property library subsystem are respectively associated with the chemical substance primary library subsystem via respective index addresses stored in the chemical substance primary library subsystem. With the chemical search association library system provided by the invention, users can learn the substances with other properties associated with the primary chemical substance while learning the primary chemical substance, and also can learn the equation of reaction between the substances with other properties and the searched chemi
