专利汇可以提供Recording and preserving method for information on chemical reaction专利检索,专利查询,专利分析的服务。并且PURPOSE: To record and preserve the information on the structural change of chemical substance so that they can be processed by a computer, by discriminating the connections between nodes existing in common and peculiar to the structures of the starting substance and the produced substance.
CONSTITUTION: When the hydrolysis, etc. is applied to ethyl acetate, for example, according to the reaction formula I, the numbers 1W11 are added to the nodes of atoms and the atomic groups of the structure of the starting substance based on the formula II. For the structure of the starting substance end the produced substance which are topologically put on each other, the common node connections are shown by the solid lines together with the node connection proper to the produced substance only shown by the dotted lines and the node connections proper to the starting substance only shown by another type of lines respectively. Thus a false transition structure shown in the formula III is obtained with connections shown with discrimination. In such a simple constitution or based on a list of these structures, the information on the structural change of the chemical substance can be recorded including the starting substance and the produced substance so that they can be processed by a computer without increasing the recording capacity.
