Abstract: A space design for the molecule of hydrocarbon based on the traditional group division method is developed, and a group vector space method (GVSM) for estimating critical property of hydrocarbon is proposed by using the module index of the group vector to characterize the group position in the molecule. Expressions for estimating critical properties Tc,pc and Vc of hydrocarbons are proposed, with the numerical values of relative group parameters presented. The average percentage deviations of Tc,pc and Vc estimation are 0.62, 2.3 and 1.6 respectively.
