A method for predicting gas chromatographic retention indices of a class of compounds O ALKILALKILFTORFOSFONATOV

摘要

A method for predicting gas chromatographic retention indices class O-alkylalkylfluorophosphonates compounds based additive system, comprising converting asymmetric structure compound as two compounds symmetric structure relative to the selected center of symmetry and defining a retention index as the half-sum retention indices of the compounds symmetric structures, characterized in that as the center O-symmetry class alkylalkylfluorophosphonates compound is selected such carbon atom in O-alkyl p adikale in branching which has two different alkyl moiety or an alkyl moiety and a hydrogen atom; Further produce structural changes in the compound of two compounds in the same class, O-alkylalkylfluorophosphonates symmetrical structure with respect to the carbon atom selected using only these fragments and subjecting the structural change of the rest of the molecule.
