1,2-Propylene glycol has been chloroxypropylated with epichlorohydrin. The structures and compositions of synthesized oligomers having different average degrees of chloroxypropylation have been determined by IR and (1)H NMR spectroscopy. The physicochemical parameters of the oligomers have been determined, and their surface activity has been studied. The same characteristics have been found for 1,2-propylene glycol chloroxypropylates phosphatized with H(3)PO(4). The ability of these products to retard the evaporation of gasoline during storage has been revealed.
