Claims18
A deicing composition comprising an effective amount of a compound to depress freezing point of a mixture of said deicing composition and any ice, said compound is selected from the group consisting of acetals, ketals, esters, derivatives of the acetals, derivatives of the ketals, derivatives of the esters and mixtures thereof, said compound has weight average molecular weight of from 50 to 350 and is a reaction product of a hydroxy compound of 2 to 6 hydroxy groups with an aldehyde of 1 to 7 carbon atoms, or a ketone of 3 to 7 carbon atoms, or an acid of 1 to 7 carbon atoms.
A process for deicing a substrate comprising applying to said substrate a composition comprising a compound selected from the group consisting of acetals, ketals, esters, derivatives of the acetals, derivatives of the ketals, derivatives of the esters and mixtures thereof, the compound has weight average molecular weight of from 50 to 350 and is a reaction product of a hydroxy compound of 2 to 6 hydroxy groups with an aldehyde of 1 to 7 carbon atoms, or a ketone of 3 to 7 carbon atoms, or an acid of 1 to 7 carbon atoms.
