ABSTRACT:
2-Alkylidene-1,3-dioxolanes and 2-(1-alkylalkylidene)-1,3-dioxolanes are employed as acid acceptors in methylchloroform, trichloroethylene or mixtures thereof. The preferred acid acceptor is 2-methylene-1,3-dioxolane.
In another aspect of the invention, aliphatic aldehyde hydrazone is employed to stabilize 2-alkylidene-1,3-dioxolane and 2-(1-alkylalkylidene)-1,3-dioxolane. The preferred aliphatic aldehyde hydrazone is acetaldehyde dimethylhydrazone.
