The solutions from the above determinations of neutralization equivalent were evaporated to a small volume on the steam-bath, diluted to 25 cc. with water, filtered and acidified with 0.05 N hydrochloric acid. The precipitate was filtered on a hardened paper and washed with hot water until free of chlorides. After drying it melted at 234-236°a nd analysis showed it to be free of acetic acid.
