Abstract

The extractant mixture contains 10-95% methylethyl ketone and extraction is effected at ordinary temps. and generally under atmos. press. For acrylic acid extraction the methylethyl ketone concn. is is not 42% and is pref. 55-95%, for methacrylic acid extraction, the methylethyl ketone concn. is not less than 10 %, and is pref.
