ACETO ACETIC ESTER 79 



alcoholic solution of sodium ethoxid on monochlor-ethyl and mono- 

 chlor methyl-acetoacetic esters and are decomposed by alcoholic soda 

 into ethoxy-ethyl acetone, (C^ H5 O) CH, CO CHj (C2 H5), and ethoxy- 

 methyl acetone, (C^ H5 O) CH^ CO CH^ (C H3), which boil at 112° to 

 115° and 100° to 105° respectiveh'.
