630 REPORT— 1894. 



A large quantity of the crude clilorination product was digested with acetate. 

 From the result several bodies have been separated by fractional distillation, a 

 comparatively easy process, since the acetates are much more stable than the 

 chlorides. 



A fraction at 322° 0. gave 72-61 C and 4-28 H. Therefore nearly pure diacetate. 



We have some proof that a chlormonacetate is also formed as well as soma 

 chlorinated diacetates. Of these we have isolated one product, which on analvsis 

 gives (I) 11-01 per cent. CI; (II) 11-4 per cent. CI: CisH.Cl.^CaHjOJ.j requires 

 11-2 per cent. CI. It melts at about 60° C. 



Acenaphtene diacetate distils at about 290° 0. and melts at 46°. 



We are obtaining larger quantities of these acetates — fluorene, acenaphtene, and 

 dibenzyl — in order to study them further.
