Abstract
296,008. Kalle & Co., Akt.-Ges, Aug. 22, 1927, [Convention date]. Diazo compounds. - Hydrofluoborate of 1- diazo-4-dimethylaminobenzene is prepared by diazotizing 1-amino-4-dimethylaminobenzene in the presence of liydrofluoboric acid. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the diazo! compound obtained by diazotizing 1-amino-4-phenylaminobenzene in a solution of hydrochloric acid. This subject-matter does not appear in the Specification as accepted.
