Abstract
23,190. Bosnische Electricitaets Akt.- Ges. Jan. 17, [Convention date]. Acetic anhydride is obtained by heating ethylidene diacetate above its boiling-point, or by heating it with catalysts. The catalysts specified are sulphuric acid or mercuric sulphate. Acetaldehyde is obtained as by-product in the above process. The Specification as open to inspection under Section 91 (3) (a) also specifies potassium bisulphate as a catalyst in the process: this subjectmatter does not appear in the Specification as accepted.
