Systematic Qualitative Organic Microanalysis

Review of Organic Microchemistry

“…Dadieu and Kopper (75) in a review of micropreparative methods in organic chemistry include a description of apparatus from the unpublished work of O. Kermauner: (1) for the micropreparation by a bomb reaction of C2D2 + DBr(AlBr3 catalyst) / CD3CDBr2; (2) for reaction of gases in liquids, as, for example, the use of deuteroacetylene and deuterosulfuric acid in the preparation of deuteroacetaldehyde; also (3) an apparatus with a special circulating pump for the catalytic hydrogenation of acetylene to ethylene, using a colloidal palladium solution as the catalyst which is shown in Figure 3. The initial volume of the mixture of acetylene and hydrogen was 500 ml.…”
