The increasing demand for explosives during World War I exceeded the ammonia production capacities of the Oppau works of BASF, who owned the patents for the Haber process. Leuna in central Germany, out of range of French aircraft, was selected as the location of a second plant [3] named Badische Anilin- und Sodafabrik, Ammoniakwerk Merseburg ...
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
The production of butanol by biological means was first performed by Louis Pasteur in 1861. [5] In 1905, Austrian biochemist Franz Schardinger found that acetone could similarly be produced. [ 5 ] In 1910 Auguste Fernbach (1860–1939) developed a bacterial fermentation process using potato starch as a feedstock in the production of butanol.
Urea plant using ammonium carbamate briquettes, Fixed Nitrogen Research Laboratory, ca. 1930 Carl Bosch, 1927. The Bosch–Meiser process is an industrial process, which was patented in 1922 [1] and named after its discoverers, the German chemists Carl Bosch and Wilhelm Meiser [2] for the large-scale manufacturing of urea, a valuable nitrogenous chemical.
In order to make Germany independent from the importation of natural rubber, the first industrial plant for the production of artificial rubber was built in Schkopau near Halle (Saale) and named Buna-Werke GmbH Schkopau. It was a subsidiary of Ammoniakwerk Merseburg GmbH, later known as Leunawerke, which belonged to IG Farben. The foundation ...
Cyclohexanone ((CH 2) 5 CO), a symmetrical cyclic ketone, is an important intermediate in the production of nylon. Isophorone, derived from acetone, is an unsaturated, asymmetrical ketone that is the precursor to other polymers. Muscone, 3-methylpentadecanone, is an animal pheromone. Another cyclic ketone is cyclobutanone, having the formula ...
Most of the worldwide production of phenol and acetone is now based on this method. In 2022, nearly 10.8 million tonnes of phenol was produced by the cumene process. [4] In order for this process to be economical, there must also be demand for the acetone by-product as well as the phenol. [5]
Acetone and acetic anhydride ((CH 3 C(O)) 2 O) upon the addition of boron trifluoride (BF 3) catalyst: [11] (CH 3 C(O)) 2 O + CH 3 C(O)CH 3 → CH 3 C(O)CH 2 C(O)CH 3 A second synthesis involves the base-catalyzed condensation (e.g., by sodium ethoxide CH 3 CH 2 O − Na + ) of acetone and ethyl acetate , followed by acidification of the sodium ...
