With a total of 2 patents to his name, Busse's work has had a meaningful impact on the industry.

Latest Patents

Busse's latest patents include a process for the preparation of 1,5-dihydroxynaphthalene. This innovative method involves the alkaline pressure hydrolysis of the disodium salt of naphthalene-1,5-disulphonic acid at temperatures ranging from 270°C to 290°C and under pressures of 14 to 20 bar. The process utilizes an excess of sodium hydroxide solution, ensuring a molar ratio of NaOH to disodium salt of at least 12:1. The resulting 1,5-dihydroxynaphthalene is then aminated with ammonia in the presence of ammonium bisulphite to produce 1,5-diaminonaphthalene. This method allows for a significant increase in purity, achievable by adjusting the molar ratio of ammonia to 1,5-dihydroxynaphthalene to at least 6:1.

Another patent focuses on the preparation of chemical compounds obtained as solids. This process involves spraying liquid starting substances from separate nozzles, allowing them to mix and react in overlapping spray cones, resulting in solid chemical compounds.
