  • Patent number: 10609931
    Abstract: The present invention relates to mixed crystals comprising a) leavening agent and b) 0.1 to 5000 ppm by weight of crystallization aid, based on the total amount of the leavening agent, in the form of at least polymer, wherein when hydrophilic cellulose derivatives are used as crystallization aid, the amount thereof is reduced to less than 100 ppm by weight, based on the total amount of the leavening agent. The present invention further relates to the production of the mixed crystals and to the use thereof in the production of bakery products, as acid regulator in foods, in the production of cosmetics products, in the synthesis and formulation of pharmaceutical products, and also as blowing agent in industrial processes such as, for example, the production of foam rubber, or for fire-extinguishing formulations. The present invention relates, furthermore, to the production of bakery products.

  • Patent number: 7907283
    Abstract: The invention relates to a process for determining the total oxygen content and the total carbon content in ammonia, in which ammonia is first split into nitrogen and hydrogen, then the oxygen still present in the ammonia is reacted essentially fully with hydrogen to give water and the carbon still present is reacted essentially fully with hydrogen to give methane. In a next step, the water content and the methane content in the gas are determined. Finally, the total oxygen content is determined from the water content and the total carbon content from the methane content. The invention further relates to an apparatus for performing the process, which comprises a cracker for splitting the ammonia and for converting the oxygen- and/or carbon-comprising compounds, and at least one cavity ring-down spectrometer for detecting the water content and/or carbon content.
