  • Patent number: 11352377
    Abstract: The invention relates to a process for the manufacture of organomonosilanes bearing both hydrogen and chlorine substituents at the silicon atom by subjecting a silane substrate comprising one or more silanes selected from organomonosilanes, organodisilanes and organocarbodisilanes, with the proviso that at least one of these silanes has at least one chlorine substituent at the silicon atom, to a redistribution reaction in the presence of a phosphane or amine acting as a redistribution catalyst.

  • Publication number: 20220169520
    Abstract: The invention relates to a process for the production of monosilanes of formula H4-nSiCln with n being 2, 3 or 4 comprising the step of subjecting a starting material composition comprising one or more disilanes with formula HxSi2Cl6-x containing at least one Si—H bond and optionally further silanes, in particular the side-product mixture of the Siemens Process or fractions thereof, to a reaction with a reaction-promoting agent chosen from—ether/HCI solutions—amines, phosphines, or mixtures thereof—ammonium halides, phosphonium halides, or mixtures thereof at temperatures below 200° C.

  • Patent number: 8744893
    Abstract: A method analyzes risks in a technical project for developing or manufacturing a technical system or technical components or a technical process, wherein the following steps are carried out in a risk identification process: a) provision or determination of a large number of qualitative evaluations of risks in the technical project; b) determination of a large number of quantitative evaluations of the risks; c) comparison of the qualitative and quantitative evaluations for each risk, as a result of which a comparison outcome is established for each risk; d) definition of a permissible region of comparison outcomes; e) classification of the risks that are situated outside the permissible region as unacceptable risks; f) analysis of the unacceptable risks in order to identify uncertainties in the risk analysis and further risks.

  • Publication number: 20100225661
    Abstract: In a method for computer-aided visualization of a risk status in a technical project for developing or producing a technical system, components or a process, a number of risks and/or a number of uncertainties are provided as first and/or second input variables, each risk being assigned an occurrence probability and a damage degree and each uncertainty being assigned a weighting and an estimate of damage. Furthermore, a visually distinguishable bar chart having a first and second sector for the first and second input variables is generated. For each risk, the first sector has a bar segment in which the probability-of-occurrence and the degree-of-damage variables are depicted, and for each uncertainty of the number of uncertainties, the second sector has a bar segment in which the weighting and the estimate-of-damage variable are depicted. In a circular bar chart, the corresponding bars for the risks or uncertainties are highlighted in different colors.
