摘要： A process for preparing saturated carboxylic acids having from 1 to 4 carbon atoms at a reaction temperature of from 100° C. to 400° C. and pressures of from 1.2×105 Pa to 51×105 Pa by gas phase oxidation of saturated and/or unsaturated C4-hydrocarbons, with an oxygen-containing gas and water vapor in the presence of at least one catalyst. The gas leaving the reactor is partly recirculated in a reaction gas circuit. This reaction gas circuit is configured such that part of the organic acids formed in the gas-phase oxidation is taken from the gas leaving the reactor so that the acid content of the recirculated part of the gas leaving the reactor is from 0.01% to 6.0% by volume.

摘要： A process for preparing isocyanoatoorganosilanes by thermolysis of carbamatoorganosilanes in the presence of microwave radiation, optionally employing homogeneous or heterogeneous catalysis, provides isocyanatoorganosilane product in higher yield than prior art thermolyses, and with fewer byproducts. A continuous process is thus possible.
