摘要： The invention relates to a method for producing vicinal diols or polyols from an organic reaction mixture containing formic acid esters of vicinal diols or polyols. The reaction mixture is treated with water without adding bases and thermally treated afterwards, whereby the formic acid esters are hydrolyzed, the aqueous formic acid is separated and the vicinal diols or polyols remain.

摘要： The invention relates to a method for removing sulphur dioxide from a dry gas stream which comprises the following steps: (a) admixing a liquid comprising hydrogen peroxide into the gas stream, where sulphuric acid forms from the hydrogen peroxide and the sulphur dioxide, and (b) condensing, absorbing or aerosol-precipitating the sulphuric acid formed. The admixed liquid comprising hydrogen peroxide is mixed with the dry gas stream in less than 0.3 s so that the admixed liquid is essentially homogeneously distributed in the gas stream. In addition, the invention relates to a device for removing sulphur dioxide from a dry gas stream which comprises at least one atomizer nozzle for adding the liquid comprising hydrogen peroxide and a filter or aerosol precipitator arranged in the direction of flow of the gas stream behind the at least one atomizer nozzle, where in each case at least one atomizer nozzle is arranged on a cross sectional area of from 300 to 350 cm2.

摘要： A method is proposed for producing sulfuric acid, according to which process gases, which contain sulfur dioxide, are obtained by combusting liquid sulfur with process air, which is supplied from the outside, or by cleaving waste sulfuric acids, and the sulfur dioxide from the sulfurous process gases is oxidized to form sulfur trioxide and is converted into sulfuric acid according to the contact method, characterized in that the process air, which is supplied from the outside for the combustion of sulfur, or the process gases containing sulfur dioxide, which are obtained by cleaving waste sulfuric acid, are reduced with respect to the water vapor content thereof, in that they are cooled.
