    Abstract: The direct dosing of aqueous solutions with acrolein as a microbiocide is problematic because of the associated laborious safety measures and the hitherto known use of reaction mixtures from the deacetalisation has proven not to be very economical. … According to the invention, aqueous solutions can be dosed in a simple, safe and economical manner with acrolein at a sufficient concentration level to be active as a biocide by cleaving acrolein acetals in the aqueous phase in the presence of a strongly acid deacetalisation catalyst into acrolein and the alcohol component, continuously removing the resulting acrolein from the deacetalisation mixture and transferring the acrolein into the aqueous solution to be dosed using an inert gas stream or a liquid jet pump with the aqueous solution to be dosed as the jet liquid.

    Abstract: Calcium formate is produced in aqueous phase by reaction of calcium hydroxide with formaldehyde in the presence of hydrogen peroxide or by reaction of calcium peroxide with formaldehyde. The molar ratio of CaO or Ca(OH)2 to H2CO to H2O2 is 1 to 2 to 1-1.2 and the molar ratio of CaO2 to H2CO is 1 to 2. Calcium formate is obtained in an almost substantially quantitative yield and in highly pure form. The process avoids the disadvantages of prior processes for the production of calcium formate from calcium hydroxide and formaldehyde.
