  • PROCESS FOR THE PREPARATION OF AQUEOUS FORMALDEHYDE SOLUTIONS
    Publication number: 20100137450
    Abstract: Aqueous formaldehyde solutions are prepared and the formaldehyde content of the aqueous formaldehyde solutions produced is determined by an online analytical method. The desired formaldehyde content can subsequently be established by addition of water so that an aqueous formaldehyde solution having a defined formaldehyde content (formalin) is obtained.
