Formaldehyde in the form of urea-formaldehyde concentrate (UFC) is used as an additive in the manufacture of solid urea. Johnson Matthey’s skills in catalyst design, along with ammonia, methanol and formaldehyde process technology development have been used to create a new and cost effective integrated method (iUFC) of synthesising small quantities of UFC (up to 85 wt% urea-formaldehyde) which allows a urea producer to make significant savings when compared to the alternative of open market purchases.
