The kinetic parameters of the complex reaction between phenol and formaldehyde in the presence of sodium hydroxide (NaOH) have been obtained by differential scanning calorimetry (DSC). The two dominant reactions appear to be addition of formaldehyde to phenol with formation of o-hydroxymethyl-phenol

A flow-injection system is proposed for the rapid determination of trace amounts of formaldehyde based on its inhibition of the Brilliant Green-suiphite reaction at pI1 7. Formaldehyde in the range 40-3000 ng ml-' can be determined at a rate of 35 f 5 samples h -I. The limit of detection was 20 ng m
