Non-catalytic reaction of hydroxymethylation has been studied. It has become clear that its reaction concern<SUB>i</SUB>ng formaldehyde may be described as a pseudo first order reaction. The effective rate constant of the reaction concerning formaldehyde (K<SUB>ef</SUB>) has a simple mathematical relation to ratios of its components. At the smaller molar ratios, the effective rate constant is expressed by the following equation : <BR>K<SUB>ef</SUB> = K (n<SUB>o</SUB>- K<SUB>a</SUB>) (m<SUB>o</SUB> -K'<SUB>a</SUB>) = Knm= Kp where K-characteristic rate constant of the system <BR>Ka, K'a-constants n<SUB>o</SUB>= [L] <SUB>0</SUB>/ [A] <SUB>0</SUB>, m<SUB>o</SUB>= [S] <SUB>0</SUB>/ [L] <SUB>0</SUB>, P<SUB>o</SUB>= [S] <SUB>0</SUB>/ [A] <SUB>0</SUB><BR>A-formaldehyde <BR>S-component, subjected to hydroxymethylation (substrate) <BR>L-solvent <BR>[X] <SUB>0</SUB>-initial concentration of component X<BR>In the present work, starting from the equation (1) and applying the molar ratio method to the concentrated systems, a method for the determination of the actual concentration of formaldehyde and substrate participating in the hydroxymethylation reaction, immediately according to the data given by the study of kinetics of hydroxmethylaion reaction, has been introduced.
