ABSTRACT:
A chemical composition is disclosed herein for performing a rapid neutralization of formaldehyde vapors, control of incidental releases, detoxification and disposal of spent or unused aqueous and/or non-aqueous formaldehyde solutions, and feasible conversion of the waste formaldehyde into a coarse pharmaceutical product.
The composition is consisting essentially of an alkanolamine for rapid reaction with formaldehyde vapors, with formaldehyde in aqueous and/or non-aqueous solutions and for optimizing the reactions; a coumarin metabolite for neutralizing formaldehyde in concentrated aqueous solutions; urea for forming an inclusion/addition compound with formaldehyde, and; beta cyclodextrin for inclusion complexation of the methanol and methylene glycol in inhibited formaldehyde solutions.
