Residual formaldehyde in steam-formaldehyde sterilized materials
Biomaterials, 1986The amounts of residual formaldehyde and paraformaldehyde present in polymeric materials after steam-formaldehyde sterilization in a commercial sterilizer were determined. Appreciable amounts of residue were detected in ethylene-vinyl alcohol copolymer (EVOH), polyamide-6 (PA-6) and natural rubber (NR).

A method is described for the analysis of three permanent finishes based on formaldehyde. The finish is hydrolysed by 12N sulphuric acid, without heating, and the yield of formaldehyde is assessed colorimetrically by means of the reaction with chromotropic acid.

Urea–Formaldehyde and Melamine–Formaldehyde Polymers
1989According to Meyer1 the history of urea–formaldehyde (UF) resins can be divided into five different periods: (i) Synthesis of the raw materials urea and formaldehyde. This period started with the synthesis of urea by Wohler in 1824. Formaldehyde was first recognized by Butlerov in 1859 when attempting to synthesize methanediol.
