Ethanedial, Oxalaldehyde

Appearance

Pale yellow to colorless liquid

Description

Is used as a solubilizer and cross-linking agent in polymer chemistry for: proteins (leather tanning process), collagen, cellulose derivatives (textiles), hydrocolloids, and starch (paper coatings).

Function

Coated paper and textile finishes use large amounts of glyoxal as a crosslinker for starch-based formulations. It condenses with urea to afford 4,5-dihydroxy-2-imidazolidinone, which further reacts with formaldehyde to give the bis(hydroxymethyl) derivative used for wrinkle-resistant chemical treatments.
