Glyoxal hydroxymethyl

Glyoxal Resins. Since the late 1960s, glyoxal resins have dorninated the textile-finish market for use as wrinMe-recovery, wash-and-wear, and durable-press agents. These resins are based on l,3-bis(hydroxymethyl)-4,5-dihydroxy-2-imidazohdinone, commonly called... [Pg.330]

The glyoxals, of which (hydroxymethyl) glyoxal is sometimes regarded as the simplest osone, differ from the osones in many of their properties and are not considered in this review. [Pg.45]

The chemical name of this reagent is l,3-bis(hydroxymethyl)-4,5-dihydroxy-imidazolidinone-2 but it is usually called DMDHEU or the glyoxal reactant because it is prepared from glyoxal, urea, and formaldehyde. Other methylolamide agents that have been used for producing wrinkle resistance in cotton include the aforementioned urea formaldehyde, dimethylolurea, dimethylolethyleneurea, and formaldehyde adducts of melamines (triazines), acetylenediurea, propyleneurea, uron, triazones, and alkyl carbamates. Reactions between methylolamides and cellulose occur in the presence of acid (or Lewis acid) catalysts and are very fast at elevated temperatures—sufficiently so that they are adaptable to the requirements of rapid, commercial processing of cotton fabrics. [Pg.88]

Die intramolekulare Cannizzaro-Reaktion wird u.a. beobachtet bei Hydroxy-aldehyden (z. B. 3-Hydroxy-propansaure aus Glycerinaldehyd), a-Oxo-aldehyden (z.B. Phenyl-glykolsdure aus Phenyl-glyoxal), ver-schiedenen Dialdehyden (z. B. 4-Hydroxymethyl-benzoesiiure aus Terephthaldialdehyd510) oder ot-Oxo-ace-talen511. [Pg.274]
