1,3-bis(hydroxymethyl)-5,5-dimethylimidazolidine-2,4-dione

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: In a further embodiment (the post addition method), an aqueous solution of dimethyloldimethylhydantoin, monomethyloldimethylhydantoin, and dimethylhydantoin is produced by admixing (a) from about 80 to about 90% by weight of an aqueous solution of methylolated dimethylhydantoins having greater than 0.1% by weight of free formaldehyde with (b) about 20 to about 10% by weight of dimethylhydantoin based upon 100% by weight of aqueous solution of methylolated dimethylhydantoins and dimethylhydantoin combined.

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: DMDMH is a formaldehyde donor which is the diformylated product of DMH and formaldehyde. MDMH is first formed as an intermediate. MDMH, itself, is a formaldehyde scavenger containing about 19% by weight of bound, but available, formaldehyde. Subsequent reaction of MDMH with formaldehyde yields DMDMH which theoretically contains 31.9% of bound but available, formaldehyde.

実験手順: An aqueous DMDMH/MDMH/DMH solution was prepared by adding 17.5 parts of DMH to 85 parts of a concentrated DMDMH solution having 20.7% by weight total formaldehyde and 1.2% by weight free formaldehyde.
