cupriethylenediamine hydroxide
A solution of cupric hydroxide in aqueous
ethylenediamine (Cu(OH) 2 + xNH
2 CH 2 CH 2 NH
2 → ([NH 2 CH
2 CH 2 NH 2 ]
2 Cu(OH) 2 ). The solution
will dissolve cellulose when the concentration of
copper and ethylenediamine are within certain
limits. The VISCOSITY
(2) of a cellulosic solution in
cupriethylenediamine is used in quality control in
the manufacture of paper. (17 )
