Ss. Arslanov et al., INFLUENCE OF CELLULOSE ACTIVATION ON ITS HETEROGENETOUS SOLID-PHASE REACTIONS WITH AN ORTHOPHOSPHORIC ACID-UREA MIXTURE, Russian journal of applied chemistry, 68(3), 1995, pp. 444-447
A study has been made of cellulose activation with sodium hydroxide an
d liquid ammonia prior to esterification with an orthophosphoric acid-
urea mixture with the aim of preparing products suitable for separatio
n and purification of proteins.
