Abstract

Benzyl cellulose is purified by extraction with hot or boiling ethyl alcohol or other lower alcohol, for example, boiling industrial spirit. The purification may be carried out during manufacture at the final washing stage; or the benzyl cellulose after manufacture may be reduced to a fine powder, and then extracted. By the extraction, resinous products produced during benzylation are removed, and articles made from the purified product, such as dental plates, have a greater resistance to water and do not develop opacity under moist conditions. Specification 327,714, [Class 2 (ii)], is referred to.
