Abstract:  Dioxan suspension is a suitable reaction medium for heterogeneous alkyla­tion of bead, powdery, and fibrous types of cellulose with chloromethyloxirane under catalysis of perchloric acid. The prepared 0-(3-chloro-2-hydroxypropyl)celIuIose was quantitatively converted to 0-(3-iodo-2-hydroxypropyl)-cellulose by treatment with sodium iodide in 2,4-pentariedione or acetone.
