    Abstract: The crude oil absorption behaviour of chemically modified celluloses was investigated. The result showed that only three out of eleven modified celluloses are effective as crude oil absorbents; benzoyl modified cellulose BMC, toluene diisocyanate cellulose TDC, toluenediisocyanate cellulose blown TDC<SUP>b</SUP>. These three crude oil absorbents posses the same functional group; the carbonyl. The IR of these three cellulose absorbents showed the presence of carbonyl group 1425.51 cm <SUP>1</SUP>, 1533.06 cm <SUP>l</SUP> and 1535.82 cm <SUP>l</SUP>, respectively for BMC, TDC and TDC<SUP>b</SUP>. The order of crude oil absorptivity are TDC<SUP>b</SUP> &gt; BMC &gt; TDC.
