Chemical Modification Cellulose Pulp as Crude Oil Absorbent

摘要

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 TDCb. 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 1, 1533.06 cm l and 1535.82 cm l, respectively for BMC, TDC and TDCb. The order of crude oil absorptivity are TDCb > BMC > TDC.
