Recentry, utilization of deinked pulp increases extremely and deinking agent is becoming important. Alkenyl succinic acid base surface active agents were synthesized to evaluate their performance in the deinking of waste newsprint. The results are summarized as follows. (1) The surface active agents made by the addition of ethylene oxide to alkenyl succinic acid monoalkyl ester showed best deinking performance. (2) The optimum carbon number of alkenyl group in alkenyl succinic acid was 16 or 18. (3) EO mole number, in the range of 9 to 22, did not have much influence on deinking performance. (4) The optimum carbon number of alkyl group was 13.
