Abstract A surface active compound, useful for level dyeing hydrophobic synthetic fibers such as polyester fibers with disperse dyes, said surface active compounds having the formula WHEREIN S represents an alkyl group having 1 to 22 carbon atoms, T represents an alkyl group having 1 to 22 carbon atoms, N IS AN INTEGER OF 0 TO 4; X represents an alkylene group having 2 to 6 carbon atoms; Y represents -O- or R1 and R2 each represents a hydrogen atom or an alkyl group having 1 to 22 carbon atoms but one of R1 and R2 should be the alkyl group if the other is the hydrogen atom; Z1, Z2, Z3 and Z4 each represents a hydrogen atom or -SO3M wherein M represents an alkali metal atom or an organic amine residue, at least one of Z1, Z2, Z3 and Z4 is -SO3M; and l1, l2, l3, l4, m1, m2, m3, m4, m5 and m6 are a positive integer satisfying the following relationship:
A SURFACE-ACTIVE COMPOUND PRODUCED BY REACTING ETHYLENE DIAMINE AND PROLYLENE OXIDE AT A TEMPERATURE OF 100* TO 120*C, TO OBTAIN A REACTION PRODUCT COMPRISING TETRA-POLYOXYPROPYLENE ETHYLENE DIAMINE, TREATING SAID DIAMINE WITH POTASSIUM HYDROXIDE AND ADDING THERETO EHTYLENE OXIDE AT A TEMPERATURE OF ABOUT 190* TO 200*C TO OBTAIN AN INTERMEDIATE PRODUCT, SULFONATING SAID INTERMEDIATE PRODUCT WITH CHLOROSULFONIC ACID AT A TEMPERATURE RANGING BETWEEN ABOUT 20* AND 35*C, AND NEUTRALIZING THE REACTION MIXTURE WITH AQUEOUS SODIUM HYDROXIDE TO OBTAIN THE DESIRED SURFACE-ACTIVE COMPOUND HAVING 10 OXYPROPYLENE GROUPS AND 60 OXYETHYLENE GROUPS.
