ALKYLBENZENE SULFONATE TYPE SURFACTANT COMPOSITION AND PRODUCTION THEREOF

摘要

PURPOSE:To produce the title water sol. compsn. which shows low viscosity even at high concn. and has superior washing power, by sulfonating an adequate mixt. of a specific alkylbenzene and a diphenylmethane or naphthalene derivative, followed by neutralization. CONSTITUTION:100 pts. wt. of an alkylbenzene having 8-18 C alkyl are mixed with 2-30 pts. wt. of a diphenylmethane derivative of formula I and/or an alkylnaphthalene of formula II. The mixt. is then sulfonated and neutralized with alkali to produce an alkylbenzene sulfonate type surfactant compsn. In formula I, each of R1-R5 is H or alkyl of CnH2n+1 (n is an integer of 0-5) and one or more out of them is alkyl of n=1. In formula II, each of R1-R4 is similar alkyl and one or more out of them is alkyl of n=1.
