Description
United States Patent SULFONATE DETERGENT. BLEND Frederick Neil Bauingaitner, (Iranfor-d, N. 3., assignor to Essa Research and Engineering (Iernpany, a corporation of Delaware No Drawing. Application March 31, 195%), Serial No. 153,309
8 Claims. (Ci. 2521o1) The invention relates to a novel detergent composition. More particularly the invention is concerned with a detergent comprising as active ingredients a blend of alkyl aryl sulfonates.
Alkyl aryl sulfonates prepared by the alkylation of an aromatic nucleus with branched-chain olefins (such as obtained by polymerizing low molecular weight olefins, e. g. propylene) and subsequent sultonation of the alkylate are now established as good detergents for general purposes. However, these compounds possess only mediocre detersivc properties at low concentrations (less than 0.25%
It is the purpose of this invention to prepare a detergent having good detersive properties at low concentrations.
It is also an object of this invention to modify the detersive activity of a branched-chain alkyl aryl sulfonate to confer upon it good detersive properties at low concentrations.
It has been found that a superior detergent is prepared by blendin a detergent sulfonate of the type:
where R is a branched-chain alkyl radical of 9 to 18 carbon atoms and M is an alkali metal with 2.5 to 50 weight per cent or preferably, 5 to 50 Weight per cent, based on the total sulfonate blend, of a straight-chain secondary alkyl aryl sulfonate of the formula:
where R is a straight-chain alkyl radical of l5 carbon atoms, R" is a straight-chain alkyl radical of 8-14 carbon atoms Where the sum of R and R" is 9-15, and M is an alkali metal. The detersive power of the resulting blend of sulfonates is substantially superior at low concentrations (up to 0.25 grn./ 100 ml.) to that of the branchedchain detergent or the straight-chain detergent alone, and greater than the additive effect of both compounds.
Launder-Oineter data on the synergistic effect of typical blends are given in Table I. in the table data are given for a typical dodecylbenzene suifonate prepared by alkylating benzene with a Gig-branched olefin (prepared by polymerizing propylene) and thereafter sulronating the alkylate and neutralizing, as indicated by compound D. The presence of weight per cent of a straight-chain secondary alkyl aryl sulfonate, compositions E, F, G, H, etc., in a blend with 75 weight per cent of D produces an unexpectedly large rise in detergency over that of D at concentrations below 3.2 gm./ 100 ml. At the same time the presence of these substances does not materially alter the detersive power of D at higher concentrations. It is also to be noted that blends of D with a branched-chain secondary alkyl aryl sulfonate possess no advantage over D alone and are exceedingly poor in hard waters (Blend N, Table I).
