This invention relates .to improved detergent" aids, more particularly to poly-alkyl phenol de-.
rivatives of strong poly-basic .mineral acids in which at least two of the 'alkyl groups contain more. thanfour carbon atoms each, and pref-- erably'between-about 5 and 8 carbon atoms each. :It has already been proposed to prepare -wetting agents and detergents by reaction of olefines, phenol, and sulfuric acid. The products obtained by such reactions contain amixture of' monoand di-alkyY-phenol derivatives, even when the 'olefines are used substantially 'in excess of jthephenols. These sulfonates are not distillable, and the separation of the product into the separate mono-alkylated and di-' or poly-alky- 'lated-components is extremely difficult, usual-.

It has now been found that detergent aids. of greatly increased efiectiveness are obtained if the poly-alkyl phenol sulfonates- 'are prepared substantially free of mono-alkyl phenol su1fo-' nates. This isespecially true with alkyl .deriva-. tives in which the alkyl groups contain from 5 to about 8 carbon'atoms, preferably 5 or 6 'carbon atoms.', I V A .i a .One suitable method 'for preparing the improved detergent aids of this invention to react the corresponding p'oly-alk'yl phenol with a. strong poly-basic mineral acid, preferably a sulfonating agent, such as strong or fuming sulfuric. acid, chloro-sulfonic acid, and .the like.
The resulting mineral acid derivatives may be used as obtained for uses in which acid detergent tion being an'even more effective wetting agent than the total salt, and the etherinsoluble fraction-beings, very'poor wetting agent.

The mixturewas thenneutralized with aqueous sodium Trydro'xide. Isopropy1 alcoholequa l to half the vol ume of the resulting mixture was added.

Other poly-.alkylphenols suitable for use in preparing the improved detergent'aids of this invention by the process described in the above eXampie are those containing 5 to 8 or'more carbon atoms in ea'ch-alkyl group. The alkyl groups may 'be normal, iso, secondary', or tertiary, or
.' even' cycli'c. Aryl derivativesof alkyl radicals are also contemplated-such. as benzyl, tolyl,
eres i, phenyl, and. the like. The poly-alkyl phenols may be obtained by alkylating a phenol with suitable alkylating agents, such as alcohols,
olefines; alkyl sulfates: and-alkyl halides, of .6 to 8 or more carbon atoms per'molecule. The alkylated phenols prepared from such olefines, or
their corresponding alcohoLsulfate, or halide derivatives, contain branched carbon chains in the alkyl group, the carbon atom attached to the 10 aromatic ring being also connected to twoor pentenes and-hexenes, or narrower cut fractions containing only isomeric olefines of the same molecular weight suchfas the pentenes, may be used. The olefinesmay also be'polymers'of low molecular weight olefines, such asdimers, trimers, tetramers, etc., of olefines of preferably less than 5 carbonatoms per molecule, particularly of isobutylene. f The alkyl phenols. may be prepared by any suitable method such as the: methods described inU. S. Patents Nos. 1,954,985 and 2,045,749 'using preferably a large proportion of olefines v to phenols. The products obtained by such methads will contain mixtures of mono.-, di-, and possibly higher poly-alkyl phenols.

such as the crude phenol or cresol fractions obtained as coal-tar distillate 'fractions;'- the petroleurn phenols such as the phenolic compounds extracted from petroleum crudes and distillate 'fractions thereof by alcoholic alkali; also monoandpoly-hydroxy derivatives of poly-nuclei hydrocarbons, such as alpha and betanaphthol or aryl substituted phenols. The petroleum phenols mentioned above are preferably obtained from 50 kerosene and'gas oil distillates. They may be extracted with alcoholic sodium hydroxide.

As sulfonating agents, strong sulfuric acid (of to concentration), fuming sulfuric acid,
or liquid sulfur trioxide, may bejused. Care 5 should be taken not to use the stronger agents under such conditions as to affect the alkyl- For example, fumingacids are preferablyavoided in sulfonating poly-alkyl phenols of which thealkyl groups are oleflne polymers or 1 contain long or highly branched carbon chains. Although sulfuric acid is preferred, it is possible to use other strong poly-basic mineral acids, such as phosphoric acid. Poly-alkyl phenol' phos phates may also be prepared by reaction of the 15 poly-alkyl phenol with phosphorous tri-chloride or with phosphorous oxy-chloride, followed by suitable hydrolysis to prepare the phosphoric acid derivative. Such phosphoric acids and their salts are used asdetergent' aids preferably in 20 neutral'or hardwater, in which they are very effective,
Although the exact limitations-of the various factors involved in the preparation of detergent aids according to the present invention are not 25 known with absolute certainty, the following ranges and preferred conditions are believed to be sufficiently definite to guide those skilled in the art in carrying out this invention. The strength of the sulfuric acid to be used should 30 be between 85% H2504 and 20% oleum (fuming acid), and the stronger the acid the lower should be the temperature at which it is used, although generally, satisfactory. results are obtained by using the ordinary concentrated sulfuric acid 3 (95% H2804) at a temperature between 70 F. and F. 'With stronger acid, the temperature may be lowered to 32 F. or even 15 or -5 F., using inert diluent, such as a straight run or The con- 40 ditions of the reactions should be preferably maintained so as to produce primarily monoalkali metal sulfonates and preferably no disulfonates.
' Proportions of the primary reactants, i. e.', the 45 alkyl phenols and the sulfuric acid, may be varied considerably, but ordinarily the ratio of sulfuric acid to phenol shouldbe between the approximate limits of3 to 1 andlto 1. The acid serves both as a reagent and a dehydrating agent, hence the 50 stronger acids are used in smaller proportions. The time'of contact will, of course, vary inversely with the temperature and concentration of acid, but ordinarily will be between the approximate limits of 10 minutes and 1 or 2 hours. Extremely 55 short times of contact, e. g., substantially less than 1 minute, may be used with relatively concentrated sulfuric acid and at relatively elevated temperature.
