Definitions

• This invention relates to new compositions having detergent properties. More particularly, it pertains to compositions containing synthetic sulfated and sulfonated organic detergents of certain specific types in controlled proporations which have an-exceptionally lvaluable combination of properties.
• a special object of the invention is the provision of mixtures of alkyl aryl sulfonate detergents and alkyl su1 fate salt detergents which not only have an especially advantageous combination of desirable surface-active properties but also form concentrated solutions in water which are stable to precipitation and gelling at low temperatures and so are eminently adapted for use as liquid detergent compositions. Because of the special advantages of the new detergent mixtures in solutions suitable for sale in the rapidly increasing market for liquid household detergents, for instance,this form of the newcompositions will be emphasized in the following description of the invention, but it will be understood that the new detergent mixtures are not restricted to such use and can be advantageously employed as solid products in powder, flake, bar or other conventional forms.
• This cold stability is conveniently measured by clear point determinations, the clear point being the temperature, expressed in degrees centigrade, at which a turbid aqueous solution of the detergent mixture of given concentration clarifies during gradual heating.
• the detergent mixtures of the invention having these advantageous properties are mixtures of alkyl aryl sulfonates having 8 and/or 9 carbon atoms in the alkyl groups, preferably together with one or morealkyl aryl sulfonates vw'th 10, ll, 12 or 13 carbon atoms in the alkyl groups and substantially free from alkyl aryl sulfonates comprising less than 8 or more than 13 carbon atoms in the alkyl groups in admixture with mixtures substan- States Patent 0 'stantial amount in such component.

• alkyl aryl sulfonate mixtures with alkyl groups comprising 10 and 11, or 10, 1i and 12, or 1.0, 11, 12 and 13, or 11, 12 and 13, etc., carbon atoms are suitable for use in the present mixtures in addition to the essential C and/or C -alkyl aryl sulfonates.
• mixtures of alkyl aryl sulfonates in which the number of carbon atoms in the alkyl groups do not form successive series,and thus, for example, comprise 10 and 12, 10 and 13, 10, 11 and 13 or 11 and 13 carbon atoms, may likewise be used with the C and/or C -alkyl aryl sulfonates with good results.
• Alkyl aryl sulfonates which are particularly suitable for use in the process according to the invention may be prepared by alkylation of benzene or naphthalene, or substitution products thereof such as toluene, methyl naphthalene, etc., using HF or H as alkylation catalyst, with an olefin mixture obtained by the vapor-phase cracking of 'paratiin waxes or by cracking by solvent extraction refined catalystically cracked heavy oil, or by polymerization of alkenes such as propene as used for the preparation of propylene tetramers.
• the olefins used are those having the number of carbon atoms required to give the above indicated alkyl groups.
• the alkylate is sulfonated and neutralized in] the customary way.
• the alkyl sulfates chosen are preferably watersoluble secondary alkyl sulfate salt detergents prepared via sulfation of a mixture substantially consisting of C or C to C olefins obtained in one of the two ways just described.
• mixtures of compounds to be used for the alkylation and the preparaton of alkyl sulfates will be obtained by distilling mixtures which, in addition, contain compounds with more and/or fewer 's,000,saa
• ixture of this type is also referred to here as a C or C olefin mixture and the sulfate prepared there- 1 as a C or C to C alkyl sulfate.
• the alkyl aryl sulfonates so that, example, an alkyl aryl sulfonate mixture referred to he term C or C to C may also contain a small entage of C and C alkyl aryl sulfonates.
• he preferred alkyl aryl sulfonates are the waterble monoalkylbenzene monosulfonic acid salts, pararly the alkali metal, for instance potassium, or amium or amine salts.
• Similar salts are preferred in ing the C or C to C alkyl sulfate salt detergent ponent of the new mixtures.
• These alkyl sulfate are advantageously mixtures predominating in ght or substantially straight chain 2-alkylsulfate salts. greatest improvements in foaming, wetting properties clear point have been obtained by use of ternary rgent mixtures of the previously described polyethylglycol with alkylphenol monoethers with C -C lbenzencmonosodium sulfonates and C -C secondrlkyl sodium sulfates.
• alkylphenol-polyethylene glycol monor which should be present with the indicated alkyl sulfonate and alkyl sulfate salt detergent mixtures reparing the preferred compositions of the invention depend upon the properties desired in the final prod- Even relatively small amounts of the specified lphenolpolyethylene glycol monoethers in the new positions give marked improvements in the wetting foaming properties as well as in the clear point of alkylbenzene sulfonate-secondary alkyl sulfate salt rgent mixtures.
• the wetting and foamiroperties of the mixture increase.
• the proportions of the three detergent ionents are 30% C -C alkylbenzene sodium sulzes, 50% C -C secondary alkyl sodium sulfate and octylphenol polyethylene glycol monoether with i ethylene glycol units
• the relative wetting and foamalues are 200 and 160, respec- I, and the clear point is below 0 C. even in soluof 34% concentration.
• the alkyl sulfate salts are preferably formed by adding the corresponding olefins to the alkyl aryl hydrocarbon sulfonation product andcarrying out sulfation of the olefins with excess sulfonatmgagent present therein.
• the sulfonation 15 carried out with oleum of, for example, 20% free S0 concentration using a mole ratio of S0 to alkyl aryl hydrocarbon of about 5 to 7:1.
• the alkyl aryl sulfonic acids and alkyl sulfuric acids can be separately prepared and mixed together 1B the required ratio, after which the mixture is neutralized and extracted preferably with a liquid hydrocarbon such as gasoline to remove unconverted organic material and/ or other undesirable impurities.
• the alkyl aryl sulfonate and alkyl sulfate salt detergents employed in the new compositions will usually contain a. certain amount of inorganic salt, particularly the sulfate corresponding to the base used in the neutralization step in their preparation. It may be desirable to add other builders such as phosphates, silicates, carbonates, foam stabilizers, washing promoters, bleaching agents, and the like, depending upon the intended use of the products.
• the new compositions can also be used in admixture with other detergents. When the compositions are to be used in solution, for instance sold as liquid detergents, it is desirable that the inorganic salt content be below about 25% and more advantageously not greater than about 15%.

• alkyl sulfate salt detergent and alkylphenol polyethylene glycol monoethers in such cases is preferably between about 10% and about 50%. more preferably about 20% to about 40% by weight of the solution.
• EXAMPLEII Benzene was alkylated in a stirred reactor with a C. to C olefin mixture obtained by vapor phase cracking of a catalytically cracked refined heavy hydrocarbon oil.
• the alkylation was started with a mixing ratio of benzene to olefins of 10:1.
• Hydrogen fluoride was used as catalyst, care being taken to ensure a phase ratio of the total quantity of hydrocarbons to hydrogen fluoride of 1:1 by volume.

• the mixture thus obtained was neutralized with a caustic soda solution and saponiiied in order to convert the dialkyl sulfates present into monoalkyl sulfates. After adding 25% by weight of isopropyl alcohol liquid phase desalting was then carried out. An extraction was then carried out with gasoline as a result of which unconverted organic material was removed. Finally, the solution was boiled down until the desired concentration was obtained.
