2 Claims, No Drawings UNSATURATED ZWITTERIONIC SURFACE ACTIVE COMPOSITION This is a division of application Ser. No. 024,330, filed Mar. 31, 1970, now U.S. Pat. No. 3,668,240.
BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to zwitterionic surface active compounds which are useful as detergents. The zwitterionic surface active compounds are characterized by having an unsaturated double bond located in the molecule between the anionic and cationic groups.
2. Prior Art Zwitterionic or internally neutralized surface active compounds having both anionic and cationic groups are known. They are usually depicted as having a formula R,R R N R X' in which the Rs are alkyl or alkylene groups (R. always being saturated aliphatic) and X is COO" or 80 No previous disclosure has been found of a surface active compound having R representing a group CH CH=CH CH It is this unique molecular arrangement which distinguishes the compounds of the present invention from prior art zwitterionic surface active compounds. It has been surprisingly discovered that the I presence of the double bond contributes unexpectedly to the detergent properties of this molecule. SUMMARY OF THE INVENTION The compounds of the present invention have the formula in which R represents an unsaturated or saturated aliphatic group having six to 24 carbon atoms, preferably a saturated group having eight to 18 carbon atoms, R and R each represent an alkyl group having one to six carbon atoms, preferably one to three carbon atoms, and Z is selected from nitrogen or phosphorus, preferably nitrogen.
This class of compounds is illustrated by the following specific examples:
4-( N ,N-dimethyl-N-hexadecyl-ammonio)-2-butenel-sulfonate; 4-(N,N-dimethyl-N-alkylammonio)-2- butene-l-sulfonate, the alkyl group drived from tallow fatty alcohol; 4-(N,N-diethyl-N-hexadecylammonio)- 2-butene-l-sulfonate; 4-(N,N-diethyl-N- tetradecylammonio )-2-butenel -sulfonate; 4-( N,N- dimethyl-N-alkylammonio)-2 butene-l-sulfonate, the alkyl group being derived from the middle cut of coconut fatty alcohol; 4-(N,N-dimethyl-N- octadecylammonio)-2-butene-1 -sulfonate; 4-(N-2- hydroxyethyl, N-methyl, N-tetradecylammonio)-2- butenel -sulfonate; 4-( N ,N-dimethyl-N- dodecylammonio)-2-butene-l-sulfonate; 4-(N,N- dimethyl-N-hexadecylphosphonio)-2-butene-lsulfonate; 4-(N,N-dimethyl-N-alkylphophonio)-2- butene-l-sulfonate, the alkyl group derived from the middle cut of coconut fatty alcohol; and 4-(N,N- diethyl-N-hexadecylphosphonio)-2-butene-1- sulfonate. Specific reference to the above compounds is given only for the purpose of illustration, and it will be appreciated that many other similar variations may be used in this invention so long as the general formula requirements are observed.
The preferred compounds of this invention are 4- (N,N-dimethyl-N-hexadecyl-ammonio)-2-butenel sulfonate; 4-(N,N-dimethyl-N-alkylammonio)-2- butene-l-sulfonate in which the alkyl group is tallow alkyl which approximately consists of a mixture of 66 percent C 30 percent C 4 percent C or in which the alkyl group is middle cut coconut fatty alkyl which approximately consists of a mixture of 2 percent C 66 percent C 23 percent C and 9 percent C It is preferred that that R, and R be selected from methyl, ethyl, propyl, isopropyl, butyl and ethanol.
The unsaturated zwitterionic compounds of the present invention can be made by any convenient method or process. For example, they can be prepared by reacting tertiary amines or phosphines with butene sultones. The butene sultone can be from any source but a ready source is by a sulfonation reaction betwen 1,3- butadiene and an SO dioxane complex.
An SO,,-dioxane complex can be prepared by the following procedure:
The complex readily precipitates out, and is then filtered and washed with dioxane. The filter cake is then ordinarily slurried in dioxane, and butadiene is bubbled through the slurry until all of the solids have disappeared. To the reaction product containing a butene sultone compound and a sulfonated butene polymer is added either a tertiary amine or phosphine compound, e.g., dodecyl dimethyl amine. The reaction proceeds at reflux and a reaction product is formed containing the desired 4-(N,N-dialkyl-N-alkyl)-2-butene-l-sulfonate in substantial yield. NMR and IR analyses have confirmed the desired reaction product.
EXAMPLE 160 g. were added to a mixture of 212 g. dioxane and 588 g. ethylene dichloride. A white solid precipitate which formed was removed by filtering. The precipitate was added to 650 g. dioxane, the mixture was heated to 60C. and butadiene was bubbled in until the solids were reacted. A two phase liquid resulted. The bottom phase, a yellow oil, was added slowly to 474 g. dimethyldodecylamine and 1308 g. acetone. This mixture was refluxed at 59C. and amine values were taken to follow the reaction. Time 0 minutes on amine values is after addition; theoretical value is 56.
Time Amine Value 0 minutes 43 30 minutes 40 minutes 42.4 [80 minutes 4L9 300 minutes 42.5
The material was then chilled in a 0F. box overnight and the white solids removed by filtering and washed with acetone. The solids were dissolved in a 50 percent 3 A alcohol in water solution to 20 percent solids level. The pH was raised to about 9 with 50 percent NaOl-I in order to free the amine from the salt form. This was then filtered to remove the soldium salts and washed with petroleum ether then dried to a solids form. The
material was then redissolved to a 62 percent volatiles 38 percent solids level with water. Analysis confirmed a reaction product of 4-(N-dodecyl-N,N- dimethyl)-2-butene-1-sulfonate.
The discovery that the introduction of one double bond into the radical between cation and anion groups of a zwitterion as described herein produces a compound having surface active performance superior to that of its saturated four carbon counterpart was totally unexpected. The double bond, belived to be the cisstereoisomer, apparently allows positioning of the charged zwitterionic groupings in such a manner as to enhance the surface activity of the unsaturated compounds beyond that of their saturated counterparts.
In preparing detergent compositions, especially valuable as laundering compositions, it is desirable to use the unsaturated zwitterionic surface active compounds of this invention in admixture with detergency builder compouds. Excellent compositions consist of an unsaturated zwitterionic detergent compound of this invention and at least one detergency builder selected from inorganic or organic alkaline builders in a proportion by weight of detergent to builder of :1 to 1:20 and preferably from 5:1 to 1:10. These compositions provide best overall laundering results including soil removal and whiteness maintenance results when used in washing solutions having a pH 6.5 to 11.5, preferably 7 to 11, optionally 8.5 -11.
Water soluble inorganic alkaline builder salts which can be used in this invention alone or in admixture are alkali metal carbonates, borates, phosphates, polyphosphates, bicarbonates and silicates. Ammonium or substituted ammonium, e.g., triethanol ammonium, salts of these materials can also be used. Specific examples of suitable salts are sodium tripolyphosphate, sodium carbonate, sodium tetraborate, sodium and potassium pyrophosphate, sodium and ammonium bicarbonate, potassium tripolyphosphate, sodium hexametaphosphate, sodium sesquicarbonate, sodium orthophosphate and potassium bicarbonate. The preferred inorganic alkaline builders according to this invention are alkali metal tripolyphosphates for built granular compositions.
Examples of suitable organic alkaline sequestrant builder salts used in this invention alone or in admixture are alkali metal, ammonium or substituted ammonium, aminocarboxylates, e.g., sodium and potassium ethylenediaminetetraacetate, sodium and potassium N-(2-hydroxyethyl)-ethy1enediaminetriacetates, sodium and potassium nitrilotriacetates and sodium, potassium and triethanolammonium N-(2-hydroxyethyl)- nitrilodiacetates. Mixed salts of these polycarboxylates are also suitable. The alkali metal salts of phytic acid, e.g., sodium phytate are also suitable as organic alkaline sequestrant builder salts (see U.S. Pat. No. 2,739,942). Sodium ethane-l-hydroxy, 1- diphosphonate, and sodium citrate cam also be used as builders either alone or in mixtures with other builder compounds. Other suitable builders include methylene and ethylene diphosphonates and their derivatives, ethane-1-hydroxy-1,1,2-triphosphonate, sodium itacon ate, and sodium polymaleate and the like.
The unsaturated zwitterionic surface active compounds of the present invention can also be used in combination with other detergent materials selected from anionic synthetic detergents, nonionic synthetic detergents and ampholytic and zwitterionic synthetic detergents.
A laundering method incorporating the discovery of the present invention can be practiced in a number of different ways. Preferably the washing step is followed by rinsing and drying the fabrics. The washing solution can be prepared by adding the granular, tablet or liquid detergent composition prepared according to this invention to any container which contains water at a temperature ranging from about 40F. to about 200F., usually about F. F. The detergent composition concentration in solution can range from about 0.05 percent to 10.50 percent by total weight, and should be added in sufficient amount to provide a concentration of at least 0.005 percent of the zwitterionic detergent compounds. The fabrics can be added to the container or washer before or after the washing solution is added. As is usual in a washing step, the fabrics are then agitated in the detergent solution. While the period of time may vary, an automatic agitator type washer, generally employs a washing cycle which ranges from 8 to 15 minutes.
After the washing step, the washing liquor is drained off or the fabrics are separated from the liquor and thereafter the fabrics are rinsed in clean water. The fabrics can be rinsed as many times as desired in order to insure that washing liquor is removed. Using an automatic washer, it has been found that about four spray rinses and one deep rinse are usually sufficient. for this purpose. Between and after rinsing steps, the bulk of the rinse water is usually drawn from, or spun out of the fabrics. After rinsing, the fabrics are dried. Although rinsing and drying are usual and desirable steps, the important advantage of the invention is achieved in the washing step.
The following compositions will illustrate the manner in which the zwitterionic surface active detergent com pounds of this invention can be used. Included are both liquid and granular formulations. It will be understood, however, that the examples are not to be construed or limiting the scope of conditions claimed hereinafter. These compositions are useful in automatic washers and conventional type washers as well as hand washing operations.
