SYMMETRICAI. DIQUATERNARY AMMONIUM COMPOUNDS Jesse C. H. Hwa, Levittown, Pa., assignor to Rohm 8: Haas Company, Philadelphia, Pa., a corporation of Delaware N Drawing. Application January 9, 196 Serial No. 557,836

15 Claims. ((11.260-567.6)

The present invention relates to novel symmetrical diquaternary ammonium compounds and to a method for their preparation.

The symmetrical diquaternary ammonium compounds of the present invention may be represented. by the for- X Rl 34 X 7 p in which R, is preferably an alkyl group of no more than two carbon atoms, R is preferably an alkenyl group of eight to twenty carbon atoms, E is preferably an alkylene group of twoto four carbon atoms, and X is preferably a halogen having an atomic weight of about 35.5 to 127.

The symbol R preferably represents a methyl or ethyl group, that is, an alkyl group of no more than two carbon atoms. The two R groups on each of the nitrogen atoms may be taken collectively to represent a divalent saturated aliphatic chain of four to five atoms which jointly with the amino nitrogen atom forms a fiveto six-sided monoheterocyclic amine group such as morpholino, thiamorpholino, pyrrolidinyl, and piperidino groups, and these groups having a lower alkyl substituent, such as a methyl or ethyl group.

The symbol R is preferably an alkenyl group of eight to twenty carbon atoms. Actually, R may be any aliphatic group, of the stated size, that has at least one bond of unsaturation. That is, there may be used alkenyl, alkdienyl, alkynyl groups, and the like, of eight to twenty carbon atoms. The R group may be a straight or branched chain, preferably branched in any'of the known spatial configurations and the bond or bonds of unsaturation may be at any possible locations. For'instance, when R is dodecenyl possible groups include ndodecenyl, isododecenyl, 1,10-dir'nthyl-2-decenyl, 2,7-dimethyl-2-decenyl, 1-ethyl-2-methyl-5-nonenyl, 4-propyl- 5-butyl-2-octeny1, 1,2ediethyl-4-octenyl, 1- propyl-6-ethyl B-heptenyl, and the like. A common commercial form' of the dodecenyl group that yields a compound of this invention that is particularly effective for the present purposes is tet'ramethyloctenyl, in which there are two methyl groups on each ofLthe number five and seven carbon atoms and the double bond'is at the number two location. Typical of the R representations include octenyl, nonenyl, decenyl, dodecenyl, tetradecenyl, pentadecenyl hexadecenyl, octadecenyl, nonodecenyl, eicosenyl, octadienyl, decedienyl, dodecadienyl, octadecadienyl, octynyl, dodecynyl, and octadecynyl.

The symbol X is preferably a halogen having anatomic weight of about 35.5 to 127, i.e., chlorine, bromine, or

iodine. Chlorine is the preferred representation of X. It will be apparent to one skilled in the art that other anions may be satisfactorily employed such as sulfate, methylsulfate, phosphate, acetate, citrate, tartrate, and the like, which may be supplied directly or by metathesis with the halide form of the present compounds or by Patented Apr. 19, 1960 the use of an anion-exchange resin. Generally, an anion be present a single hydroxyl substituent; E may be em- 'ployed in any of its isomeric forms. v

It is essential for the present purposes that the groups R R and X be the same on each of the nitrogen atoms, that is, the present compounds must be spatially symmetrical about the nitrogen atoms with respect to R R and X. The compounds of this invention, in order to be effective for the present purposes, are restrictedas to the size and identity of the substituent groups, the symmetrical molecular configuration, and the presence of aliphatic unsaturation, and preferable branched skeletal structure, in the R groups.

The quaternary ammonium compounds are preferably prepared by bringing together at a reacting temperature, and thereby causing to react, a compound having the formula R1 l R] .N EN R1/ Rr with a compound having the formula R X. The results are generally essentially quantitative. The reaction involves the union of the R X and compounds on a two to one molecular basis in order to form the symmetrical diquaternization products of this invention. If desired, the R X reactant may be used in excess in order to assure completeness of reaction. Completeness of reaction may be indicated by the amount 'of ionizable anion formed, such as halide, and the disappearance of basicity. If an excess of R X is employed it may be removed at the completion of the reaction by distillation or solvent extraction, as desired,

Reaction temperatures may be used in the range of about 25 'C. to the reflux temperature of the reaction mixture, preferably from 50 to C. orup to the reflux temperature, temperatures up to about 265? C. being practical. If desired, there may be used a catalyst,

such as a' polar iodide soluble in the reaction mixture.

Sodium iodide is preferred in this respect.

Reaction times of about two to twenty hours or more are generally employed depending largely on thereac'tion temperature, solvent, and individual reactants used. The

time of reaction is not critical butmerely influences the yield. -As willbe apparent to one skilled in the art, the longer reaction times generally favor higher yields, up to a point, and, of course, some reactants unite more speedily than others.

It is advantageous to employ a volatile inert solvent such as hexane, heptanei, benzene, toluene, ethyl ether, methanol, isopropanoL-Water, chloroform, acetone, 2-

butanone, acetonitrile, acrylonitrile, nitromethane, form- .ethane,

v 3 are substantially water soluble. The product may be washed, if desired, such as with hexane, heptane, and the like to remove unused starting materials. It is often not necessary to isolate the product, from the solvent, particularly if the solvent used is alcohol or water, since the product may be satisfactorily used for the present purposes in an aqueous or alcoholic solution.

There has been set forth, heretofore, the representations of E, X, R and R The reactants R X and R1 B! may be determined by combining the representations of the component parts previously listed. Typical of the reactants that may be employed as R X include octenyl chloride, nonenyl chloride, decenyl chloride, dodecenyl chloride, tetradecenyl chloride, hexadecenyl chloride, octadecenyl chloride, eicosenyl chloride, octad-ienyl chloride, decadienyl chloride, dodecadienyl chloride, octadecadienyl chloride, octatrienyl chloride, octynyl chloride, dodecynyl chloride, and octadecynyl chloride. The other anion representations of X, previously set forth, may be used in place of the illustrative chloride form presented above. The halide representation of X is preferred. Where more than one molecular location of X is possible in the reactant R X, all possibilities are contemplated as long as X is reactive in the present sense, that is, labile enough to undergo the present quaternization under the instant reaction conditions.

Typical of the reactants, having the formula that may be used include N,N-tetramethylethylenediamine, N,N'-tetraethylethylenediamine, N,N'-tetramethylpropylenediamine, N,N' tetraethylisopropylenediamine, N,N'-tetramethylbutylenediamine, 1,4-bis diethylamino 2-butene, 1,4-bis(dimethylamino)-1,3-butadiene, 1,4-bis (dimethylamino)-2-butyne, 1,2-dipiperidinoethane, 1,2- dimorpholinoethane, 1,2 dithiamorpholino 1 methyl- 1,4-dipyrrolidinylbutane, 1,4-dipiperidino-2-butene, l,4-dimorpholino-2-butyne, N,N'-tetramethyl-2-hydroxypropylenediamine, N, N'-tetraethyl-Z-hydroxypropylenediamine.

It is possible, and frequently advantageous, in the preparation of some of the present compounds to first prepare the halide form, such as chloride, in a manner already set forth, and then prepare any other desired form, within the present definition, by metathesis or ion-exchange methods. For instance, any of the present compounds in halide form, may be converted to the hydroxide form through the use of silver oxide, or the like, and then converted to any desired anion form by acidifying with an acid of choice such as sulfuric, phosphoric, acetic, and others within the range and spirit of this invention. In

CH3 CH3 CH: CH:

similar manner, an anion-exchange resin may be employed. Any of the present compounds, in halide or hydroxide form, maybe converted to any desired anion form through the use of an anion-exchange resin in the desired anion form. For instance, there may be used an insoluble, cross-linked, styrene-divinylbenzene copolymeric quaternary ammonium salt in its sulfate, phosphate, or like form to convert a present compound, in halide or hydroxide form, to a desired form, such as phosphate, sulfate, and the like.

vacuum desiccator.

The symmetrical diquaternary ammonium compounds of this invention are valuable non-durable anti-static agents for hydrophobic fibers, such as nylon, Dacron, and Orlon. They are useful fungicides, in a wide range of concentrations, for example, against Stemphylium sarcinaeforme and Monilinia fructicola. They are, also, effective bacteristats and bactericides in dilutions of up to 1:50,000 and greater, particularly against Micrococcus pyogenes var. aureus and Salmonella typhosa. The present compounds exhibit advantageous characteristics as wetting, emulsifying, and dispersing agents and as detergents.

The compounds of this invention are valuable as detergent-sanitizers and may be employed in meat plants to sanitize cutting tables, grinders, and the like, in fruit processing operations, for instance, to wash and sanitize lemons, oranges, and grapefruit, and in dairy farms to sanitize dairy equipment and utensils.

A suitable detergent-sanitizer formulation for use in meat plants includes, by weight, 5% of a compound of this invention, 2.5 to 5.0% of octylphenoxypolyethoxy- 'ethanol, 20 to 40% soda ash, 20 to 40% sodium metasilicate, and the remainder sodium tripolyphosphate. One ounce of this formulation is used per gallon of water. For sanitizing citrus fruit there is preferably used one part of a present compound in 5000 parts of water. For use in dairy farms, there may be used 10% of a quaternary ammonium compound of this invention, 10% of octylphenoxypolyethoxyethanol, 7% of trisodium phosphate, and 73% of water. One ounce of this solution is used per four gallons of water. The instant compounds in aqueous solution, in amounts of about 0.5 to one ounce to one hundred pounds of dry fabric, are excellent as a final diaper rinse to prevent diaper rash. These compounds are, also excellent premise sanitizers where they may be employed in concentrations of about 0.1 to 2.0% in aqueous cleaning solutions.

The symmetrical diquaternary ammonium compounds of this invention and their method of preparation may be more clearly understood from the following examples, which are presented by way of illustration and not by way of limitation. Parts by weight are used throughout.
