Description
*' tats Patented Oct. 18, 1960 QUAI'ERNARY AlVIlVIONIUM SAELTS F ANTI-IRA- QUINONE DYE COMPOUNDS 8 Claims. (Cl. 260-377) This invention relates to new anthraquinone com- .pounds and their application to the art of dyeing or coloring.
It is well known that polyacrylonitrilefibers are difficult to dye in deep, fast shades without the use of special dyeing techniques, such as, for example, the use of pressure, carriers or the so-called cuprous ion technique involving the use of acid wool dyes. Each of these methods involves one or more disadvantages. The use of pressure involves the use of pressure equipment which is more expensive than the equipment used where no pressure is involved. The use of carriers involves the expense of providing the carriers. Also, when carriers are employed operations for the recovery of the carrier for reuse are involved and these recovery operations add to the expense of the dyeing operation.
While many variations in the cuprous ion technique have been proposed all sufier some disadvantage. One of the chief disadvantages of this method is the fact that it is almost impossible to restrict the amount of copper absorbed to such a low degree that serious browning of the dyed fabric upon exposure to light does not occur.
It is an object of the present invention to provide blue anthraquinone dyes which yield dyeings 'on polyacrylonitrile textile materials which have excellent fastness to light and washing. A further object is to provide watersoluble anthraquinone dye compounds which can be applied to polyacrylonitrile textile materials'in Water solutions. Another object is to provide new quaternary anthraquinone dye compounds capable of dyeing polyacrylonitrile textile materials deep blue shades.
The new anthraquinone compounds of the present in--- vention by means of which the objects of the invention can be accomplished are the quaternaryanthraquinone compounds having the formula:
fi N H2 C H (3 I C O N 0 11112 1?- 0 N R2 1 wherein R and R each represents an alkyl group having 1 to 4 carbon atoms, a hydroxyalkyl group having 1 to 4 carbon atoms, a p-methoxyethyl group or a fi-ethoxyethyl group, R represents an alkyl group, n represents 2, 3 or 4, X- is an anion and wherein taken together also represent a morpholinyl group or a piperidyl group.
Ethylene, tn'methylene, propylene, tetramethylene and Z-methyl trimethylene:
for example, are illustrative of the alkylene radicals represented by C H The new quaternary anthraquinone compounds of the present invention are prepared by quaternizing the anthraquinone compounds having the general formula:
(I? NHa C H C C ON CnHZnN wherein n, R, R and have the meaning previously assigned to them. These compounds which are valuable dyes for polyacrylonitrile fibers, especially modified polyacrylonitrile fibers, are new compounds and are described and claimed in our copending application Serial No. 757,680, filed August 28, 1958.
The anthraquinone compounds having the formula designated II are conveniently prepared by condensing the acid chloride of the appropriate 1-arnino-2-bromo-4- carboxyanilinoanthraquinone with a primary amine having the formula:
have the meaning previously assigned to them. The acid chloride of the 1-amino-2-bromo-4-carboxyanilinoanthraquinone compound is prepared by known methods.
Quaternization of the anthraquinonecompounds having the formula designated II may be carried out in an inert solvent using the known quaternizing agents. A dialkyl sulfate, an alkyl chloride, an alkyl bromide, an alkyl iodide, an aralkyl chloride, an aralkyl bromide or an alkyl ester of para-toluene sulfonic acid, for example, can be employed. Specific quaternizing agents include, for example, dimethyl sulfate, diethyl sulfate, dipropyl sulfate, dibutyl sulfate, ethyl bromide, ethyl chloride, methyl iodide, ethyl iodide, n-butyl iodide, lauryl iodide, benzyl chloride, benzyl bromide, methyl p-toluene sulfonate, ethyl p-toluene sulfonate, n-propyl p-toluene sulfonate and n-butyl p-toluene sulfonate.
Inert solvents that can be employed in the quaternization reaction include, for example, dimethyl formamide, acetone, ethylene glycol monoethyl ether, isopropanol, n-butanol, chlorobenzene and nitrobenzene.
Inasmuch as the new quaternary anthraquinone compounds of the present invention are water soluble they are applied to the polyacrylonitrile textile material from their solution in water, preferably at the boil. The property of water solubility is of real practical importance because dyes are almost exclusively applied from an :capable." It is: interesting to note that no significant dif- 1Q thraquinone were suspended in 100 cc. of dry 'o-dichlorothionyl chloride was removed by passing a stream of dry grams of 3-dimethylaminopropylamine and 2.26 grams of anhydrous sodium acetate were addedand'the reaction aqueous dyebath. Because the dyes are water soluble d th with hot water and dried at 110 C. 11.3 the manufacturer thereof is relieved from the costly procgrams of product identical with that prepared in Example ess of preparing mixes or dispersions that will form lwere bt i d,
suspensions of finely divided solids and the dyer is relieved from the necessity of adding'othersubstances, for example, in order to prevent the suspension or emulsion from breaking. If the dye suspension or emulsion breaks, uneven dyeing of the goods results and the dye fails to deliver the full money value of which it is Example 3 Example 1 was repeated using 1 gram of 1-arnino-2- bromo-4-p-carboxyanilinoanthraquinone and 4 grams of N- (Z-aminoethyl) piperidine. 1-amino-2-bromo-4-p- N- 2- piperidylethyl) carboxamido] anilinoanthraquinone having the formula:

The anthraquinone compounds having the Formula II can be applied to polyacrylonitrile textile materials from an aqueous dyebath in the same manner that water-insoluble cellulose acetate dyestufis are commonly applied to cellulose acetate textile materials. Thus they may be directly applied to the polyacrylonitrile textile material undergoing coloration in the form of an aqueous suspension which can be prepared by grinding them to a paste in the presence of a sulfonated oil, soap, sodium lignin sulfonate, or other suitable dispersing agent and dispersing the resulting paste in water. In this method of dyeing the dye in finely divided condition is intimately dispersed in water and applied directly to the fiber.

One cc. of dimethyl sulfate was added and the reaction mixture resulting was heated at 75 C.-80 C. for 45 minutes. Upon cooling, the reaction mixture was diluted with three times its volume of hexane and the liquid was decanted from the sticky solid. The solid was dissolved in 25 cc. of water, heated to boiling and 1.5 to 2 grams of sodium chloride were added. On cooling to room temperature the solid present in the reaction mixture was recovered by filtration, washed well with a 5% aqueous solution of sodium chloride and then dried at 60 C. in vacuo.

Example 7 0.4 gram of the dye product obtained in accordance with the procedure described in Example 1 and 3 cc. of dimethyl sulfate were warmed together on a steam bath. The resulting solution obtained was dull brown in color. After cooling, the solution was diluted with four times its volume of ether resulting in the precipitation of a sticky solid. The sticky solid was washed with ether and the ether was removed by decantation. The residue reof water, 1 gram of salt was added and after cooling,
the product was recovered by filtration, washed well with an aqueous salt solution and dried. The product obtained is identical tothat of Example 6. It dyes Verel and Orlon textile materials beautiful blue shades having excellent fastness to light and washing.
I Example 8 Example 6.was repeated using 1.5 cc.. of methyl-ptoluene sulfonate instead of dimethyl sulfate. Upon working up the reaction mixture in accordance with the procedure described in Example 6, a dyestuif which dyes Verel and Orlon beautiful blue shades having excellent resistance to light and washing was obtained. 'The dyeings obtained are indistinguishable from the dyeings obtained withthe dyestuffs of Examples 6 and 7. The dyeing was carried out in accordancev with the dyeing procedure described hereinafter.
Example 9 Example 11 One gram of 1-amino-2-bromo-4-m-[N-(2-diethylaminoethyl)carboxamido] anilinoanthraquinone was dissolved in 20 cc. ofacetone, 1' cc. of dimethyl sulfate was added and the acetone was removed by heating on a steam bath.

Further, in-a standard AATCC No. 3 wash test for synthetic materials no loss in color occurred and no staining of the undyed multifiberlnylon, cellulose acetate, cotton, silk,-viscose and wool) fabric took place. Similar results are obtained when an Orlon 42 polyacrylonitrile textile material is dyed. This procedure is applicable to polyacrylontrile textile materials generally. The textile material can be, for example, in fabric, yarn, filament or fiber form.
The primary amine compounds having the Formula III used in preparing the new anthraqu-inone compounds having the Formula II appear to include new as well as old compounds. Many of these amines are specifically disclosed in the prior art'. Those not specifically disclosed can be prepared by the-methodsused to prepare the known compounds The preferred amine B-dimethylaminopropylamine is anarticle of'commerce.
Three general processes by which primary amines having the Formula III can be perpared are set forth hereinafter:
- ]anilinoanthraquinone (1) An amine having theformula:
/R HQN R1 '(IV) is condensed with a chloroalkylnitrile having the formula: Cl( CH CN, and the product obtained is "reduced by sodlum-alcohol or with hydrogen over'Raney nickel to give the desired product:
/R 'mNwHmHN (2) Potassium phthalimide is-condensed with adi- 'brornoalkyl compound having the formula: Br(CH Br to obtain"C H (CO) N(CH Br which is treated with which is hydrolyzed withdilute mineral acid to give the desired product. Method 2'is the well-known Gabriel synthesis.
(3) A secondary amine is added to an unsaturated -nitrile, e.g-. methacrylonitrile, andthe product hydrogenated to the primary amine:
R1 CH: R1 CH:
CH3 CH3 HzNcHfl lHClHaN and CH3 HaNCHqHCHzN as used herein have the meaning previously assigned to them, whilex is 1,2 or 3'and z is 2, 3 or 4.
' The 1 amino Z-brorno-Lcarboxyanilinoanthraquinone compounds used in the preparation of the new anthraquinonc compounds having the Formula II can be prepared bythe procedure "described in. Berichte," vol. 49,
9 page 2167 (1916), wherein the preparation of l-amino-Z- bromo-4-o-carboxyanilinoanthraquinone is described.
As previously indicated, there appears to be no significant difference in the dyeing properties of the new quaternized anthraquinone compounds of the invention regardless of the quaternizing agent used. However, from the standpoint of ease of manipulation and economy we prefer to use dimethyl sulfate.
