Definitions
- the invention relates to a new acidic galvanic nickel bath which, in addition to conventional glossing and wetting agents, contains special heteroaromatic sulfobetaines as glossing and leveling agents.
- reaction products of heterocyclic nitrogen bases of the aromatic type with sultons as brighteners and leveling agents in galvanic nickel baths. According to their chemical structure, they represent internal salts of aminoalkanesulfonic acids (sulfobetaines).
- sulfobetaines aminoalkanesulfonic acids
- DAS 11 91 652 Another group of gloss additives for acidic galvanic nickel baths is described in DAS 11 91 652. These are sulfobetaines of aromatic type heterocyclic nitrogen bases which are obtained, for example, by alkylation of pyridine with dialkyl sulfates. An alkyl sulfate group acts as the anion here.
- This type of brightener also brings satisfactory leveling values only in the high current density range.
- the aim of the invention was. in finding means which do not have these disadvantages and which are particularly effective even at low current densities.
- Nitrogen bases from which the brighteners are made obey Formula II in the R, R 1 and R 2 are defined according to formula I.
- aromatic type e.g. Pyridine, imidazole, thiazole, pyridazine, pyrazine, pyrimidine, quinoline, isoquinoline and others such as 1,2 and 1,3-benzdiazines, naphthiridines, pyridopyridines, triazines and acridines.
- R , R 1 and R 2 are, for example .
- R , R 1 and R 2 are, for example .
- Pyridine, picoline, quinoline, pyrimidine and isoquinoline are preferably chosen as starting bases.
- the nitrogen bases are first arylalkyl halides of the formula III implemented in which R 3 and n are defined according to formula I in the claim and Hal is chlorine or bromine.
- n 1 to 3 and R 3 represents a phenylene or thienylene radical which is unsubstituted or by chlorine, bromine, C 1 - to C 4 -alkyl, such as methyl, ethyl, n- and isopropyl or n and isopropyl groups can be substituted.
- the - (CH 2 ) n group can thus mean the methylene, ethylene or n-propylene group.
- Preferred compounds of the formula III are arylalkyl halides, such as benzyl chloride, phenylethyl chloride or phenylpropyl chloride, ie R 3 in this case means the unsubstituted phenylene radical.
- R 3 in this case means the unsubstituted phenylene radical.
- the sulfonation is conveniently carried out in aliphatic chlorinated hydrocarbons such as ethylene chloride, propylene chloride and others. by.
- Suitable counter cations are alkali metal and the equivalent amount (“half” amount) of alkaline earth metal or divalent transition metal ions, such as iron or nickel.
- Optionally substituted ammonium ions also fulfill this function - NH 4 ⁇ , cyclohexylammonium, tributylammonium and others may be mentioned. Sodium, potassium or cyclohexylammonium cations are particularly preferred.
- the compounds according to the invention have the advantage of being toxicologically harmless in synthesis and use.
- benzylpyridinium chloride has been used for years as a leveling agent in the dyeing of anionically modified polyacrylonitrile fibers.
- the sulfobetaines obtained in this way are more stable in the weakly acidic medium (application conditions) than the acid-sensitive sulfuric acid half-esters.
- Aromatic sulfonic acid groups carry LJ, which may occur due to electrochemical degradation and thus still act as secondary brighteners.
- the baths contain the betaines to be used according to the invention in amounts of 0.05 to 3 g / l, preferably 0.1 to 0.5 g / 1 bath liquid. Otherwise they contain the usual primary and secondary brighteners, such as acetylene alcohols, acetylenamines or oxyalkylated acetylene alcohols or sulfonamides, saccharin, vinyl sulfonate, bisbenzenesulfonamide and others. in amounts of 0.1 to 5 g / l or 0.01 to 3 g / l. They also contain conventional wetting agents in concentrations of 0.1 to 1 g / l.
- the mixture is neutralized with 444 parts of calcium hydroxide, 15 parts of activated carbon are added, gypsum and activated carbon are removed and the solution of the benzylpyridinium sulfobetaine is adjusted to a content of 50% active substance by concentration.
- the benzyl-2-picolinium chloride is prepared and 658.5 parts are introduced into 2600 parts of ethylene chloride.
- the benzylmethylimidazolinium chlorides are prepared and 622.5 parts are introduced into 2600 parts of ethylene chloride.
- benzyl-2-picolinium sulfobetaine instead of benzylpyridinium sulfobetaine in Example 25, benzyl-2-picolinium sulfobetaine according to Example 2 was used as brightener and leveler.
- products according to the prior art were used as leveling agents and brighteners, namely pyridinium propane sulfonate and pyridinium (hydroxyethyl sulfate-2) according to DT-AS 11 91 652.
- benzylpyridinium sulfobetaine instead of benzylpyridinium sulfobetaine according to example 25, benzyl-4-picolinium sulfobetaine (example 5) was used.
