SULPHURIC ACID DERIVATIVES OF CARBOXYLIC ARYLIDES No Drawing. Application May 27, 1932, Serial No. 614,032, and in Germany April 12, 1929 13 Claims.
in which X is either OH (acid), 031 (ester),
(anhydride R1 being an aliphatic radicle} or halogen, and R contains from 5 to carbon atoms with an aromatic primary or secondary amine, which is free from aliphatic alcoholic and. chromophorous groups, the resulting arylides being then reacted with sulphonating agents to form either'sulphohic acids or sulphuric esters, or mixtures of both, or products which contain both sulphuric ester and sulphonic groups, if the arylides are free or only contain an insufilcient quantity of sulphuric ester and/or sulphonic acid radlcles. The acid components of the arylides do not include mixed aliphatic aromatic acids but may be chosen from any saturated aliphatic acids containing from 6 to 16 carbon atoms especially from those of oils or fats of vegetal, i. e. animal or vegetable origin. Instead of the free acids, their anhydrides or halides or the oils or fats themselves (esters) may be employed. Similarly, the synthetic high molecular fatty acids obtainable by the oxidation of paraffin wax and similar high molecular hydrocarbons by means of gase- 40 ous oxidizing agents may be employed or saturated resinic or naphthenic acids; lower aliphatic carboxylic acids containing at least 6 carbon atoms, such as caproic acid, may also be employed. Further specific examples of the acids are for example heptylic, caprylic, nonylic, caprinic, lauric, myristie and palmitic acids as well as the corresponding hydroxycarboxylic acids, such as hydroxy-louric acid, or mixtures of such acids, The said acids may also contain other substituents such as nitro or amino groups. p
The said aromatic amines may be chosen from aniline, di-phenylamine, benzidine, biphenyl amines or from naphthylamines and like aromatic amines. In any case these amines must not contain aliphatic alcoholic groups since otherwise esters might be obtained instead of the desired amines, and the amines must be free from chrcmophorous groups since otherwise colored compounds might be obtained which cannot be used for the purposes intended. The said bases may be employed in the free state or also in the form of their salts when alkaline agents are present during the formation of the arylides. As already stated the acid components may contain one or more sulphonic acid or sulphuric ester groups and the aromatic amines may contain sulphonic groups and in these cases the subsequent sulpho nation may be dispensed with; the arylides containing a lower number of sulphuric ester or 5111-- phonic groups are usually suitable as washing and scouring agents and their solubility in water may be increased by introducing further sulphonic acid groups, or of sulphuric ester groups if the acid radicles contain hydroxyl groups. Thus, for example, the carboxylic acids may be converted into arylides with the aid of amino sulphonic acids as for example sulphanilic acid and the like; on the other hand the. carboxylic acids may contain sulphuric ester and/or sulphonic groups as for example hydroxy-stearic sulphonic acid or its methyl ester (obtainable by sulphonating oleic methyl ester with chlorsulphonic acid in the presence of ethyl ether and subsequent washing with alkali), the sulphuric ester of hydroxystearic methyl ester (obtainable by acting with dimethyl sulphate on the sodium salt of hydroxystearic sulphuric ester which latter can be obtained by acting on oleic acid with sulphuric acid at about 20 C.) dihydroxy-stearic sulphuric ester (obtainable from ricinoleic acid and the like).
Generally speaking it is advisable to take higher amines, such as naphthyl amines for the conver sion when lower carboxylic acids, such as caproic acid or another acid containing up to 10 carbon atoms are employed, and higher carboxylic acids or their derivatives, such as lauric acid and myristic oil, when a lower amine, such as aniline, is used. Particularly suitable are in many cases arylides which have been prepared from higher carboxylic acids, or their derivatives, and from the higher aromatic amines. Stearic acid or still higher carboxylic acids are not employed since products prepared therefrom show an insufd cient solubility and sensitivity to precipitation by lime compounds. Arylides from lower acids and lower amines may be usefully employed as wetting agents in baths of a rather high content s such as are used for many purposes of the industries.
The action and results of the treatment with sulphonating agents depend on the arylides to be worked and on the conditions of the treatment. Sulphuric esters, for example, can be obtained from arylides containing hydroxyl groups as pointed out above. For the production of sulphuric esters the reaction may be carried out with concentrated sulphuric acid or also with stronger sulphonating agents, such as fuming sulphuric acid, sulphur trioxide or chlorsulphonic acid, which latter agents or mixtures thereof with sulphuric acid are usually preferred. The reaction may be carried out in the presence of diluents, such as carbon tetrachloride, trichlor ethylene, nitrobenzene, acetic acid and the like which usually allow of reducing the temperature of working, and/or in the presence of agents removing water, such as anhydrides or chlorides of organic or inorganic acids. At least one molecular proportion of sulphonating agent is usually employed with each molecular proportion of the arylide concerned, but in the aforesaid case of acting on compounds containing hydroxyl groups with strong sulphonating agents, such as sulphur trioxlde or chlorsulphonic acid or with mixtures of milder sulphonating agents with the strong sulphonating agents or with agents removing water, the quantity of the strong sulphonating agents, or of the agents removing water should not exceed one molecular proportion for each hydroxyl group. In most cases, the temperature employed during the reaction should not con siderably exceed 40 C. when more than one molecular proportion of sulphonating agent is employed for each molecular proportion of arylide.
If, however, sulphonic acids are to be produced and when the primary reaction products do not already contain one or more sulphonic groups, the temperature of a sulphonation by means of sulphuric acid monohydrate must exceed 40 C., a temperature of about 100 C. being preferably chosen, since otherwise sulphuric esters might be formed if hydroxyl groups be present or no reaction takes place. When stronger sulphonating agents, such as fuming sulphuric acid, sulphur trioxide or chlorsulphonic acid or mixtures of mild sulphonating agents with these or with agents removing water be employed for this sulphonation of compounds containing one or more hydroxyl groups, the quantity of these strong sulphonating agents or of the agents removing water must exceed one molecular proportion per each hydroxyl group present. It is obvious that variations of the conditions described may lead to the production of mixtures of products of the said different types. When working with considerable quantities'of strong sulphonating agents sulphonic radicles may be introduced into an aliphatic radicle of such an arylide together with a sulphonation of the nucleus.
The products according to the present invention correspond to the general formula wherein RCO denote a radicle of an aliphatic, that is an open chain aliphatic or cycloaliphatic, saturated carboxylic acid containing from 6 to 16 carbon atoms, R1 denotes an aromatic monoor polynuclear radicle free from aliphatic and chromophorous groups, whereas X denotes hydrogen or a radicle of the kind denoted by Rl or the same as R1. In any case R or R1, or both, will contain at least one sulphonic acid radicle, or R will contain a sulphuric ester radicle and R1 may then contain one or more sulphonic acid radicles. As another possibility R may contain both a sulphuric ester radicle and a sulphonic acid radicle, as may happen for example by a condensation of a hydroxy-fatty acid sulphonic acid with an amine, or amine sulphonic acid, and subsequent treatment with a sulphonating agent. The number of carbon atoms in RrCO cannot be chosen below 6, since, otherwise, the products would not substantially showthe desired properties.
The resulting products are distinguished by excellent wetting properties, in neutral, acid or also alkaline baths. The products are also not precipitated by the constituents of hard water. Consequently the products according to the present invention constitute highly valuable assistants for all the branches of the textile and allied industries. Anilides prepared from hydroxylbearing fatty or resinic acids, and treatment with a sulphonatng agent may or the condensation of higher prlmary aromatic amines with carboxylic acids containing sulphonic or sulphuric ester groups may generally find useful application espec'ally as wetting agents, whereas arylides prepared from fatty acids free. from hydroxyl groups, and sulphonation, are particularly valuable washing, scouring, softening and emulsifying agents, as well as the products prepared by the condensation of high molecular saturated carboxylic acids and aromatic primary amines containing sulphonic groups. The secondary arylides are particularly stable even in alkaline baths, have a high emulsifying and levelling power and a far reaching power for dispersing water-insoluble or difflcultly water-soluble solid substances, such as alkaline earth metal soaps, water-insoluble dyestuffs or other water-insoluble coloring mater'als, fats, waxes and the like.
The arylides according to the present invention may be employed as such or in conjunction with other wetting or emulsifying agents, such as soaps, products of the type of Turkey red oils, sulphonic ac'ds of aromatic and especially of polynuclear compounds or their salts, hydroxyalkyl amines, quaternary ammonium bases or their salts, or with protective colloids,-such as glue, gelatine or vegetable mucilages or gums. Salts as for example soda, sodium bicarbonate, waterglass, common salt, neutral or acid sod um sulphate may be added, or organic solvents, such as monocresyl ethylene glycol ether, trichlorethylene or bleaching agents, such as perborates, percarbonates, para-toluene sulphonic chloramide sodium. The said agents are employed in quantities depending on the desired purpose and several of them may be added conjofntly. Thus, for example, the quantity of these additions may be the same as that of the arylides or considerably higher depending on the purposes of emulsifying, wetting, washing, cleaning or dispers'ng solid water-insoluble materials in water. In baths for the treatment of textiles the quantity of the sulphonated arylides may be as low as a few per cent or even a few per thousand of the whole liquors.
All the products accord ng to the present invention must be free from nitro and auxochromic groups, since otherwise they would be inoperative for the different purposes of their application and should preferably contain at least 12 carbon atoms.
The present application is a continuation in part of the application Ser. No. 441,717, filed April.
