it has already been proposed to use pyridine and other nitrogen-containing organic bases having a structure similar to benzene as wettin out and emulsifyingagents. But the mentioned 5 products either are sparingly soluble or even insoluble in water; or they have, as for instance the pyridine, ,such a disagreeable odor that their use is unavoidably objectionable to the consumer. Furthermore these'bases possess such a weak allil kalinity that they are not capable of forming soluble in water, and in part due to properties salts with weak acids, such as, for example, fatty or resinous acids. And their salts formed by reaction with strong or mineral-acids fail to have the above mentioned properties.

Now it has been foundthat these defects of pyridine and the other similar nitrogen-containing organic bases may be avoided by subjecting such bases to a hydrogenation process to produce piperidine or its homologues or the hydrogenated 2o chinoline-bases, which products when combined with carboxylic or sulphonic acids aresuitable as washing, emulsifying and wetting-out agents, the beneficial properties being due in part to the hydrogenated products themselves if the same are of the reaction products gained through. the reaction and/or retained from the initial materials.

Piperidine itself, for example, possesses a wetting power in rather weak water solutions, which makes it far superior to pyridine. Therefore by using it in the diflerent technical processes, for instance in the textile-, leatherand paper industries, enormous advantages are obtained.- For instance its reaction products or salts formed with oleie acid or ricinoleic acid, or with Turkey-redoil, resinous acids and similar products possess a washing, cleansing and emulsif s power, which is far superior not only to that of ordinary soaps but also for instance to such soaps which besides the real soap-body contain higher molecular alcohols and similar emulsifying agents.

Another advantage is that the mentioned compounds are soluble without difllculty in organic solvents, in which property they difler from ordinary soaps, which are difli'cult to combine, particularly with hydrocarbons. Therefore they are fit especially for the production of water-soluble oils, as boring oils and textile oils, that is, for all those purposes in which the creation of dispersed systems is desired.

Example.100 kgs. of piperidinc are mixed with 290 kgs. of ricinoleic acid and simultaneously with the increase in temperatureof the mass due to the exothermic nature of the-reaction, a

- April so, 1929 iCi. 252-1) are formed by the above mentioned example of this process, products which may be used as washing, cleansing, and wetting-out agents in difierent technical operations. Instead of the piperidine as mentioned in the above example, its homologues and substitution products, and also hydrated chinoline-bwes may be used; instead of the ricinoleic acid there may be used also other carboxylic acids of the aliphatic, aromatic or hydrocyclic series, or sulfonic acids, as for instance Turkey-red-oil, benzeneor naphthalene-sulfonic acids, etc.
