Gegenstand der Erfindung ist ein verbessertes Verfahren zum Herstellen von Natnumcyclohexylamidosulfonat durch Umsetzen von Cyclohexylamin und Amidosulfonsaure und Hydrolysieren des erhaltenen Cyclohexylammonium - N - cyclohexylamidosulfonats Natnumcyclohexylanunosulfonat dient als SüßstoffThe invention relates to an improved method for the production of sodium cyclohexylamidosulfonate by reacting cyclohexylamine and Amidosulfonic acid and hydrolyzing the resulting cyclohexylammonium-N-cyclohexylamidosulfonate Natnumcyclohexylanunosulfonat serves as a sweetener
Es sind Verfahren zum Herstellen von Natnumcyclohexylamidosulfonat bekannt bei denen Amidosulfonsaure bei 130 bis 1600C mit Cyclohexylamin neutralisiert, das so erhaltene Cyclohexylammoniumamidosulfonat mit weiterem Cyclohexylamm unter Abspaltung von Ammoniak zu Cyclohexylammomum-N-cyclohexylamidosulfonat bei 180 bis 1900C kondensiert und dieses mit wäßriger Natronlauge in Natrmmcyclohexylamidosulfonat und Cyclohexylamin hydrolytisch zerlegt wirdThere are where neutralizing sulfamic acid at 130 to 160 0 C with cyclohexylamine method for producing Natnumcyclohexylamidosulfonat known, the Cyclohexylammoniumamidosulfonat thus obtained with further Cyclohexylamm with elimination of ammonia to Cyclohexylammomum-N-cyclohexylamidosulfonat at 180 to 190 0 C condenses and this with aqueous sodium hydroxide is hydrolytically decomposed into sodium cyclohexylamidosulfonate and cyclohexylamine
Bei diesen bekannten Verfahren wird die Neutralisation entweder in Gegenwart eines hochsiedenden organischen Losungsmittels oder mit aquimolaren Mengen Cyclohexylamin und Amidosulfonsaure ohne Verwendung eines Losungsmittels oder mit überschüssigem Cyclohexylamin als Losungsmittel durchgeführt Wegen der erforderlichen Temperatur fuhrt die Umsetzung zu einer Reihe von Nebenprodukten, so daß das Endprodukt gelblich bis braun gefärbt ist und mehreren Reinigungsoperationen unterworfen werden muß Die Bildung von Ν,Ν'-Dicyclohexylsulfamid m Mengen von 7 bis 10 % fuhrt zu erbeblichen Ausbeuteverlusten Das Cyclohexylamm muß trocken und rein sein, so daß das nach der Hydrolyse beim Eindampfen des Endprodukts zurückgewonnene Cyclohexylamm getrocknet und durch Destillieren gereinigt werden mußIn these known processes, the neutralization either in the presence of a high-boiling organic solvent or with equimolar Amounts of cyclohexylamine and sulfonic acid without using a solvent or with excess Cyclohexylamine carried out as a solvent because of the required temperature leads the conversion to a number of by-products, so that the end product is yellowish to brown in color and must be subjected to several cleaning operations. The formation of Ν, Ν'-dicyclohexylsulfamide m amounts of 7 to 10% leads to hereditary problems Loss of yield The cyclohexylamm must be dry and pure, so that after the hydrolysis Evaporation of the final product, recovered cyclohexylamm, dried and purified by distillation must become
Es wurde nun überraschenderweise gefunden, daß man zu einem sehr reinen Natnumcyclohexylamido- 3b sulfonat gelangt, wenn man die Umsetzung des Cyclohexylamine mit Amidosulfonsaure in der ersten Verfahrensstufe in wäßriger Losung vornimmt, die erhaltene wäßrige Losung von Cyclohexylammonrumamidosulfonat zur Trockne eindampft, in bekannter Weise das Cyclohexylammoniumamidosulfonat mit Cyclohexylamin kondensiert und das erhaltene Cyclohexylammonium-N-cyclohexylammo&ulfonat mit wäßriger Natronlauge hydrolysiertIt has now surprisingly been found that a very pure sodium cyclohexylamido-3b sulfonate arrives if you react the cyclohexylamine with sulfamic acid in the first stage of the process makes the obtained in aqueous solution aqueous solution of cyclohexylammonrumamidosulfonate evaporated to dryness, in known Send the cyclohexylammonium amido sulfonate with Cyclohexylamine condenses and the resulting cyclohexylammonium-N-cyclohexylammonate hydrolyzed with aqueous sodium hydroxide solution
Die Neutralisation kann bei Zimmertemperatur vorgenommen werden Zur Erhöhung der Löslichkeit des Cyclohexylamm oniumamidosulfonats ist es jedoch zweckmäßig, die Umsetzung bei 30 bis 500C vorzunehmen Eine weitere Temperaturerhöhung ist möglich, bringt aber im allgemeinen keine Vorteile mehrThe neutralization can be carried out at room temperature to increase the solubility of the Cyclohexylamm oniumamidosulfonats however, it is expedient to carry out the reaction at 30 to 50 0 C a further temperature increase is possible, but will generally afford no advantages more
Bei einer besonders vorteilhaften Ausfuhrungsform des erfindungsgemaßen Verfahrens verwendet man als Verfahren zum Herstellen /on Natriumcyclohexylam'idosulfonatIn a particularly advantageous embodiment of the method according to the invention is used as Process for the preparation of sodium cyclohexyl amidosulfonate

Einsatzprodukt fur die erste Verfahrensstufe ein Gemisch aus gleichen Gewichtsteilen Cyclohexylamin und Wasser Dieses Gemisch bildet ein Azeotrop, es fallt beim Eindampfen der Losung von Natnumcyclohexylamidosulfonat nach der Hydrolyse zwanglaufig an, so daß das Destillat aus diesem Prozeß unmitteJbar als Einsatzgemisch fur die erste Verfahrensstufe /erwendet werden kann, wobei keine Reinigung oder Konzentrierung erforderlich ist Die beschuebene Verfahrensweise ist besonders gut durchfuhrbar, wenn man zur Hydrolyse des Cyclohexyllammonium-N-cyclohexylamidosulfonats mit Natronlauge nur so viel Wasser einsetzt, daß das Reaktionsprodukt bei 90 bis 100° C gerade gelost bleibtFeedstock for the first process stage is a mixture from equal parts by weight of cyclohexylamine and water This mixture forms an azeotrope, it falls when the solution of sodium cyclohexylamidosulfonate is evaporated inevitably after the hydrolysis, so that the distillate from this process is inevitable can be used as a feed mixture for the first process stage /, with no purification or Concentration is required The procedure can be carried out particularly well if the hydrolysis of the cyclohexyllammonium-N-cyclohexylamidosulfonate is used with sodium hydroxide solution only so much water uses that the reaction product at 90 to 100 ° C just remains dissolved

Thereafter, the cyclohexylammon-water mixture can be distilled off from the reaction flask as an azeotrope and used again for the preparation of the first stage Reaction vessel with stirring. After pressure filtration, a colorless product is obtained, which is clarified with activated charcoal and recrystallized from water. The yield of pure, kneaded sodium cyclohexyl amido sulfonate is about 88%, based on the amidosulfonic acid used
