Description
Verfahren zur Herstellung eines neuen Derivates einer Aminosulfonsäure. Es wurde gefunden, dass man zu einem neuen Derivat einer Aminosulfonsäure ge langt, wenn man 1 Mol ss-Aminoäthansulfon- säure mit 1 Mol ar-2-Chlormethyl-tetrahydro- naphthalin in Gegenwart eines säurebinden- .den Miltels umsetzt.
Die Umsetzung wird zweckmässig bei 60 bis 75 vorgenommen, wobei :man als säure bindendes Mittel vorteilhaft Natriumcarbonat verwendet.
Das Natriumsalz des erhaltenen Erzeug nisses bildet ein hygroskopisches, in Wasser nicht sehr leicht lösliches Pulver, das gute kapillaraktive EEigenschaftm, insbesondere ein gutes Netzvermögen, besitzt. Es kann als Textilhilfsstoff, z. B. als -Netzmittel, verwen det werden.
Beispiel: 18 Gewichtsteile ss-@aminoäthänsulf onsaures Natrium erhitzt man zusammen mit 100 Ge wichtsteilen Wasser, 800 Gewichtsteilen Me thylalkohol und 24 Gewichtsteilen ar-2- Chlo@rmethyl-tetrahydronaphthaIin am Rück flusskühler zum Sieden, wobei man die Re- Aktionslösung durch Zusatz von Natronlauge stets schwach alkalisch hält.
Nach einigen Stunden ist die Umsetzung beendet. Man neutralisiert das Reaktions- gemisch und dampft dieses im Vakuum. zur Trockne ein. Das getrocknete S@alzgemisöh kann durch Extraktion mit absolutem Al kohol gereinigt werden.
Das erhaltene ss-mon-otetrahydronaphthyl- methylaminoäthansuHons-aure Natrium bil det ein- hygroskopisches, in Wasser nicht sehr leicht lö@sliehes Pulver, das gute kapillar aktive Eigenschaften, insbesondere ein gutes Netzvennöger@, besitzt.
Process for the preparation of a new derivative of an aminosulfonic acid. It has been found that a new derivative of an aminosulfonic acid is obtained if 1 mol of β-aminoethanesulfonic acid is reacted with 1 mol of ar-2-chloromethyl-tetrahydronaphthalene in the presence of an acid-binding agent.
The reaction is expediently carried out at 60 to 75, in which case sodium carbonate is advantageously used as the acid-binding agent.
The sodium salt of the product obtained forms a hygroscopic powder which is not very easily soluble in water and which has good capillary-active properties, in particular good wetting properties. It can be used as a textile auxiliary, e.g. B. as a wetting agent, are used.
Example: 18 parts by weight of sodium ss- @ aminoäthensulfonsaures are heated together with 100 parts by weight of water, 800 parts by weight of methyl alcohol and 24 parts by weight of ar-2-Chlo @ rmethyl-tetrahydronaphthaIin on the reflux condenser to boiling, the Re- action solution by adding Keeps sodium hydroxide solution always slightly alkaline.
The reaction has ended after a few hours. The reaction mixture is neutralized and evaporated in vacuo. to dry up. The dried S @ alzgemisöh can be cleaned by extraction with absolute alcohol.
The obtained ss-mon-otetrahydronaphthylmethylaminoethansuHonic acid sodium forms a hygroscopic powder which is not very easily soluble in water and which has good capillary active properties, in particular good network properties.
