Description
Verfahren zur Darstellung eines Gemisches von Schwefelsäureabkömmlingen organischer Verbindungen. Das Hauptpatent Nr.<B>165818</B> betrifft ein Verfahren zur Darstellung eines seifenartigen Schwefelsäureabkömmlings einer organischen Verbindung, gemäss dem man einen reaktions fähigen am Sauerstoff alkylierten Oxyfett- säureester, nämlich den (Oxy-äthoxy)-essig- @äure-dodecylester, mit sulfonierenden Mitteln behandelt.
Es wurde gefunden, dass man bei dem Verfahren auch von dem Gemisch der Ester aus Phenoxyessigsäure und dem durch Re duktion von Palmkern- bezw. Cocosfetten gewonnenen Pettalkoholgemisch ausgehen kann.
Auch hier kann die Sulfonierung mit star ker Schwefelsäure, SOs-haltiger Schwefelsäure, SOs oder seinen Anlagerungsprodukten an organische Verbindungen, Chlorsulfonsäure und dergleichen, vorgenommen werden, wobei man in Gegenwart von Lösungs-, Verdün- nungs- oder wasserentziehenden Mitteln ar beiten kann.
<I>Beispiel:</I> In<B>1000</B> Gewichtsteile konzentrierte Schwefelsäure werden bei gewöhnlicher Tem peratur unter Rühren 300 Gewichtsteile eines Gemisches der Ester von Phenoxyessigsäure und dem Gemisch höherer Fettalkohole, wie es .durch Reduktion von Palmkernöl bezw. Cocosöl gewonnen wird, eingetragen. Die Reaktion wird so lange fortgesetzt, bis eine herausgenommene Probe klar wasserlöslich ist. Die homogene Reaktionsmasse wird darnach auf Eis ausgetragen.
Das neue Sulfonsäuregemisch lässt sich nach den üblichen Verfahren, zum Beispiel durch Aussahen, isolieren.
Das Natriumsalz bildet in reinem Zustand ein weisses Pulver, das sich in Wasser löst; die Lösungen besitzen hohes Schaumvermögen und gute Netz-, Wasch- und Emulgiereigen- schaften. Sie sind in weitgehendem Masse kalk-, bittersalz-, kochsalz- und auch säure beständig.
Process for the preparation of a mixture of sulfuric acid derivatives of organic compounds. The main patent no. <B> 165818 </B> relates to a process for the preparation of a soap-like sulfuric acid derivative of an organic compound, according to which a reactive oxyfatty acid ester alkylated on oxygen, namely (oxy-ethoxy) -acetic- @ acid- dodecyl ester, treated with sulfonating agents.
It has been found that in the process you can also use the mixture of the esters of phenoxyacetic acid and the reduction of palm kernel and / or. Pett alcohol mixture obtained from coconut fats can go out.
Here, too, the sulfonation can be carried out with strong sulfuric acid, SO2-containing sulfuric acid, SO2 or its addition products with organic compounds, chlorosulfonic acid and the like, it being possible to work in the presence of solvents, diluents or dehydrating agents.
<I> Example: </I> In <B> 1000 </B> parts by weight of concentrated sulfuric acid, 300 parts by weight of a mixture of the esters of phenoxyacetic acid and the mixture of higher fatty alcohols, as it. By reduction of palm kernel oil or . Coconut oil is obtained, registered. The reaction is continued until a sample taken is clearly soluble in water. The homogeneous reaction mass is then poured onto ice.
The new sulfonic acid mixture can be isolated by the usual methods, for example by looking.
In its pure state, the sodium salt forms a white powder which dissolves in water; the solutions have a high foaming power and good wetting, washing and emulsifying properties. They are to a large extent resistant to lime, Epsom salt, table salt and acid.
