Tenside der allgemeinen Formel (I), in der R 1 für einen linearen oder verzweigten Alkylrest mit 6 bis 20, insbesondere 8 bis 14 C- Atomen steht, R 2 für H oder CH 3 steht, und M für Wasserstoff, ein Alkalimetall oder eine Gruppierung N+R 3 R 4 R 5 steht, in der R 3 , R 4 und R 5 unabhängig voneinander für Wasserstoff, eine Alkylgruppe mit 1 bis 6 C-Atomen oder eine Hydroxyalkylgruppe mit 2 bis 6 C-Atomen stehen, lassen sich gut in Wasch- oder Reinigungsmittel einarbeiten, besitzen herausragende anwendungstechnische Eigenschaften und können auf Basis nachwachsender Rohstoffe hergestellt werden.
摘要:
Disclosed is a process for the preparation of alkanoate esters of hydroxybenzenesulfonic acids and salts thereof by the steps of (1) contacting or reacting phenol with an alkanoic acid in the presence of trifluoroacetic acid (TFA) and trifluoroacetic anhydride (TFAA) to produce an aryl alkanaoate ester and (2) contacting the reaction mixture of step (1) with a sulfonating agent to convert the aryl alkanoate ester to an alkanaoate ester of hydroxybenzenesulfonic acid. The process provides the economic advantage inherent in using the product of esterification of step (1) without isolation in the sulfonation of step (2).
摘要:
This invention addresses methods and compositions for providing alkyl diphenyl oxide sulfonic acid blends at useful viscosities for use in surfactants such as DOWFAX - containing surfactants. The low viscosity alkyl diphenyl oxide sulfonic acid blend is made by admixing a fatty acid having a carboxylic chain length between 1 and 12 (for example, formic acid, acetic acid, propionic acid, butanoic acid, pentanoic acid, valeric acid, hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, decanoic acid, undecanoic acid, or dodecanoic acid into an alkyl diphenyl oxide sulfonic acid reaction product to provide between 5 weight percentage and 50 weight percentage of fatty acid in the admixture.

In the above formula, the dotted line represents an optional double bond, and R5, R6, R7, R8, R11, R12, X, Y and Z have the meanings given in the specification.
摘要:
Metallic salts useful for inkjet receptor media are disclosed. The metallic salt can be a multivalent metal derivative of an aromatic carboxylic, sulfocarboxylic, sulfophenolic, or combination thereof. The aromatic moiety can be a simple aromatic, a condensed aromatic, a heterocyclic aromatic or a combination thereof. The multivalent metal ion can be derived from the group IIA to VIA and Group IB to VIIIB of elements in the Periodic Table. The metallic salt simultaneously releases the multivalent metal cation and the organic acid anion for both pigment management and ink-drying.
摘要:
Aromatic acids and pharmaceutical compositions of aromatic acids of formula Ar-M-Y and methods for using the pharmaceutical compositions for modulating the activity of the FGF family of peptides are provided. Methods for inhibiting the binding of an FGF peptide to an FGF receptor by contacting the receptor with the aromatic acid are also provided. Methods for treating FGF-mediated disorders by administering effective amounts of one or more of these aromatic acids or pharmaceutically acceptable derivatives thereof that inhibit the activity of one or more FGF peptides are also provided.
摘要:
The present invention relates to a process for the preparation of a purified salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino] alkanoate. The process comprises the steps of: (a) providing a source of 4-sulfophenyl-[(1-oxyalkanoyl)amino] alkanoate; (b) admixing the source with a water-based purification system to form a purification mixture, the water-based purification system having water present at a ratio of 4-sulfophenyl-[(1-oxyalkanoyl)amino] alkanoate to water ranging from about 1:0.05 to about 1:50, preferably from about 1:0.1 to about 1:40; (c) separating a purified salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino] alkanoate from the purification mixture; and (d) collecting said purified salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino] alkanoate. In preferred embodiments, the purification mixture includes a processing aide such as ethyl alcohol, propyl alcohol, isopropyl alcohol, acetone and mixtures thereof.
