Abstract:
Maleic acid derivatives of hydroxy sulfonated fatty acid esters were prepared by heating the lauric acid salt of 1-chloro-2-hydroxypropane-3-sulfonic acid (NaCHPS) with maleic anhydride under reflux The surfactants thus obtained exhibited superior foaming and wettability to initial detergents that were prepared from lauric acid Amide derivatives of lauric surfactants were prepared by reacting sodium salt of lauric acid amide with NaCHPS under reflux, in the presence of cello-solve and xylene In acidic medium these amide derivatives possess better foaming properties and wettability than the initial detergents
An der Hydroxylgruppe sulfonierte Fettsaureester als oberflachenaktive Stoffe VI: Ester- und Amid-Derivate als Tenside
Die Maleinsaure-Derivate der an der Hydroxylgruppe sulfonierten Fettsaureester wurden durch Erhitzung von Laurinsauresalze der 1-Chlor-2-hydroxypropan-3-sulfonsaure (NaCHPS) mit Maleinsaureanhydrid unter Ruckflus hergestellt Die so erhaltenen Tenside weisen bessere Schaumfahigkeit und Benetzbarkeit auf als die ursprunglichen Detergentien, die aus Laurinsaure hergestellt wurden Durch Umsetzung von Natriumsalz des Laurinsaureamids mit NaCHPS unter Ruckflus bei Gegenwart von Cellosolve und Xylol wurden die Amid-Derivate des Laurinsaure-Tensids dargestellt In saurem Milieu besitzen diese Amid-Derivate bessere Schaumeigenschaften und Benetzbarkeit als die Ausgangsdetergentienread more

TL;DR: In this paper, a pre-treatment for glycoprotein analysis is proposed. But the pre-processing process is performed by a protein solubilizer, and an oligosaccharide is efficiently released from a sample if reductive alkylation and /or digestion by proteinase are carried out under the presence of the said solubiliizer at the first step.

Method of serum pre-treatment for glycomic analysis

TL;DR: In this paper, a pre-treatment for glycomic analysis of a glycoprotein derived from a living body is presented. But the pre-treatment is not suitable for the analysis of complex glycoproteins, since it requires reductive alkylation and/or digestion by a proteinase.

TL;DR: In this article, the general formula RCOOCH2CHOHCH2SO3M (where M is alkali or other metal) has been synthesized from four saturated (C12 to C18) and four unsaturated (C18 −, C182−, C183− and Ricinoleic) fatty acids.
